Review: I've had my Cyberpower 1500PFCLCD UPS for about 4 years now. I noticed that despite no indicated internal battery problems, the UPS would fail during brownouts or other equipment being turned on. It did not use to do that. To validate, when I have my UPS connected to the wall (with zero loads plugged into it) and I disconnect the AC mains from the UPS, the unit would insta-power off instead of staying on (and running from battery power). This is the classic symptom of a dead internal battery! Anyways, Replacing the battery was straightforward. I picked up a pair of these Expertpower EXP1290's instead of shelling out more than double for the Cyberpower (supposedly) original battery. In reality, the 'original' batteries are Leoch DJW12-9.0's. These batteries arrived about 3/4 charged (~12.74 VOC), in a well protected package. Delivery was quick (2 days). After replacement, the UPS now behaves normally and correctly stays on / runs from battery when it's disconnected. No error messages or other silliness. Also, for what it's worth these terminals on this battery actually fit the internal connectors 'better' than the original. Your milege may vary on that tho, I'm sure it's game of sub-millimeters. While I cant yet confirm if these batteries will last as long as the original; their value is spectacular when compared to the original batteries. Operation looks good. I will update this review in the next few months if anything untowards occurs -- which I doubt. Highly recommended!
Review: When Craftsman designed their Battery Start Lawnmower in the 1990's, they supplied a $90.00 small battery pack to start it with. It was 6 small D sized NiCad batteries inside a box that was used to start the mower with. The previous owner didn't want to spend $90.00 on a replacement battery that would go bad in a short time. Over the years the NiCad batteries deteriorated, and that is why I got my lawnmower for free from the sidewalk in my neighborhood. I modified the battery chamber to accept a small Walmart small lead acid battery, but they too seem to go bad in 2-3 years. I bought this 12 volt 9 Ah LiFePo battery to see if it will last longer than 2-3 years. It starts my mower much better than the Walmart lead acid battery, and now I have a fully functional 30+ year old lawnmower again. The lawnmower magneto recharges the battery when it is running, and I haven't had to charge the new LiFePo battery in between uses of the lawnmower at all. The onboard BMS system inside the battery manages the charging routine when the mower is running and it seems to recharge it well. Hopefully this battery will make my vintage lawnmower work for me for many more years. I am building a padded steel box to secure this new LiFePo battery to the mower deck because it is too large to go into the original small battery compartment of the mower deck. Stay tuned to see just how long this new battery technology battery lasts, but for now it is working very well.

## Questions & Answers

**Q: what are the dimensions**
A: Product Dimensions: 5.9 x 2.5 x 3.7 inches

**Q: What is your recommended inital charge time for this battery and general care recommendations?**
A: Lead acid batteries such as these do NOT have memory issues as do lithium or NiCd batteries.  You should avoid a complete discharge of lead acid batteries , as each time you run them down completely you shorten their life considerably.  Same as car batteries which are also lead acid...   Never, if you can avoid it, discharge them completely.

**Q: How much does this weigh?**
A: It weighs roughly 1.5 - 2 pounds.

**Q: Will these batteries work in an apc ups?**
A: This battery has about the most capacity available in this size and a lot of good specs as to charge and discharge rates. I think that makes it more likely to work in random UPS's than average. But there are tricky problems that could make it not work in some UPS's. And of course its size must fit in the UPS case.
