Replacement of Batteries on an Acorn Stairlift

How to replace the batteries on an Acorn brand stairlift. Models covered are Acorn 120, Acorn 130, and Acorn 130 T700.

Bought Mighty Max brand replacement batteries twice now. They are a perfect fit, last ones were the standard 12v 7ah ones like original. This time I installed 12v 9ah ones. They are exact same size but have an extra plate to deliver more current and run longer if you lose power. I read several reviews first and they work fine, the acorn 130 stair lift charger has zero problems charging them. If you decide to upgrade to 9ah you will need to buy terminal adapters to go from 1/4" F2 Terminal size on 9ah down to 3/16" F1 terminal size on the 7ah. Adapter is F2 female to F1 male. I bought Mighty Max batteries on Amazon, and got the adapters from Battery source. You can get batteries at your local battery store as well as adapters. You pay about $10-20 more for the batteries locally. - Leonard Manchester, Georgia

Will this video work for the ACORN Supreglide 130 T700? When this is installed and you then want to change the batteries, can you get access to the side facing the wall? For example lets say the chair looking up the stairs is on the left side going up and this would then be on the right side going down. Can you get access to the screws on the side of the wall? thanks

This process will work with Acorn 120, 130 and 130 T-700 models. On the 130 T-700 the jumper cable between the batteries looks different, but same process will work. For the screws on the side near wall. Depending on how tight it is to the wall you may need to try these options 1) use a stubby screw driver, 2) use a right angle adapter in a drill, or 3) use a Philips head bit in a pair of vice grips. Ultimately, if it is too tight to access the screws, you may need to remove from the rail to change the batteries.

You might’ve shown the reassembly process and given info on where to buy a replacement battery.

@@mobilitystairlifts4678 Is this the battery that came with the chair or a replacement?

@@mobilitystairlifts4678 is this the OEM battery? Are you finding the life of the batteries the same as the OEM batteries? I want to buy a known good set of batteries.

[@joed5792]

does chair need to be reprogrammed when old batteries are removed and new ones installed?? Or is it simply "plug and play"?

[@mobilitystairlifts4678]

For the straight stairlifts, it is plug and play.

How about the curved ones?

[@mobilitystairlifts4678]

We do not service curved Acorn stairlifts, so I can't be certain.

[@n1kkri]

Can you tell me the OEM brand of the batteries

[@mobilitystairlifts4678]

There is no single answer to this question. I've several brands of batteries from original installations, nothing consistent.

@@mobilitystairlifts4678 Have you had one brand that last longer than another? My experiences with using them with alarm systems has been some last longer than others.
