ExpertPower 12V 10Ah Lithium LiFePO4 Deep Cycle Rechargeable Battery - Ideal for Solar Panels, Golf Carts, and Other High-Drain Devices

Fredrick W.: I don't know yet about the longevity of this battery. The lead acid battery that it replaced had lasted for several years.
This new battery is about a third of the weight of the old one.
It was a direct replacement for the size/fit of the old one.
It fit right in and the UPS went on line with no problems.

S. W. Norwood: I bought this for my small sailboat to power the depth sounder. I had tried another brand, same size, dimensions, weight, etc. from another vendor, and the other vendor's battery was DOA and could not be resuscitated. The other vendor assumed I had cross-wired the charger and sent me another charger. Problems not solved. Then they sent me a replacement battery under their 30-day warranty. Same problem, probably coming from the same faulty batch. So, I bought THIS battery and it works perfectly as expected.

T. Meados: Lightweight, compact, doing what it should so far.
Bonding material on top of battery had linked up with the underside of the terminals preventing the blade connectors impossible to get on. Had to file this material away to fix.
Otherwise, happy with the product.

itpmguru: Review for 9ah- I had purchased a couple of these as supposedly "refurbished" for a small APC UPS. Used an external charger to ensure they were at full capacity and let them set overnight and repeated. Put them in my UPS and after the first self-test, UPS shut off. Pulled to see what happened and one battery was still showing 13.8 and the other one showed 5 volts. Took them back to the external charger and the one topped off at 14.4 just fine. The other one topped off at 14.4, registered as "full". When I removed the charger, it immediately started dropping and was about 10v and determined something was wrong. The other one I have is still fine, at this point.

"IF" the quality control on these batterie is good,, then why are there so many refurbs available? "IF" they hold up, they would be good for a smaller UPS and should last longer as in most APC SUA there is a way to adjust the float voltage so they are properly charged and not over charged. Gets to be a pain (and waste) to replace batteries every couple of years, that is why I was going to try these instead.

I see the possibilities with these batteries lasting longer than SLA, but I am not convinced at this...

just being Frank: My aging Celestron power tank used to drive my night-time 'scopes was flagging. Too much extended use maybe, maybe casual maintenance, but all the same the old tank was now a puddle.

Pros: LiFePo4 batts run until they collapse, providing juice well beyond the 50% lead-acid batts.
This was a direct replacement size-wise, with a 30% boost in sustained amps. Make sure you measure the bay intending to receive this new batt.

LiFePo4 batts provide up to 80% energy, but then they quit suddenly.

LifePo4 batts charge rapidly, and far more often than their lead-acid counterparts.
This batt is considerably LIGHTER in weight making it easier to cart around in the dark.

Note: LiFePo4 batts require a compatible charger, I use this from Amazon:
I have several of these Mroinge LifePo4/Lead acid 2A chargeing and love 'em as they work for nearly any batt:

Cons: They are pricey, but taken in the long haul are a better value for service and overall lifetime.
So for my night-time astronomy habits that extend into the wee hours, this was a great upgrade.
