Mighty Max Battery 12V 35AH Gel Replacement Battery for Invacare Pronto M51 M61-2 Pack

Great battery so far. Price is decent and is holding a charge well.

We were having trouble with power chair and getting the indication that the controller was bad. We ordered one (used) and got nothing so tried again - nothing. After watching a video online about repair them we learned that certain make would send the wrong trouble light if there was a problem with batteries. After getting the right tool to check the batteries (they indicated full 24 volts on voltage tester) we found one had a bad cell. After purchasing these (gel was highly recommended for more recharges) the problem is solved.Batteries came swiftly and were ready to go.

The best thing I could of bought

These have increased Amp Hours over the original batteries. It is an upgrade. Very nice!!

The batteries worked about a month and quit.

I purchased these batteries for my 19 yr old power chair, that weight 200lb and I always have enough power. I don't know how far I've gone on a charge but I can say that after a week of tooling around the house, my charger said they were still at 80% of charge. I couldn't be happier.PS. I normally don't go a week without topping of my batteries; that was to test them. I usually top them off at night, every night.

I used these in a Power wheelchair that somebody gave me. It's old and slow but doesn't have any battery issues with these installed.Good buy! Shipped quickly.

Fast delivery good quality
