Hi Guys, any ideas where I may be able to get a replacement battery like this one at all?? I need it for a childrens motorbike - I purchased the bike second hand but I am afraid the battery has had it!!

Thanks as always,

It's a sealed lead acid 6.0v battery. A battery centre would have something similar. Replacement would need to be 6.0 volt, and have a capacity of 4AH or higher.

Something like this from budgetbatteries.co.uk should make a suitable replacement provided the dimensions fit the battery holder.

Or a place that does electric wheel chairs should do stuff like that, and a lot of towns have one of them in them!

Hi guys - ok so I think the internal charger has broken within the bike as the battery is not charging - I have the original from it and also a new replacement I purchased after your help on here!

The question is - what charger can I purchase to see if its the charger? I cannot see what to purchase? Just a cheapo will be fine and overnight is fine - I just cant't seem to find what I need!

Thanks :-)

Hi Malakite
Argos do a cheap car battery charger that switches between 6volts for bikes and 12volts for cars, might be worth checking out?. Or any motor parts place should sell something suitable.

Something like this might work?.
But you have to make sure the switch is on 6volt.http://www.ebay.co.u...=item1e6c88beafYou are in the U.k?

Hi there - yes I am! I do have a Graupner Ultramat 14 charger but I don't think it works with this type of battery!

Also I wonder if I make some crocodile clips instead of the standard Tamiya 7.2v battery connector that comes from it to charge my car batteries, if this will work as a charging unit - does anyone know??

The Graupner Ultramat 14 charger unit will charge lead acid batteries (Pb). Be sure to set it up correctly for the 6.0v Pb battery before connecting the charger to the battery. Refer to the manual for programming. The charge specifications should be printed on the battery or with the documentation that came with the battery. It is best to disconnect at least one of the terminals from the car when charging.

Making up a set of leads with alligator clips is no problem. Be cautious to never get the output polarity incorrect when connecting the battery or short the two output clips though as it's easy to get it wrong. A short or reverse polarity will damage the charger.

The Tamiya type molex plug is rated at 7.5Amp and the charger output is 5Amp, so the connector is well within the capability of the charger.

Hi Mark - well I charged on usual settings but lowered the ampage slightly and it appears to have charged the battery? I could not find out exactly what charge rate I needed so went for 1.0 amp (I usually have it 2.6Amps on a ni-cad 7.2v??
