Meant to be reasonable day tomorrow, so thought I would take the big bike! Alas a flat battery has put a stop to that. My Aldi charger won't even try to start to charge it as its so low, 1.5 volts. It has sat for about 3 months and is possibly the original battery.Can I jump start the bike from the car or is there too many amps for the bike system?The alternative I guess is too bump start it, but Im not to sure how to do that, can someone give me a step by step guide? CheersNick
I love this site, thank you.Little bike is a ybr125, not sure if its 12v or 6v but that's a good idea Millietant.
Fazerider is spot on regards the CTEK charger.I've had one permanently connected to missus' Foxeye 600 for the last 6 years and it has never let us down.That includes the bike having an alarm fitted and the bike not moving for several weeks at a time.Fantastic bit of kit.
A friend told me the other day that the shops won't let you fill the battery yourself with the acid pack at home any more. He said they have to fill and seal it prior to purchase now. Can anyone confirm this?.
Most modern battery chargers wont recognise a battery if it drops below a certain voltage. I think mine fails if the voltage drops to below 9 volts. I can revive them somewhat, with a voltage regulator/convertor Ive had for years, input is 240v ac and I can have varying outputs 0-12v dc, then put the charger on
I've jump started bikes from the car many times without any problems.
QuoteI've jump started bikes from the car many times without any problems. If anyone is thinking of jump starting a fuel injected bike from a car *DO NOT* have the car engine running, otherwise you could fry the bike's electrics!I have an Optimate charger which claims to be able to recover deep-discharged batteries, although I've never tried it. Note, however, that if one (or more) of the cells has died, it will still register as fully charged, but you'll have less power to crank the engine. I found this out when a brand new battery failed very soon after fitting it. The only way to check properly is to find a friendly local garage and get them to put a drop-tester on it.
Sorry Fazersharp, obviously I'm not sharp enough to remember whose post I am replying to Mine is the CTEK one, which I bought off the internet.It's the XS 0.8 bike specific one and it did a great job of recovering the battery after it had gone completely flat, which is why I bought it.
