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.
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.

"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.

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

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
