How do I charge a battery.....?

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

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

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?
