These batteries are fully tested and come with the printout of the test results showing capacity and curve charts. They all tested within +/-2% of full capacity. These batteries were used as backup only which is why they are testing like new.

Priced to sell and guaranteed working.

Specs are in the 2nd photo. These are plug and play, ready to use.

Some have a blue sticker on top and some have a black sticker on top. Both are the same model number and battery.
