Pretty Awesome on my review.

So what kind of loser writes battery reviews? This one!I purchased a 4-pack for LED lights I like to use. These were the most powerful lithium batteries I could find at 1200mAh.They arrived well packaged and each battery had a nice rubber cap to prevent short circuits. Love it.They are extremely well manufactured. Slightly larger than standard--yes--so beware.But they are damned near perfect.When I hooked them up to my 9v LED, they cast the brightest light I have seen from it. Perhaps it is…

Pros

Not sure how long this will last but so far so good.

Cons

They didn't even last 6 months. I was woken up at 3am from smoke detectors going off.

Double capacity! - my new review

I have an electronic door lock that is used heavily. I usually change the battery every 6 months. Love the fact that these are double the capacity. No issues so far. Hopefully, they'll last a year.

Pros

Household Batteries

Cons

Could potentially drain quickly if not used carefully or if the device is left on for too long

Smoke detectors best in my review

Got these 10 year batteries for smoke alarms.I only wish they said 10 year on the battery itself, rather than just the plastic packaging.

Pros

Great not to have to worry about changing for years to come.

Cons

Requires a compatible device that supports 9V batteries, which may limit its usability

didn't last on shelf for 2 years and too big for lots of stuff

I bought these in 2018 and they could not drive .3 amps at short circuit after staying on shelf until 11/2020. They are too big for some equipment. I realized they are not re-chargeable. Stay away from these , not worth the money.

Pros

These are for our smoke detectors and I'll let you know in 10 years if they last as advertised.

Cons

Li-Ion batteries have a higher risk of overheating and exploding compared to other battery types

Twice as good as Alkaline?

I bought these Lithium batteries for smoke detectors around the house. Since I have a battery tester ( a real one not one that puts a small load on the battery and measures how much the voltage drops), I decided to measure the capacity compared to a top-of-the-line Alkaline battery. This test measures how long a battery will last while it is supplying power to a resistive load. The attached chart shows the result. The capacity of the batteries, measured in milliampere-hours is on the…

Pros

Health & Household

Cons

Requires a specific charger in order to charge, adding an additional expense

Non-rounded corners may cause fit issues

Seems like a decent battery however the battery body does not have rounded edges like most have. This created issues with several of our devices that the cover would not snap fully engaged.

Pros

The product was as advertised as arrived as promised; actually earlier than promised!

Cons

May not be compatible with all types of smoke detectors or fire alarms

Posted July 12, 2023Updated July 12, 2023

Updated: lasted less than 2 years

Update 9/12/2020:Lasted less than 2 years in smoke detectors. Not sure it is worth the extra cost.A little pricey compared to standard 9V batteries. Obviously it will be some time before I find out if it is worth the extra.It is important to note that these batteries are a little larger than the standard. It took some doing, but I was able to get them installed into my smoke detectors. It will take a bit of finesse but they will fit.

Pros

Perfect for our smoke alarms. Should last a few years.

Cons

Non-rechargeable, which could be inconvenient and costly in the long run

Poor Quality Didn't last as long as normal batteries

Bought these for my smoke detectors in June 2018, they are now failing one after the other, I question weather they are even Lithium. Poor quality, don't waste your money!

Pros

Very good transaction--Great Battery

Cons

Heavy and bulky, making them difficult to store or transport

4 Years and counting

With 8 smoke detectors and 2 CO detectors in the house, I got tired of the batteries needing changing frequently and definitely loathe the midnight chirping (why do they only chirp in the middle of the night?!?!?). This is actually a belated review as I first purchased these batteries 4 years ago. My first smoke detector started chirping last night, 4 years after my initial purchase. So, here I am ordering a new set. I plan to replace all of the batteries at once now that the first detector has

Pros

Used it for my son's remote control cars...

Cons

Could potentially damage devices that require a lower voltage output

Posted June 29, 2023Updated June 29, 2023

i purchased a 4 pacl on 9/29/2019 and one just dies in my smoke alarm

I should be reimbursed for this one, hopefully the other 3 don't start going bad, I hope the seller sees this and makes good on the purchase

Pros

Long-Lasting Performance

Cons

Not as widely marketed as other battery types, making it difficult to find a replacement

Posted June 28, 2023Updated June 28, 2023

did not work perfectly with

the infographic shows that it works perfectly with a wide array of devices including an infrared thermometer. well it didnt work perfectly with my infrared thermometer or my smoke alarm because the battery is a few mils larger than a normal 9v. it didnt fit in my smoke alarm at all, and i couldnt really close the battery door on my infrared thermometer. it did kindof close for a bit but then the door popped off snapping the hinge. :( :( :(

Pros

We sold our house and I bought them for the new owners to put in their smoke detectors.

Cons

Might not last as long as advertised

Posted June 25, 2023Updated June 25, 2023

It's definitely larger than other 9V size batteries

Bought these Enegitech 9V batteries for smoke detectors; found them are too big to fit in the 9V battery chamber, WTH?! What is the point of these bigger capacity 9V battery that don't even fit in devices?! Serious? I would never recommend this battery and want my money back.

Pros
