Great battery!

The battery arrived mostly charged. It took 13 minutes to get it to full charge after dressing it for the first time. It also arrives with a convenient sticker for keeping track of the date it was first use.

MK 12V SLA Battery

I bought a set of 2 for our FIRST Robotics team. I've been charging and checking their capacity with a battery beak. One of the batteries is fine. > 120% capacity. The other one is worse than some batteries that we bought and have been using since 2019. It started out at 91% capacity after a full charge. I've had to do multiple overcharges to get it up to 100% capacity.

Electric Purchase!

The batteries arrived in great condition and AndyMark was great in communication and ensuring a speedy delievery.

We try other batteries, but always go back to these

There are many batteries out there, and we have tried a variety of them. The only one we have found that is consistently reliable in delivering expected capacity, lasting for a season's worth of cycles, and degrading in a predictable manner is these MK's. To minimize battery issues during the season, we try to always buy new batteries each season, move last year's batteries to the 'practice' status, and retire the ones that show significant degradation in capacity. We have built a 10-amp load tester, and test for capacity under 10 Amp constant load. This is our 'go-to' battery - Team 1425, Wilsonville Robotics ..... Error Code Xero
