Great little battery

Reviewed in the United States on September 26, 2024

I was impressed by how light it is, how fast it charges, and that it has self-protection technology. I used it during camping and power outages with a solar panel and charging system. It went great.

Good replacement

The electric starter on our generator didn’t work because the battery wouldn’t charge. Entered the model number and found this battery. Had to modify the terminals to fit the cables, but the generator started up once connected. Great price and exact fit.

Great ride-on battery replacement

Reviewed in the United States on October 2, 2024

Love the form factor, and size. Plug and play, works well and charges fast. We purchased this to replace the AGM battery on my kid's electric ride on.

Satisfied so far.

Works great until it dies

Reviewed in the United States on August 10, 2024

Update: Bumped from 2 star to 4 stars since seller offered a refund for the batteries

The batteries replaced my lead acid batteries perfectly and they did power my devices when the power was out. However, they died and stopped charging less than a year after putting them in. I purchased them in October 23 and they stopped working August 2024

Great battery, light, and long lasting. Bought 7/24

Reviewed in the United States on September 7, 2024

I put this in my big ecogear rechargeable speaker and am in love with it. I havent had to charge it once yet, I put it in 3 months ago. Total time I have ran the speaker for over 200 hours and it still reads out full bars. Installed perfectly with the slide on clips and came fully sealed no damage.

Very interesting capacity test on this 12v 10Ah battery

Reviewed in the United States on March 25, 2024

First of all I am an electronics hobbyist and I repair electronics as a hobby and have used all types of batteries extensively for a long time. I'm quite familiar with the different chemistries and how to use them and care for them.

In the last week I have purchased 4 LiFePO4 batteries ranging from 6Ah to 20Ah.
This particular 12v 10Ah battery was noticeably heavier than the other 12v 10Ah batteries I received from other brands which struck me as a bit odd. The thought being that either the batteries were more dense meaning more actual internal contents that comprise the battery, or a marketing gimmick to make them feel heavier which might imply a better quality battery. So as always with new storage batteries I set up and ran a full discharge capacity test.

With this one at least the results were surprising. After fully charging the battery I ran a discharge test at 500mA. The result was 11.870Ah. For all intents and purposes, 12Ah. Not sure if this is actually a 12Ah battery mismarked as 10Ah or what but it is what it is. I don't see others getting this capacity from these 10Ah batteries so it may be unusual. Still, pleasantly surprised.

Some people have reported that these batteries were not good for running their computer battery backups and the explanation is simple. These 10Ah batteries are rated for 10A continuous current draw. It is very common for modern desktop PC's to draw more than that. Especially gaming machines with high powered cpu, graphics and power supplies and large monitors, multiple fans etc. While similar sized lead acid batteries might supply significantly more current, in a case like this the BMS in the lithium Phosphate battery recognizes the overload and shuts the battery off. There is no BMS in lead acid batteries so they can give all they have until depleted. I would personally recommend at least a 20A momentary and 15A continuous rated battery for a battery backup. That would allow some surge overhead.

This is my first Nermak LiFePO4 and so far better than so good. How long it lasts and durability are yet to be discovered.

Great Battery

Reviewed in the United States on August 2, 2024

I'm using this battery in 12v, 10ah on my Oldtown 120pdl to run a fish finder. Seems to run forever. I'll fish for 4 to 5 hours a day for 3 days and it barely drops below 13 volts. Very satisfied, light weight and the price was great.

Crazy Cart mod that is soo worth it

Reviewed in the United States on September 27, 2024

I've been running 4 SLA batteries on my crazy cart. Only got about 20-40 mins and 3-5 miles of riding. Switched to these and got 17 miles and the batteries were not even fully charged!
