  • Great little battery
Style: 12V 10Ah
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
Style: 12V 10Ah
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.

  • Update - failed within 1 day
Style: 12V 18Ah
Update 4 days later, 10/11/2024 Well...this did not work out. The battery arrived and was installed on Monday, just before Hurricane Milton struck Wednesday night. After a1/2 second test crank (which was fine), the battery was connected to a new LiFePo4 battery charger designed for this battery chemistry. The charger itself may be suspect, as the battery would not accept a charge. The charger displayed a fault mode after a few hours. I then connected it to a known good charger. After a charge of several hours at 2amps, the charger had to be disconnected as we prepped for the storm. A quick check on Tuesday (the next day) found that the generator would not start. Did not have time to do diagnostics with the storm coming. Had to pull-start the generator after we lost power Wednesday evening. Did diagnostics today, Friday 10/11. No problem with the starter motor, as it started immediately with my portable jumper pack. The Nermark battery showed less than 10V on my DVM. Both chargers displayed a battery fault, and were unable to charge the battery above 10.3V. It's possible there was an issue with the built-in BMS (Battery Management System), but I don't know. It's getting returned once Whole Foods is open again. Original Review 10/7/2024 Very simple installation to remove the old sealed lead acid 12-18 battery and replace it with this one. I have been using LiFePo4 batteries in my RC aircraft for over 20 years and I'm glad that this battery is available to replace the typical unreliable lead acid battery that is used as a starter in portable equipment. I took the opportunity to install the terminal rings and cable for the appropriate 3 amp charger and even without completing the charge, did a quick test start on my generator. I hope it will last several years, as this generator is only used for hurricane emergencies. However, I have batteries of this chemistry that are over 20 years old and still hold 80% or more of their charge. I will report back and update this review in the event that there are any failures, or possibly great news to continue to report years from now. ... show more

  • Works great until it dies
Style: 12V 10Ah-2PACK
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 ... show more

  • Great ride-on battery replacement
Style: 12V 16Ah
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.

  • Great battery, light, and long lasting. Bought 7/24
Style: 12V 10Ah
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.

  • They work better than lead acid batteries!
Style: 12V 10Ah-2PACK
After Covid, my wife needed a way to travel in a public school from class to class. We chose the go-go was the right fit for that job. I changed out the second set of SLA batteries because they didn’t last long. She loved the quick charge and performance of the new LiFePo’s.
