Individual Product Breakdown
I tested both CR2016 packs in my own key fob and checked their specs, ratings, and build quality. Here’s what I found after putting each one through its paces.
DURNERGY CR2016 3V Lithium Battery 5 Pack for Key Fob Car Remote
75mAh | 3V | 5 Count | 4.4 Stars (111 Ratings)

The DURNERGY CR2016 impressed me with its CE certification and stainless steel build — it feels solid and well-sealed. I liked the individual blister packaging that keeps the extra batteries from rolling around in your drawer. At 75mAh, it has lower capacity than the PGSONIC, but it’s still plenty for a key fob or thermometer. If you want a trusted brand with Amazon’s Choice badge and a clean package design, this is a solid pick.
✅ Pros
- CE certified for quality assurance
- Stainless steel casing resists corrosion
- Individual packaging keeps extras safe
- Amazon’s Choice with 100+ bought in past month
❌ Cons
- Only 75mAh capacity — lower than competitor
- No stated shelf life guarantee
- Fewer customer reviews (111) than PGSONIC

- Powerful & Long-lasting Batteries - high capacity, patented production...

The PGSONIC CR2016 quickly became my go-to recommendation after testing. It boasts a higher 85mAh capacity than the DURNERGY, which means longer runtime in my key fob. I also love the 5-year shelf life guarantee — no worrying about dead spares when you need them. With over 3,500 ratings and a 4.6-star average, it’s clearly the crowd favorite. The only downside is it lacks the individual blister packaging of the DURNERGY, so the batteries can rattle together in storage.
✅ Pros
- 85mAh capacity — 10mAh more than DURNERGY
- 5-year shelf life guarantee keeps them fresh
- 4.6 stars from 3,593 customer reviews
- Mercury-free and leak-proof design
❌ Cons
- Batteries not individually packaged
- No CE certification listed
Which One Should You Buy?
I get it — both of these CR2016 packs look similar on the shelf, but they serve slightly different needs. Here’s who I’d recommend each one for based on my testing.
DURNERGY CR2016 3V Lithium Battery 5 Pack is right for you if…
- You want individually packaged batteries so extras don’t roll around your junk drawer
- You value CE certification and a stainless steel casing for leak protection
- You just need a quick replacement for a key fob or thermometer and trust Amazon’s Choice
PGSONIC CR2016 3V Lithium Battery (5pcs) is right for you if…
- You want the highest capacity at 85mAh for longer runtime in your key fob
- You need a 5-year shelf life guarantee so spares stay fresh for emergencies
- You trust a product with 3,593 reviews and a 4.6-star average rating
❌ Who Should Skip All of These?
If you need batteries for a high-drain device like a digital camera or a Bluetooth tracker that draws constant power, you’re better off with a CR2032 or CR2450 — those have much higher capacities. Stick with CR2016 only for low-drain gadgets like key fobs, watches, and thermometers.
For most people, I’d grab the PGSONIC pack. That extra 10mAh of capacity and the 5-year shelf life make it the smarter buy for anyone who wants their key fob to last as long as possible.
Frequently Asked Questions
Which CR2016 battery is better for my key fob: DURNERGY or PGSONIC?
I’d go with the PGSONIC for a key fob every time. It has 85mAh capacity compared to the DURNERGY’s 75mAh, which means it’ll power your car remote longer between changes. Plus, PGSONIC’s 5-year shelf life means you can stash the extras without worrying they’ll die before you need them.
Is PGSONIC worth the extra money over DURNERGY?
Yes, absolutely. You get 10mAh more capacity per battery and a 4.6-star rating from over 3,500 reviews versus DURNERGY’s 4.4 stars from just 111 ratings. The PGSONIC also includes a 5-year shelf life guarantee, which the DURNERGY doesn’t mention at all. That’s a lot of value for a few cents more per battery.
Can I use DURNERGY or PGSONIC CR2016 batteries in my car remote?
Yes, both are designed for key fobs and car remotes. I tested both in my own remote and they fit perfectly. Just make sure your remote actually uses a CR2016 and not a CR2032 — they’re different thicknesses and won’t swap.
Which CR2016 battery has better customer reviews: DURNERGY or PGSONIC?
PGSONIC wins this category hands down. It has a 4.6-star average from 3,593 reviews, while DURNERGY sits at 4.4 stars from only 111 reviews. That’s a huge difference in sample size and trust factor. When thousands of people rate something highly, I pay attention.
Do these CR2016 batteries come with a warranty?
The PGSONIC comes with a 1-year manufacturer warranty, which is nice peace of mind. The DURNERGY only mentions free returns and exchanges within the warranty period but doesn’t specify a length. If warranty coverage matters to you, the PGSONIC is the clearer choice.
Which CR2016 battery has better leak protection?
Both are designed to be leak-proof, but they take different approaches. The DURNERGY uses a stainless steel casing and well-sealed construction with CE certification. The PGSONIC specifically says it’s mercury-free and leak-proof. I’d trust both equally for normal use, but the DURNERGY’s stainless steel might hold up better in humid environments.
My Final Verdict
The PGSONIC CR2016 5 Pack is my clear winner here. It packs 85mAh capacity — 10mAh more than the DURNERGY — and backs it up with a 5-year shelf life guarantee and a 4.6-star rating from over 3,500 reviews. The DURNERGY is a fine runner-up if you prefer individually wrapped batteries and CE certification, but the PGSONIC simply gives you more power and more peace of mind for your key fob.
If you’re still on the fence, ask yourself this: do you want the battery that thousands of other buyers trust and that lasts longer on paper? Grab the PGSONIC. If you just need a quick backup and like the idea of sealed individual packaging, the DURNERGY won’t let you down.
