This small lithium battery has performed very well through six fishing outings supplying Power to my Humminbird Helix 5 fish finder. It holds the charge through 6 hours on the water. I highly recommend this light weight battery.

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.

Battery worked great at the start, we followed charging instructions but did not last more than a month. Now it won’t hold a charge. It’s a dead battery that got very little use out of it. However, customer service was great, warranty was honored and a new one was sent out. I will provide an update on the next battery to see if this one lasts longer.

I’d recommend against usage for “legacy” UPS lead acid battery replacement, specifically the common case of quantity 4 or 2 battery systems. These usually are setup with the batteries in series (4x12v = 48v, 2x12v=24v). You are likely better off throwing the legacy lead acid battery UPS away, and buying a lifepo4 based UPS. Even the Lifepo4 portable batteries like the power 1000 have UPS capability. The ups devices that start with a lifepo4 energy source usually have passive and active cooling for the battery array, in addition to the inverter components. There are a few problems with using these in a legacy lead acid battery UPS: 1. The continuous output current is far lower than lead acid batteries. The typical Lifepo4 compatible battery option is rated at 10amp continuous. So, in a 4 battery series system, you’ll get at most about 135w continuous output per battery - so about 500watt max. You won’t get anything near the potential needed in common 1000w, 1500w, and 2000w ups. 2. The BMS present in the lifepo4 batteries generally needs at least exposed passive cooling, or even active cooling. These are enclosed package batteries, so cooling is limited at best. 3. With 4 12v lifepo4 batteries in series, you’d basically need another BMS to manage the 4 batteries, or the discharge and charge levels between batteries becomes imbalanced. 4. The charging circuit will not fully charge lifepo4 batteries, in most cases. Lead acid vs. lifepo4 have different max voltage levels. 5. The legacy ups doesn’t know the proper estimated runtime or charge level of lifepo4 batteries. This is a relatively minor issue compared to above. Technically, a 48v lifepo4 pack that fits most UPS battery compartments could be built to handle several of the issues above. As an experiment, I fully charged up 4 of these individually outside a UPS, then installed them in the ups. Verified the output of the pack was approx 55.8v. The charge/discharge circuit ”popped” with the telltale electronics burning smell, with smoke, when a 200w load AC power fail test was triggered. These batteries may be ok for some cases, like the single battery backup common to home alarm system panels.

I bought these for my Cyberpower UPS. They don't fit with the plate that goes between the batteries. I used wooden blocks to make the space between the cells to fit my UPS, but these Nermak batteries are a couple of mm taller than the SLA batteries that they are replacing. This was enough that I had to remove the plate in my unit. The USP is operating normally and isn't getter hotter than before. I'm confident that these cells will last much longer than the 3 years that I got from the last cells that I had in there. Also, the cells were within a few hundredths voltage from each other when they arrived, so I didn't have to balance them before installation. I may inspect them in a few months to verify that all continues to be well.
