Mighty Max Battery 12V 3AH SLA Replacement Battery for MK ES3-12 - 2 Pack Brand Product

Exact fit

We needed batteries for our stair chair that hasn't worked since 2016 when my mom passed away.. We didn't use after that, now I need it and company wanted 1,000.00 to come and put new battery in.. We checked Amazon and my husband said he could put it in... Works like a charm I use it everyday now.. We got it very quickly from Amazon and he installed it same day.. It always pays to check Amazon..

Needed to replace batteries in a relatives lift chair.Good price and seem to be good quality product.

The batteries are probably fine. The problem is it turned out to be a defective computer back up so I really don't have a use for the batteries. I had disposed of the box, etc. by the time I figured out it was the device and not the battery.

These batteries fit our stairlift, unlike the ones we had ordered from an online battery company that were supposed to fit. We're very happy with these replacement batteries.

These batteries came very quickly and was the perfect fit now my dad can use his chair again

These batteries never charged. I installed them in stair lift and they were dead and wouldn't hold a charge. Had to leave and didn't get them removed until it was too late to send them back. I heard one of the biggest scams was dead or fake Chinese made batteries. I may have been scammed here.

Perfect replacement.worked with no problems
