    • 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

    • 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

    • Customer service is incredible. Battery is fantastic.
Style: 12V 10Ah
This is my second battery from Newark. The first one has worked perfectly for years. The second one suddenly died on me after about 7 months. I contacted customer service and they immediately shipped out a replacement that was delivered the same day I contacted them.

    • Early Impressions: A Perfect Fit for the UPS 550
Style: 12V 10Ah
Just a few days into owning this battery, and so far, so good! It’s a perfect match for my UPS 550 (model B0019804U8—the same trusty unit I purchased years ago). Compatibility Check: The UPS recognizes and charges the battery without a hiccup. System Integration: The data cable accurately reads the battery's charge capacity—no issues there. Performance Under Load: The UPS does its thing like a champ, seamlessly drawing power from the battery without errors. Now, onto the one thing I can’t tell you yet: whether this 10Ah battery offers longer run times compared to the 7Ah OEM version. Honestly, I’ve never paid much attention to runtime—I just configure the system to keep my home server running until it gracefully shuts down. (It’s tucked away in a basement closet, doing its thing.) For comparison, I have another UPS 550 with a 6+ year-old OEM battery, but let’s be real—it’s way past its prime and totally untrustworthy for runtime comparisons. The Bottom Line: If you’re looking to save some cash on a battery replacement, this one is a solid option. It’s significantly cheaper than the APC-branded OEM battery and only slightly pricier than the absolute bargain options. That said, I’d think twice about going for the cheapest of the cheap—after all, this is a battery we’re talking about. You don’t want something leaking, exploding, or catching fire! Even if it’s not a “true” 10Ah battery (who really knows?), it’s doing a great job in my book so far. ... show more

    • So far, so good.
Style: 12V 10Ah
I bought this battery to replace the old one in my Ion Pathfinder. For the first time in months I have a full charge. This battery should be an upgrade over the old one, which came with the radio and performed well for years. For the past few months it wouldn't hold its charge and wouldn't charge to more than half capacity. I'm hoping the new battery performs even better, as it has higher capacity and should last longer since its a LIFEPO instead of the old lead acid type. ... show more
