CG Batteries and ignition things

[Mikey7094]

Hi

My bike needs a new battery thanks to lack of use. It's a 6V CG125, with a lead acid battery. I've only every dealt with sealed car batteries, so I don't really understand how the wet lead acid batteries work. Can I just put new acid in it, or do I need to replace the whole battery?

I'm also quite confused that Wemoto have two types of battery for my CG, one a brandless pattern one for £13, and the other a Yuasa one for £10. Why is the branded one cheaper?! Are the Yuasa ones any good? Are they sealed instead of wet?

Next question, and this is probably a long shot - has anyone recently bought an ignition coil for a 6V CG who can vouch for its quality?

I ask because I bought one from David Silver that didn't work - bike kept cutting out and was down on power. They refunded me, but now I need another ignition coil and don't want another duff one. The one currently on my bike doesn't actually fit - looks like it might be from a C90 or something.

Any help appreciated - I'm not that smart when it comes to electrics.

Cheers

Hi there top up the battery cells with dionised water (rain water) charge and retest if still working properly it's gone. Replace it

Well, it is completely gone - the bike runs of course, but the battery only charges enough for maybe two indicator flashes! (NB no problem with charging system, before anyone asks.) I just wondered if replacing the acid was enough.

Mikey,

did you ask Silver's to send a replacement coil? Might have been one duff one in a batch - maybe worth a try?

Re. battery: no idea why a Yuasa would be cheaper; maybe a bulk buy they can discount heavily? Given the choice, I'd take the Yuasa every time (seem to think they were standard fitment on early CG's). As for your current battery, once they start playing up, it's often the plates inside that are banjaxed. Topping up with fresh acid won't help as the plates tend to have shorted-out internally.

Hope you get her sorted,

Rick

Just top up the cells with dionised water it's available in supermarkets and auto stores

top up with dionised water then charge the battery when charged check the levels and top up if needed if not test the battery with a multimeater and it should be around 6.5 volts every 30mins it may drop to 6.3 volts but should stay around there just keep testing with the multimeater every hour around 3 times if it keeps droping blow 6 volts it gone and you need to get a new one .

also test the rectifier if this has gone this could of damaged your battery and can damage your new one

as for your ignition coil i have one from ebay and its been ok up to now


hope this helps james

Thanks all - I think £10 for a Yuasa battery is probably worth it, then. And I'll chance an ignition coil from eBay.

(I think my coil was from a duff batch - I notice David Silver don't stock them any more!)

Cheers
