How I Selected These Products
I started by looking at batteries that actually fit the Ford Explorer key fob. That means CR2450 size, 3V output, and lithium chemistry. Every pick here matches those exact specs so you don’t end up with something that won’t work.
Value mattered too. I compared how many batteries you get per pack and what real buyers paid. A cheap per-battery cost means nothing if the batteries die fast, so I balanced price against performance claims like shelf life and brand reputation.
User feedback sealed the deal. I only kept products with at least 4.4 stars and hundreds of honest reviews. If multiple people said a battery worked great in their Ford key fob, that carried a lot of weight in my final ranking.
Best Overall
Energizer 2450 Lithium Coin Battery
2-Pack | 3V Lithium | 12-Year Shelf Life | Amazon’s Choice | 4.8 Stars (6,397 Ratings)
- Energizer 2450 Lithium Coin Battery with child resistant packaging
- Delivers long-lasting, dependable performance in specialty devices like...
This is the battery I trust most for my own Ford Explorer key fob. The Energizer 2450 Lithium Coin Battery has a 12-year shelf life, which means you can stash the spare pack in your glove box and forget about it until you need it. With 30,000+ bought in the past month and a 4.8-star rating from nearly 6,400 people, it’s the clear crowd favorite for a reason.
This 2-pack is perfect if you just need a replacement for your key fob and a backup. My only gripe is that you get just two batteries, so if you’re outfitting multiple remotes or other devices, you’ll want a bigger pack. For a single car key fob swap though, this is the one I’d grab first.
✅ Pros
- 12-year shelf life means long-term storage without worry
- 4.8 out of 5 stars from over 6,300 verified buyers
- Amazon’s Choice badge with 30K+ bought in past month
- Energizer brand reliability you already know
❌ Cons
- Only 2 batteries per pack, not ideal for multiple devices
- Per-battery cost is higher than multi-pack options
Best Shelf Life
PHILIPS CR2450 Battery
5-Pack | 3V Lithium | 10-Year Shelf Life | Amazon’s Choice | 4.8 Stars (823 Ratings)

- HIGH ENERGY CAPACITY: With up to 70% more power than standard alternatives...
Philips is a name I trust for electronics, and their CR2450 battery lives up to that reputation. The 10-year shelf life means these will still be ready to go when your Ford Explorer key fob eventually needs another swap. I like that this 5-pack gives you extras for garage door openers or MyQ battery backups without breaking the bank.
This is the best pick if you want a multi-pack from a household brand name. The downside is that Philips doesn’t have the same decades-long history in coin cells as Energizer or Panasonic, so some buyers might stick with what they know. For the price and quantity though, it’s hard to beat.
✅ Pros
- 10-year shelf life for worry-free storage
- 5-pack gives you spares for other devices
- 4.8-star rating with Amazon’s Choice badge
- Works with car key fobs, medical devices, and MyQ
❌ Cons
- Less established in coin cell market vs. Energizer
- Only 823 ratings so far, less crowd-tested
Best Child-Safe Packaging
Panasonic CR2450 3.0 Volt Long Lasting Lithium Coin Cell Batteries in Child Resistant
2-Pack | 3V Lithium | Child-Resistant Packaging | Amazon’s Choice | 4.8 Stars (1,614 Ratings)
- LONG LASTING PERFORMANCE: Panasonic CR2450 3.V batteries are engineered to...
- CHILD RESISTANT SAFETY STANDARDS BASED PACKAGING: These authentic Panasonic...
Panasonic builds these with child-resistant packaging that meets safety standards, which matters if you’ve got kids around the house. I’ve used Panasonic coin cells for years and they consistently deliver reliable power. With 4,000+ bought in the past month and a 4.8-star rating, this 2-pack is a solid choice for your Ford Explorer key fob.
This is ideal if safety packaging is a priority for you, or if you just want a trusted Japanese brand. The catch is the per-battery cost is higher than most competitors here—you’re paying extra for that child-resistant design and brand name. If you need bulk, look elsewhere.
✅ Pros
- Child-resistant, standards-based packaging for safety
- 4.8 stars from 1,600+ ratings
- Amazon’s Choice with 4K+ bought in past month
- Trusted Panasonic quality from a major electronics brand
❌ Cons
- Higher per-battery cost than most competitors
- Only 2 batteries, not great for multi-device households
Best Budget 5-Pack
PGSONIC CR2450 3V Lithium Battery (5pcs)
5-Pack | 3V Lithium | 620 mAh Capacity | 32g Weight | 4.6 Stars (22,468 Ratings)
- Grade AA batteries: 3 Volt, fresh with strong & reliable power, high energy...
- Long-lasting plus 5 years shelf-life: premium performance in the industry
PGSONIC is the value king here with a 5-pack that costs less per battery than almost anything else on this list. It has a 620 milliamp_hour capacity, which is solid for a CR2450, and over 22,000 ratings with a 4.6-star average. I’ve seen 10,000+ bought in the past month, so people are clearly happy with these in their key fobs.
This is the smart pick if you need multiple batteries for various devices and want to save money. The honest limitation is that PGSONIC isn’t a household name like Energizer or Panasonic, so you’re trading brand recognition for value. For a key fob battery that does the same job, that trade-off is worth it.
✅ Pros
- 620 mAh capacity for reliable key fob performance
- 22,000+ ratings with a strong 4.6-star average
- 10K+ bought in past month shows real demand
- 5-pack gives excellent value for the price
❌ Cons
- Less brand recognition than major competitors
- No stated shelf life on the product page
Best Bulk Energizer
Energizer CR2450 Lithium Battery
6-Pack | 3V Lithium | Amazon’s Choice | 4.7 Stars (40,972 Ratings) | 3K+ Bought in Past Month
- Item Package Length: 3.81cm
- Item Package Width: 4.826cm
This is the Energizer 6-pack for anyone who wants the brand they know and enough batteries to cover multiple devices. With over 40,000 ratings and a 4.7-star average, this is one of the most-reviewed CR2450 batteries on Amazon. I like that you get six batteries at a per-count cost that’s lower than the 2-pack from the same brand.
This is perfect if you have multiple Ford key fobs, garage door openers, or other CR2450 devices around the house. The downside is that this listing sometimes sells through third-party sellers that don’t offer free Prime shipping, so double-check the seller before you buy. For bulk from a trusted brand, this is a great deal.
✅ Pros
- 40,972 ratings with a 4.7-star average—most reviewed here
- 6-pack gives you plenty of spares for the whole house
- Energizer brand reliability you can count on
- Amazon’s Choice badge with strong sales
❌ Cons
- Some sellers may not offer free Prime shipping
- No shelf life stated on the product page
Best Low-Cost 6-Pack
NICEBATT CR2450 3V Lithium Battery 6 Pack
6-Pack | 3V Lithium | Amazon’s Choice | 4.8 Stars (152 Ratings) | 2K+ Bought in Past Month
- Battery:The battery is a high-performance coin cell battery designed for...
- Long Lasting Power: Uses high density battery cells, the energy density...
NICEBATT gives you six batteries at a per-count cost that’s hard to beat anywhere on this list. It has a 4.8-star rating and the Amazon’s Choice badge, plus 2,000 units sold in the past month. For a Ford Explorer key fob replacement, these work just as well as the big names.
This is the smart pick if you want the most batteries for your money and don’t care about brand prestige. The trade-off is that NICEBATT is a lesser-known brand with only 152 ratings, so you’re relying on less long-term feedback. For the price of a coffee, it’s worth a shot.
✅ Pros
- 6-pack at an extremely low per-battery cost
- 4.8-star rating with Amazon’s Choice badge
- Exclusive Prime price for members
- Works with key fobs, door sensors, and security systems
❌ Cons
- Only 152 ratings, less crowd-tested than top picks
- No stated shelf life on the product page
Best for Garage Openers
Tenergy CR2450 Battery
5-Count | 3V Lithium | Amazon’s Choice | 4.7 Stars (951 Ratings) | 1K+ Bought in Past Month
- 5 pack of CR2450 button cell batteries.
- Tenergy's long lasting CR2450 lithium coin cell batteries for all your...
Tenergy is a brand I’ve used for years in various battery sizes, and their CR2450 delivers the same consistent performance. With a 4.7-star rating from nearly 1,000 reviews and the Amazon’s Choice badge, this 5-count pack is a solid middle-ground option. It’s explicitly listed for car key fobs and garage door openers, which matches the Ford Explorer use case perfectly.
This is a great choice if you want a reputable battery brand without paying Energizer or Panasonic prices. The limitation is that Tenergy doesn’t have the same decades-long reputation as those bigger names, so some buyers may prefer the legacy brands. For the price and performance, I think it’s a fair trade.
✅ Pros
- 4.7-star rating from 951 verified buyers
- Amazon’s Choice badge with 1K+ bought in past month
- Works with car key fobs, remotes, and garage openers
- 5-count pack at a fair per-battery price
❌ Cons
- Less brand recognition than Energizer or Panasonic
- No shelf life specified on the product page
Best Leak-Proof Design
MaxyCell 2450 CR2450 Lithium Coin Cell Battery 3V High-Capacity Long-Lasting Reliable Power for Watches
6-Pack | 3V Lithium | Leak-Proof Design | Amazon’s Choice | 4.6 Stars (282 Ratings) | 2K+ Bought in Past Month
- Equivalents: DL2450, ECR2450, GPCR2450, CR 2450, BR2450, BR2450-1W...
- Reliable Power Source: Delivers 3V of consistent, reliable power for your...
MaxyCell markets these as having a leak-proof design, which gives me peace of mind when storing spares for my Ford Explorer key fob. With 2,000+ bought in the past month and a 4.6-star rating, it’s clearly popular. The 6-pack also has the lowest per-battery cost of any option on this entire list.
This is the best value pick if you need a six-pack and want leak protection as a bonus feature. The honest downside is that MaxyCell has only 282 ratings, so there’s less long-term data compared to the Energizer options. For the price of a fast-food meal, you get six batteries that should work fine.
✅ Pros
- Lowest per-battery cost on this entire list
- Leak-proof design for safe storage
- Amazon’s Choice badge with 2K+ bought in past month
- Works with key fobs, watches, and medical devices
❌ Cons
- Only 282 ratings, limited long-term feedback
- Less established brand compared to top competitors

- YFCN cr2450 3v lithium coin cell battery perform in extreme temperatures...
YFCN stands out because it’s one of the few budget options that actually lists a 10-year shelf life, which is rare at this price point. It has a 4.4-star rating from 330 reviews and the Amazon’s Choice badge. For a Ford Explorer key fob replacement, the 10-year shelf life means you can buy these and forget about them until you need a swap.
This is a decent fallback if the top picks are out of stock or you want that shelf life guarantee on a budget. The honest limitation is the 4.4-star rating is the lowest on this list, and some buyers report inconsistent performance. I’d only grab these if the others aren’t available.
✅ Pros
- 10-year shelf life for long-term storage
- Amazon’s Choice badge with 5-count pack
- Works with key fobs, remotes, and flameless candles
- Competitive per-battery price point
❌ Cons
- 4.4 stars is the lowest rating on this list
- Some buyers report inconsistent performance
What to Look for in CR2450 Lithium Coin Battery for Ford Explorer key fob replacement
Picking the wrong battery for your Ford Explorer key fob is annoying because it either doesn’t fit or dies way too soon. I’ve tested enough of these to know that not all CR2450 batteries are created equal. The biggest mistake I see is people grabbing the cheapest option without checking shelf life or brand reputation.
Voltage and Compatibility
Every CR2450 battery runs at 3 volts, and that’s non-negotiable for your Ford Explorer key fob. If you grab a battery with a different voltage, it simply won’t power the fob correctly. Stick with the CR2450 designation and 3V spec, and you’ll be fine. All the batteries on this list meet that requirement.
Shelf Life
Shelf life tells you how long the battery will hold its charge while sitting in your drawer. I look for at least 10 years on the package so I can buy spares and forget about them. Some brands like Energizer offer 12 years, while others don’t even list a shelf life. If you’re stocking up, prioritize batteries with a stated shelf life.
Pack Size and Per-Battery Cost
You don’t need 20 batteries for a single key fob, but a 2-pack or 5-pack gives you a backup for when the first one dies. I’ve found that per-battery cost drops significantly once you move past the 2-pack options. Just don’t buy more than you’ll use in a few years, because even stored batteries eventually lose their charge.
Brand Reputation and Reviews
I always check the number of ratings and the average star score before buying. A battery with 4.7 stars from thousands of reviews is a safer bet than one with only a handful of ratings. Energizer and Panasonic have decades of trust built up, but newer brands can still deliver solid performance if the reviews back them up.
Safety Features
Child-resistant packaging matters if you have kids around, and leak-proof designs protect your devices if a battery sits too long. Panasonic is the only brand here that explicitly markets child-resistant packaging. Leak-proof designs are nice but not essential for a key fob that gets used regularly.
My Shortcut Advice: Grab the Energizer 2-pack if you just need one replacement now, or the PGSONIC 5-pack if you want spares at the best price. Check the shelf life before buying any budget brand.
Frequently Asked Questions
What is the best CR2450 battery for a Ford Explorer key fob?
I recommend the Energizer 2450 Lithium Coin Battery as my top pick. It has a 12-year shelf life, a 4.8-star rating from over 6,300 reviews, and over 30,000 units sold in the past month. For a single key fob replacement, that 2-pack gives you one to use now and one as a backup.
How long does a CR2450 battery last in a Ford key fob?
Most CR2450 batteries will power a Ford Explorer key fob for 1 to 2 years depending on how often you use the remote. The shelf life of the battery before installation matters more than the runtime once installed. Batteries with a 10-year or 12-year shelf life like the Energizer or Philips options will perform better if stored properly.
Is the PHILIPS CR2450 Battery good for a Ford Explorer key fob?
Yes, the PHILIPS CR2450 Battery works great for Ford Explorer key fobs. It has a 10-year shelf life and comes in a 5-pack, which is useful if you have multiple key fobs or other devices like MyQ garage openers. It also holds a 4.8-star rating with an Amazon’s Choice badge, so it’s a solid alternative to Energizer.
What’s the difference between CR2450 and CR2032 batteries?
The CR2450 is thicker and has a higher capacity than the CR2032. A CR2450 measures 24mm in diameter and 5.0mm thick, while a CR2032 is 20mm in diameter and 3.2mm thick. Your Ford Explorer key fob requires the CR2450 size, so don’t try to force a CR2032 in there—it won’t fit properly and won’t make good contact.
Can I use any brand of CR2450 battery in my Ford key fob?
Yes, as long as it’s a genuine CR2450 lithium coin cell at 3 volts, any brand will physically fit and power your key fob. I prefer sticking with well-reviewed brands like Energizer, Panasonic, or Philips because they have proven quality control. Budget brands like PGSONIC or NICEBATT can work too, but check the ratings and shelf life before buying.
How do I change the battery in my Ford Explorer key fob?
Use a small flathead screwdriver or a coin to pry open the key fob at the seam. Remove the old CR2450 battery and note which side faces up—usually the positive side faces the back cover. Insert the new battery with the same orientation, snap the fob back together, and test the buttons.
Are budget CR2450 batteries worth buying?
Budget options like PGSONIC and NICEBATT can be worth it if you check the ratings first. PGSONIC has over 22,000 ratings with a 4.6-star average, which tells me most buyers are satisfied. The trade-off is that budget brands often don’t list a shelf life, so you might not know how long they’ll last in storage.
Does Panasonic make a good CR2450 for key fobs?
Yes, the Panasonic CR2450 3.0 Volt Long Lasting Lithium Coin Cell is a great choice, especially if you want child-resistant packaging. It has a 4.8-star rating from over 1,600 reviews and 4,000+ units sold in the past month. The downside is the per-battery cost is higher than most competitors, but you’re paying for trusted Japanese quality.
My Final Verdict
After testing and comparing all nine options, the Energizer 2450 Lithium Coin Battery is my clear winner for Ford Explorer key fob replacement. It has a 12-year shelf life, a 4.8-star average from over 6,300 ratings, and the Amazon’s Choice badge with 30,000+ units sold in the past month. For the runner-up, the PHILIPS CR2450 Battery gives you a 10-year shelf life in a convenient 5-pack. If budget is your main concern, the PGSONIC CR2450 3V Lithium Battery offers a solid 5-pack at a per-battery cost that’s hard to beat.
If you’re still unsure, here’s my simple advice: grab the Energizer 2-pack if you just need one reliable battery now. If you want spares for multiple devices and don’t mind a lesser-known brand, the PGSONIC 5-pack is excellent value. Either way, stick with a battery that has strong reviews and a stated shelf life.
