Battery change at an Handicare Minivator Simplicity 950
-
-
Hello, I own a Handicare 950 who is since few days operating in upward direction in half speed mode. Downwards and under no load the behaviour and speed is as normal.
I suspect that the battery reached end of lifetime and I have to replace them.
If somebody can give me an dismantling instruction how to do, so that I do not need to remove unnecessary parts and covers, would be great.
If I can get the battery type/size and dimensions in advance, it would save me time by ordering the spares before starting the work.
Thank you for any help in advance.

2 12v 7ah battery’s £20 each from Screwfix
will need good access to the carriage so run it the stairs a bit so you can see under the downside carriage cover, this is the one you need to remove, three fixing, two you can see on the top of the cover, at the hinge, Phillips headed screws, the other is either an allen key headed bolt or Phillips headed screw in a recess in the lower downside lhd corner of the cover, remove this one first then holding onto the cover remove the other two fixings
slide the cover down the rail till you can see inside it, there will be two cables on circuit boards stuck to the inside on the cover, slip these off the plugs noting which cable goes where? then unplug the two red cables off the switch and slide the cover down the rail and out the way
you will see a red and black plug, the battery lead plug, separate the two halves
the big silver box hanging underneath the carriage is the battery tray, held in place from underneath by another allen key bolt or phillips headed bolt, loosen it till the tray starts to move, then slide it out from under the carriage, it slides out, pull it out being careful not to pull any leads off the main board
the battery tray has to be separated to get the battery’s out, note the cable routing and the location of the battery terminals as you need to put it all back to gether the same in order to get it all back in place and connected up
undo the bolt, separate the battery tray, remove and replace the battery’s, rebuild the tray
now is a good time to take a look up under inside the carriage, clean out the fluff off the rollers, check under the motor gearbox for signs of an oil leak, clean and lube the center guide roller
ok all good so time to stick it all back together 🙂
when you pulled the cover off you probably saw a spare lead floating around, normally a blue or red sleeved one, it’s surplus to requirements so unplug it off the board and bin it
gently lift the cables out the way and slide the battery tray back into place, tighten the bolt, does not have to be really tight! plug the battery plug back together slide up the cover, replace the leads onto the plugs on the boards, switch on the lift, the diagnostic display should fire up? which means you have the correct leads plugged onto the correct boards, grab a remote and test they still work then replace the top two screws, then the bottom bolt, can be a pig to line up, again this bolt doesnt need to be overtightened!
once its all back together and running, check the operation of all the safety edges and if all ok? charge yourself £200 that’s for the call out and the battery’s mate, and that’s doing you a favour, you wont get anyone else out here at this time on a weekend 😉 -
fredt, thank you for the quick answer and the very detailed instruction. I supposed that the battery change at this type is not that easy as for other units, but you gave me a help to fix it, hoppefully.
If I would have a service nearby who would work on second hand purchased stairlifts, I would let them work on it. Unfortunately these kind of service shop will denied to work on these units, they like to sell new units together with service contract.
So I will try my best and will keep you updated if I was succesfull. THANKS -
Look up Ur local Handicare dealers, they would be happy to change ur batteries and service ur stairlift….

It’s done and it was much more easier than I thought, be a little careful with the wiring than it works. After checking all safety functions the lift was working as on the first day. The Idea to contact the local dealer is great, unfortunately it is not working because the guys do not like to service stairlift which bought second hand and not directly from them and blocked any requests. The required batteries type NP7-12FR-12V-7.0 Ah with the dimensions L151 x B65 x 97,5 mm are easy to get locally.
