    • Great price for LiFePO, light weight and highly compatible with existing UPS
Style: 12V 10Ah-2PACK
Due to frequent pwr outage in S.Cal I was looking for replacement batteries for two UPS units. These APC-brand units are over 10 yrs old but are working like champs. The lead acid batteries have been replaced twice and each last roughly 4-5yrs. Initially I was not sure about the charging compatibility b/w Lead Acid and LiFePO, but after reading other ppl's reviews and internet posts, I ordered two battries and surely enough these two units were put to work and test in realtime. Happy to see at one long outage they lasted twice longer (from 3 hrs to 6 hrs) on a relatively low load of 110-130Watts. The battery is fully charged within 1hrs when power is back. It costed a little more than lead one but for the extra $ it's worth. Beside it's half the weight of lead acid ones, when you get older you will appreciate the weight difference. I used LiFePO in RC-controlled airplanes so I love these powerful but lighter one. Seller is very responsive to my concern and timely addressed my inquiry. Highly recommended. ... show more

    • Fantastic Upgrade for My Gate Opener Batteries!
Style: 12V 10Ah-2PACK
These batteries are absolutely amazing! I got them as replacements for the default batteries in my Ghost Controls gate openers, and the difference is night and day. They last significantly longer, perform reliably, and have an impressive cycle lifespan. The built-in BMS is a great feature, ensuring safe and efficient performance. If you're looking for a high-quality LiFePO4 battery for your setup, I highly recommend these! ... show more

    • Update - failed within 1 day
Style: 12V 18Ah
Review Image by RCAddiction RCAddiction
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

    • Purchased for fish finder
Style: 12V 10Ah
I chose this brand for a fish finder setup after reading tons of reviews of different brands on Amazon. This seemed to be the best value and have the highest capacity in the price range. So far it has worked very well. Easy to set up with my fish finder and keeps it powered all day. Make sure you get a LiFePO4 - specific charger for recharging it! ... show more

    • Tough and small!
Style: 12V 10Ah-2PACK
Review Image by Shelly Shelly
I bought these to run seat heater elements on my electric wheelchair. I wanted something separate from the main chair power source, as to not drain the main battery as quickly. I've been using them constantly for months, and can get about 2 days of near constant use before needing a recharge. I accidentally ran one completely down, and thought it may had been damaged, however, it charged up perfectly with no ill effect. I'm super happy with them, and wouldn't hesitate to buy again! ... show more

I always used a reputable lifepo4 specific charger. A few days ago the charger said battery error. I took it off the charger, removed the battery from my boat, and went to bed. Thankfully I did because I came out in the morning to the battery looking like this and over a foot away from where it was sitting. I reached out to the seller/manufacturer due to the battery being 6 months out of warranty. Within hours the company reached out and wanted to make it right. No questions asked. Absolution awesome customer service! I'm thinking this was an isolated event. I will definitely be buying from them again! ... show more

    • Economical, Portable, 12V LiFePO4 Battery for Tire Air Inflator and Other Car Accessories
Style: 12V 20Ah
So far the battery has been excellent, powerful and very useful around the house for everyday uses and also during car trips. The only remaining question is how long the battery could perform like this. After about 6 month of uses, I will update this review to a five star or a three-star rating.

    • Worked very well for APC UPS
Style: 12V 10Ah-2PACK
Bought two to replace a pair of depleted lead-acid batteries in an APC UPS. It's been more than one month now so far it works great, during which we had a short power outage, no issue there. I also tried to turn off the power to calibrate it, but didn't go all the way to empty the battery, it seems it at least doubled capacity of the original lead-acid battery. Great buy. ... show more
