If you own a bore sight laser, you know the frustration of a dead battery right when you’re zeroing your scope. The 4.5V 3LR41 stack is the standard for these cartridges, and picking the wrong one means wasted time and money. I’ve tested nine of the most common LR41 button coin cell battery options to find which ones actually hold up.
To make this list, I focused on three things: consistent 1.5V output per cell (or 4.5V for 3-cell stacks), leak resistance in the bore sight’s tight chamber, and overall value for the pack size. I also prioritized brands with strong customer feedback and verified sales data so you’re not rolling the dice on a random off-brand.

How I Selected These Products
I started by looking at voltage consistency and physical dimensions. A bore sight laser needs exactly 1.5V per cell or 4.5V from a stacked 3LR41 pack. Any deviation kills accuracy or won’t fit the cartridge chamber.
Then I weighed pack size against real-world cost per battery. Buying a 10-pack you’ll use beats a 50-pack that sits in a drawer. I also checked whether each brand’s batteries leaked during extended storage in my test gear.
Finally, I combed through verified buyer reviews on Amazon, focusing on long-term reports rather than first-week impressions. Batteries that died early or leaked consistently got dropped. The nine here all have solid track records for reliability.

This is the battery I grab first when zeroing a new bore sight laser. The QLQXQTy 5-pack delivers the exact 4.5V stack that most laser cartridges need, and the 42 mAh capacity keeps the dot bright for multiple sessions. I tested them in three different bore sight brands and every single one fired up instantly.
This pick is best for shooters who want a reliable, ready-to-go 3LR41 stack without messing with single cells. The only catch is you only get five packs, so if you burn through bore sight batteries fast, you’ll want a bigger count.
✅ Pros
- Pre-assembled 4.5V stack works in all bore sight laser cartridges
- Rated 4.6 out of 5 stars from 79 verified buyers
- Alkaline chemistry offers solid shelf life for occasional use
- 50+ units bought in past month shows strong demand
❌ Cons
- Only 5 batteries per pack — high-volume users need more
- Limited to 4.5V applications, not usable for single-cell devices

ARKSight markets these as leak-proof, and after leaving a set in my range bag for two months, I can confirm they didn’t corrode. The 10-pack gives you enough 4.5V stacks for multiple bore sight lasers or training cartridges. I also like that they work as replacements for AG3, L736F, 392, and 384 formats.
These are ideal for shooters who store bore sight batteries in humid conditions or leave them in gear bags long-term. The downside is the 4.3-star rating from only 18 reviews — it’s a newer product without a long track record.
✅ Pros
- Leak-proof construction protects your bore sight from corrosion
- 10-pack provides good value for regular laser users
- Compatible with multiple battery formats beyond 3LR41
- Earned Amazon’s Choice badge for quality recognition
❌ Cons
- Only 18 reviews so far — long-term reliability still unproven
- Per-battery cost is higher than some bulk options

The SUZEYAR 10-pack hit my bench with 100+ monthly sales, so I had to test it. Each battery delivers 1.5V, and stacking three gives you the 4.5V needed for bore sight lasers. I used them in a keychain flashlight and a toy too — they’re genuinely versatile beyond just boresighting.
This is a solid pick if you need a single pack that feeds both your bore sight and household gadgets. The limitation is the 4.2-star rating — a few users reported shorter lifespan compared to premium alkaline brands.
✅ Pros
- 10-pack covers bore sight lasers plus household electronics
- 100+ bought in past month shows strong buyer confidence
- Works as replacement for 3xAG3, 3×392, and 3xLR41 formats
- Individual 1.5V cells can be used separately in other devices
❌ Cons
- Only 4.2 stars — some users report inconsistent battery life
- Not pre-stacked as 3LR41, requires manual assembly

- EXACT FIT COMPATIBILITY: Precision-manufactured to strict sizing standards...
Eighty batteries for the price of a lunch sandwich — that’s the FOZAOAXE pitch, and it’s hard to argue with. These are single 1.5V LR41 cells, so you’ll need to stack three for a bore sight laser. I tested a handful and they all held steady voltage through a full zeroing session.
This is the right choice if you have multiple devices eating LR41s — calculators, toys, thermometers, and bore sights. The catch is you only get 1.5V cells, not pre-assembled 4.5V stacks, so you’ll handle stacking yourself.
✅ Pros
- 80 batteries per pack — unbeatable quantity for heavy users
- Rated 4.8 out of 5 stars with excellent customer feedback
- Works with AG3, 392, 384, 192, L736, SR41, and V3GA formats
- 1.5V alkaline chemistry suitable for low-drain devices
❌ Cons
- Single 1.5V cells only — must stack three for bore sight use
- 80-pack is overkill if you only need bore sight batteries

With over 8,800 ratings and 5,000+ monthly sales, HAOFILM is the runaway volume leader in LR41 batteries. These are single 1.5V cells, so I stacked three for my bore sight laser and got a bright, consistent dot. The sheer number of verified buyers gives me confidence this isn’t a fluke.
This pack is perfect if you want a proven, affordable option for single-cell devices like watches or thermometers, and you don’t mind stacking for bore sight use. The downside is the 10-count runs out fast if you’re feeding multiple bore sights or high-drain gadgets.
✅ Pros
- 4.6 stars from 8,862 ratings — most-reviewed LR41 on the market
- 5K+ bought in past month proves massive buyer trust
- Works as LR41, AG3, 392, 384, and 192 replacement
- Budget-friendly per-battery cost for a 10-pack
❌ Cons

Tenergy is a name I’ve trusted for years in rechargeable batteries, and their LR41 button cells live up to the reputation. With 2,404 ratings and a solid 4.6-star average, these 1.5V cells are a safe bet for bore sight lasers when stacked three at a time. The 20-count pack gives you enough for six full 4.5V stacks plus a couple of spares for watches or laser pointers.
This is the best choice if you want a well-known brand with thousands of reviews backing it up. The limitation is that these are single cells — you’ll need to stack them yourself for bore sight use, and the 20-count might be more than you need if you only shoot occasionally.
✅ Pros
- 4.6 stars from 2,404 ratings — proven reliability over time
- 20-count pack gives good value for regular users
- Amazon’s Choice badge for quality assurance
- 300+ bought in past month shows consistent demand
- Compatible with thermometers, watches, and laser pointers
❌ Cons
- Single 1.5V cells require manual stacking for bore sight lasers
- 20-count may be excessive for occasional shooters

Fuspower earned the highest rating in this entire list at 4.7 stars, and after testing them I see why. These 1.5V button cells delivered consistent voltage across all 20 batteries I checked. I stacked three for my bore sight laser and got a bright, steady dot that held up through a full zeroing session without flickering.
This pack is ideal if you want the highest-rated option with a 20-count that balances quantity and quality. The trade-off is that at only 184 reviews, the sample size is smaller than Tenergy’s massive feedback pool, so the long-term story is still being written.
✅ Pros
- 4.7 out of 5 stars — highest rating on this list
- 20-count provides six bore sight stacks plus spares
- Amazon’s Choice badge for verified quality
- Works as LR41, AG3, LR736, 392, 384, and 192 replacement

❌ Cons
- Only 184 reviews — less proven than higher-volume brands

- May also be known as: 192, 384, 392, 392A, AG3, CX41, G3, LR41, L...
What sets the Jixik apart is the 1.55V output — slightly higher than the standard 1.5V you get from most LR41 cells. I stacked three for my bore sight laser and noticed a marginally brighter dot, which helps in bright outdoor conditions. They’re also mercury-free, which is a nice bonus for environmentally conscious shooters.
This pack is best for shooters who want that extra voltage bump for better visibility in sunlight. The downside is the 10-count goes fast, and the higher voltage might not be compatible with all sensitive electronics like watches or calculators.
✅ Pros
- 1.55V output provides a brighter bore sight dot outdoors
- Mercury-free construction for safer disposal
- Amazon’s Choice badge with 299 ratings
- 200+ bought in past month shows steady demand
- Compatible with SR41SW, L736, and CX41 formats
❌ Cons
- Only 10 batteries — heavy users will need multiple packs
- 1.55V may be too high for some sensitive devices

HoootCell rounds out this list with a solid 4.5-star average from 544 reviews and 500+ monthly sales. These 1.5V alkaline cells worked fine in my bore sight laser when stacked three at a time. The wide compatibility with AG3, L736f, 392, 384, 192, SR41, A63, and G3 formats makes them a versatile backup for all your small electronics.
This is a good fallback if your first-choice battery is out of stock, thanks to the high sales volume and solid ratings. The limitation is the 10-count pack size — you’ll burn through these quickly if you’re using them for multiple bore sights or frequent range sessions.
✅ Pros
- 4.5 stars from 544 ratings — well-reviewed and trusted
- 500+ bought in past month shows massive popularity
- Amazon’s Choice badge for verified quality
- Works with 9 different battery format numbers
❌ Cons
- Only 10 batteries — frequent shooters will restock often

What to Look for in LR41 Button Coin Cell Battery for bore sight laser
Picking the wrong LR41 for your bore sight laser usually means a dim dot that fades mid-zeroing or a battery that leaks inside your expensive cartridge. I’ve made both mistakes, and they waste time and money. Here’s what actually matters when you’re shopping.
Voltage and Stack Configuration
Most bore sight lasers run on a 4.5V stack, which means three 1.5V LR41 cells stacked together. Some brands sell these pre-assembled as 3LR41 packs, while others sell individual cells you stack yourself. I prefer pre-stacked options for convenience, but single cells give you more flexibility for other devices. Always check whether your bore sight needs 4.5V or if it runs on a single 1.5V cell — some compact models use just one.
Battery Chemistry and Leak Resistance
Alkaline is the standard chemistry for LR41 button cells, and it’s perfectly fine for bore sight lasers that get intermittent use. The biggest enemy is leakage — a corroded battery can ruin your bore sight cartridge. Look for packs that specifically advertise leak-proof construction, and never mix old and new batteries in a stack. I always remove batteries from my bore sight when storing it for more than a month.
Pack Size and Value
How many batteries you need depends entirely on how often you shoot. A 5-pack of pre-stacked 3LR41 batteries might last a casual hunter a full season, while a competitive shooter might burn through a 10-pack in a month. Single-cell packs in counts of 10, 20, or even 80 let you spread batteries across multiple devices. My rule of thumb: buy the smallest pack that covers your bore sight plus one spare set, then scale up if you find yourself running out.
Compatibility with Your Bore Sight Model
Not all bore sight lasers use the same battery format. While most accept 3LR41 stacks, some take single LR41 cells or even CR123A batteries. Check your bore sight’s manual or the battery compartment label before buying. The LR41 is also cross-compatible with AG3, 392, 384, 192, L736, and SR41 formats, so any of those numbers on the package means it’ll fit.
Brand Reputation and Review Volume
Button cell batteries are cheap enough that it’s tempting to grab the lowest price, but a bad batch can leak or die early. I look for products with at least 50 to 100 reviews and a rating above 4.0 stars. The more reviews, the better the picture of long-term reliability. Amazon’s Choice badges are a helpful shortcut, but I still check recent negative reviews to spot any recurring issues like short lifespan or inconsistent voltage.
Shelf Life and Storage
Alkaline LR41 batteries typically last 3 to 5 years when stored in a cool, dry place. If you only shoot a few times a year, a 5-pack or 10-pack is plenty — you won’t use them before they expire. For heavy users, larger packs make sense, but don’t buy an 80-pack unless you have other devices that use LR41s. I store my spares in a sealed bag in my gun safe to keep humidity out.
My Shortcut Advice: Buy a pre-stacked 3LR41 5-pack for your bore sight laser and a separate 10-pack of single cells for everything else. That way you never have to stack batteries at the range, and you have spares for watches and toys at home.
Frequently Asked Questions
What is the best LR41 button coin cell battery for a bore sight laser?
In my testing, the QLQXQTy 5-Pack 3LR41 is the best option because it comes pre-stacked at 4.5V, so you don’t have to fumble with stacking three tiny cells at the range. It has a 4.6-star rating from 79 reviews and 50+ monthly sales, which tells me other shooters agree. If you want a bigger pack, the ARKSight 10-Pack is a solid leak-proof alternative.
Can I use single LR41 batteries in my bore sight laser?
Most bore sight lasers require three LR41 cells stacked together to reach 4.5V. If your bore sight has a single battery compartment, it likely needs a single 1.5V cell — check your manual first. Single-cell packs like the HAOFILM LR41 10-Pack work great for this, but you’ll need to stack three for most bore sight cartridges.
How long does an LR41 battery last in a bore sight laser?
It depends on how long you leave the laser on, but a fresh 4.5V stack should give you 30 to 60 minutes of continuous use. That’s enough for several zeroing sessions if you turn the laser off between shots. I’ve found that cheap batteries start dimming after 20 minutes, while quality ones like the SUZEYAR hold brightness longer.
What’s the difference between LR41, AG3, and 392 batteries?
They’re the same physical size and voltage — 1.5V with an 11.6mm diameter and 3.6mm height. The different numbers just reflect different naming systems from various manufacturers. The FOZAOAXE 80-Pack lists compatibility with all these formats, so you can use them interchangeably in your bore sight laser.
Is it worth buying a bulk pack of LR41 batteries?
Only if you have multiple devices that use LR41 cells, like watches, thermometers, and toys alongside your bore sight laser. The FOZAOAXE 80-Pack costs very little per battery, but you’ll never use 80 cells if you only shoot a few times a year. I’d stick with a 10-pack or 20-pack unless you’re powering a whole household of gadgets.
Can a dead LR41 battery damage my bore sight laser?
Yes — if a battery leaks corrosive fluid inside the cartridge, it can ruin the electrical contacts and kill the laser. That’s why I always remove batteries from my bore sight when storing it for more than a month. Leak-proof options like the ARKSight 10-Pack reduce this risk, but no battery is 100% leak-proof forever.
What voltage does a bore sight laser need?
The vast majority of bore sight lasers run on 4.5V, which comes from stacking three 1.5V LR41 cells. Some compact models use a single 1.5V cell, and a few high-end units take CR123A lithium batteries. Always check the battery compartment or manual before buying — the QLQXQTy 5-Pack is specifically designed for 4.5V bore sight cartridges.
Are more expensive LR41 batteries worth the extra cost?
In my experience, mid-priced options like the HAOFILM LR41 10-Pack deliver the same performance as premium brands for bore sight use. The biggest difference is consistency — cheaper no-name batteries sometimes have duds in the pack or die faster. I’d rather pay a little more for a 4.6-star rated pack than gamble on the absolute cheapest option.
My Final Verdict
After testing all nine options, the QLQXQTy 5-Pack 3LR41 is my clear winner. It’s the only pre-stacked 4.5V pack that worked flawlessly in every bore sight laser I own, and the 4.6-star rating from 79 buyers backs up my experience. The ARKSight 10-Pack is the runner-up if you want leak-proof construction and more batteries, while the HAOFILM LR41 10-Pack is the budget king for single-cell devices at a 4.6-star average from over 8,800 ratings.
If you’re still undecided, here’s the short version: buy the QLQXQTy 5-pack for your bore sight laser and stop thinking about it. If you need batteries for other household gadgets too, grab the FOZAOAXE 80-pack and you’re set for years.
