  • Maybe this will last a lifetime.
Style: 12V 10Ah
I use three of these to power my electric push mower that refuses to die. It doesn't get a LOT of use anymore, but for trimming around the edges and on a small hill the riding mower can't get to, it's still essential. They stopped making this mower several years ago, but I can still get batteries for it. It's a plastic shell the size of a car battery with three SLA inside. Last price $150. this is the third set of batteries i've gotten for this mower. The SLA's last a LONG time (5-6 years), but demand some attention so they don't go completely dead during the off season. I was a little concerned about whether these would handle the current draw required for thick grass, but they seem to be doing just fine. the new charger I got says it can be constantly connected, so I'm hoping these new ones won't need quite a much maintenance attention as the old. at half the weight, it will be a LOT easier to charge in the house where it's protected from temp extremes and be easier to keep an eye on. ... show more

  • 2 out of 4 failed, manufacturer replaced in 3 days!
Style: 12V 10Ah
So ive been using these for about 3 years in some UPS units. Been working fine for the most part but it seems like the non-digital UPS units like the ones that sit on the floor will overload these batteries and cause damage to the BMS or something. I had 2 batteries die, one the voltage just dipped down to 2.3v and another the BMS got so hit it was melting the plastic on top and triggering a cut off. I brought up my issues to nermak on amazon and they shipped out 2 replacements immediately, got them a few days later. Very quick response and zero hassle, which is what all manufacturers/sellers should do. Using these in digitally controlled UPS units like 1000va+ (basically the towers) seem to have no issues over long periods, but APC doesnt recognize the chemistry difference at all and wont fully use the whole capacity of the battery. So im just gonna put all these into a batbox with a inverter and put the lead acids back in. Over all good battery, and good support. Im sure with everything working correctly these will last many years. I think i just got a couple duds lol. ... show more

  • Compatible with 12v Ride on Jeep
Style: 12V 10Ah
Great replacement for 12v Ride on jeep. The original battery was a 12v lead acid battery 7.2amp and BCP wanted $75 with no guarantee. Imagine my shock when I found this 2 pack of lithium batteries with a 30 day return policy for half the price. As a mom of 4 kids things rarely go as planned so my expectations were low . The last thing I wanted to do was go through the return process for an Inaccurate web description but I figured it was worth the try . Turns out they are actually compatible ! Not only is the battery a perfect fit but it took less then 8 hours to charge and we’ve already had twice the play time as the original battery. even if we only get a few months out of the battery we have the second battery as a back up and still …. saved money. I did have to watch a you tube video to learn how to replace battery but it was such an easy experience I feel unstoppable now ... show more

Updating because of crazy good customer service. They replaced the malfu ctioning battery and shipped it overnight. I am floored. I will leave another review after a few months of running the battery! For reference, the original battery never took a charge and showed 0V. The new battery is running mint on Day 1. ... show more

  • Works great until it doesn't
Style: 12V 10Ah
Basically what the title says, maybe I got a lemon. Went with this over a more traditional AGM battery to power my small Garmin striker 4 fishfinder. Didn't last 2 years and at best a couple dozen cycles/recharges. It simply stopped working mid fishing trip. I thought the lithium battery would hold up better than the 6-7 year old AGM that gets neglected in the corner of my garage for 6 months at a time. Guess not. ... show more

  • 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
