How do I "maintain" my power wheelchair batteries?

Simple answer is to charge them overnight with the charger the manufacturer supplied. Do this every 2 weeks even if you never turned on your wheelchair.

Don't forget, or decide to leave it longer - even once - as your batteries WILL be damaged or deteriorate. Batteries self discharge over time even if unused. And the batteries in your mobility device do NOT like sitting unless fully charged.

You do not need to read any further!

Less simple answer...

The above advice is very generalised. Not all chargers or batteries are the same. In an ideal world you would need a maintenance charger that holds your batteries at the perfect voltage for long term storage.

Some mobility chargers do just this! But they don't tell you that they are doing so. So only a voltmeter and some skill will let you really know. Some just charge until "done" and stop completely. Again only a Volt meter can tell you what is actually happening.

The correct storage voltage (Float voltage) the case of a typical Gel battery would be approx 13.5 Volts per battery (so 27.00v for a typical powerchair).

Or in the case of an AGM battery which are becoming more popular in mobility devices then 13.25v (26.5v) is best for long term storage. 

Suitable low power maintenance chargers are available from various places. If you value your batteries these are a better bet than charging it every coupe of weeks with your mobility charger and will make your expensive batteries last longer in storage.

Also remember that even when turned "off" your powerchair or scooter will be taking "some" small amount of power from the batteries as that computer under the seat is still live. The extra drain on the battery means that the batteries will discharge faster if they are left connected.

So if you are going on holiday or leaving the chair for more than a couple of weeks, then its best to fully charge overnight as usual and then disconnect the batteries completely from the powerchair or scooter.  Don't forget to re connect and charge them as soon as you return!

Having said all of this batteries deteriorate in other ways too. One way is internal corrosion that happens over time. This happens anyway even if the batteries are kept charged up. So long term storage is better in a cool place rather than a warm house. This slows deterioration.

In an ideal world you would fully charge them, store them disconnected from your wheelchair or scooter in the fridge and use a dedicated float or maintenance charger 24 hours a day. Although this is a bit impractical...

So just keep them charged!

 

My powerchair has a special arrangement, allowing me to use a cheap 12v battery maintainer. As seen here it holds the batteries forever at the best possible voltage for the longest service life.

I have a 12v / 24v battery connection system, as seen here.  You don't need to know how this works! You just need a 24v battery maintainer, and use the chairs usual charge connection.
