Works as promised. Used a pair of the 10ah to build a power box out of a Pelican 1200 case for kayak fish finder and for remote work arrangements.

I already own a few of these 12v 10Ah, buying more since my desire to add them to more of my electronics. These BATTs are very lightweight when compared to lead acid. the recharge ability is also simple especially if you use their charger.
buying these two at a time since its a better deal and I already know they are great

I used 4 of these in a series parallel configuration in an old APC Smart UPS 1400RM. I was able to run the system for over an hour during testing. I’ll be curious to see what will happen if I get a much longer power outage.

I was also able to adjust the UPS battery voltage to 28 volts with a little bit of programming.
