I bought my parents a used electric wheelchair and despite the seller saying a number of times that the batteries were excellent, they are bad. Leaking acid and not holding a charge. I had them tested at CanTin and they both came up with a fail replace.

So the batteries are full sized deep cycle car batteries (2) and they are 12v gel.

Anyone know about these batteries and the best place to get them?

Thanks

For a good deal on them track down an employee of a health service company. My brother works for Lawtons or one of those companies. He brings home used decent ones all the time.

I'd try Napa, carquest etc 1st. I'd think mobility outfits would charge a premium

We have a "battery guy" here that stocks just about every kind of battery imaginable. I picked up a couple for my UPS the other day and the prices were good. Try a search for battery outlet or similar in your area.

Thanks for the replies. I am learning about batteries today. There are 2 main types of deep cycle batteries. AGM and Gel. The AGM has glass fiber either between the plates or the plates are made out of glass fiber. The gel battery has gel instead of liquid. My batteries are gel. The gel is better in the cold, and apparently won't spill if the battery is cracked. The AGM fiberglas will keep the liquid from spilling because the glass mat acts like a sponge.

There is also a system for sizing. The batteries I have are group 24. So I have to make sure the batteries I look at are Group 24 to fit the chair.

Then there are power ratings. Mine have 335 CCA and 74 A. H. @ 20hrs.

I will be looking into different options, hopefully I can get something for under $400-$500 for the pair.

Thanks. I agree it is a bit pricey especially since I need two.

the two above posts give you an idea of the two main types of deep cycle batteries. Note the cranking amp rating on them both. You can either have a good cranking battery or a long lasting battery - not both at the same time. Look for no cranking amp rating or a low cranking amp rating for your wheelchair battery needs.

DEEP CYCLE BATTERY

The regular deep cycle units are not as good because the plates don't like all the banging around the batteries are subjected to. At least that's what I read...

The batteries in it list 335 CCA. Then it says 72 something @ 20 hr. (going from my bad memory. I will edit post when I check the battery.)

a little banging never hurt anybody. It's more vibration that kills a battery. The lead breaks loose and falls off the plates, collects in the bottom of the battery until it shorts everything out.
In your price range, you are stuck with the lead/acid technology. Some makes are sealed, some are not. Watch the cranking amp (CCA or CA) rating, lower is better for your application. You need a slow trickle, not a huge rush of current.

This Costco battery says it does both well......but I find that hard to swallow.

Thanks. That battery is the best alternative so far.

I am curious how do you know so much about batteries? I appreciate your help.

I called the manufacturer and they say the gel batteries are the best for constant drain and charge. The replacement gel battery from a dealer is $375 x 2 batteries. I think for the amount of use my parents will want the Costco battery is a good alternative. I am wondering if I can buy something similar but pick it up and save some money. The Costco is only available online, and the price includes shipping. These batteries weigh at least 50 pounds and would have to be shipped as hazardous.

No batteries offered on Amazon Prime either.
