I have a spare 12V 50Ah maintenance free battery. Actually, it's off
my mobiility scooter. One was ok the other went bad so I replaced them both.

How can I charge it..?

I have been told that I can not use a a car battery charger on it.

Any advice most welcomed.

Thanks in advance.

No you can't really.

But you can use an 'intelligent' charger like some of the ones that
Gunsons make. There are also a couple of other ones available but I
can't remember the makers' names now.

Go to http://www.gunsons.co.uk/ and look in the Battery Chargers &
Battery Care section, there are a couple of chargers there which
specifically mention maintenance free batteries. They are universal,
you can use them on car batteries too.

Yoiu can buy a suitable charger at any model shop. These batteries are
extensively used to power electric starters and fuel pumps for model
aircraft, as part of the refuelling/starting equipment.

Many modern car battery chargers are switchable for no maintence types.

Or look for sealed lead acid chargers from maplin www.maplin.co.uk

try lj73q or lo8ab

When I last looked Argos had one.

That's correct, it is a sealed lead acid battery and overcharging
will damage it. Chargers for sealed batteries are generally
expensive if you want short charge times - typically GBP40-GBP150.
If you can tolerate much longer charge times (and depending upon the
amp/hour rating of the battery) there are some chargers around for
about GBP10.

"Maintenance Free" on a car battery isn't the same as a maintenance
free traction battery on a scooter. The charge voltage is different,
and you'll kill it.

You could use a charger for the tiny sealed lead acids in burglar
alarms (and wait a year), you can build / adjust one, or you can buy
one - over-priced that they are.


Talk to the battery maker for the correct voltage specs, and read any
basic DIY electronics book from Maplin on how to build a suitable
circuit. Easiest way is probably to buy a charger from Halfords
(using the case, transformer and rectifiers) and make a new or adjust
the old regulator.

If you look further the Gunsons chargers specifically mention traction
(and similar selaed) batteries I think.

Probably a silly question but can't you use the charging system for the
scooter?

It bugs me that the ad men call what are low maintence liquid electrolytic
types maintenance free just because there are no easily accessible
fillers.

I assume the scooter ones are gel types and require a constant voltage
charge? My Halfords charger says it is suitable for this, but I've not
tried it. It would make sense as aren't many leisure batteries gel types
too?

Swap it for the one on the scooter temporarily and charge it on that?
