Dawid08 Posted January 6, 2020 Posted January 6, 2020 hello, i know nothing about charging battery that's why question is can i charge my battery with charger i got? on the picture u can see them both thank you for your help. https://ibb.co/hfkwLrh https://ibb.co/dfw3mkR Quote
Stu Posted January 6, 2020 Posted January 6, 2020 Hi and welcome to the forum It says on the battery quick charge 3A x 1H which means at 3 Amps it will take an hour I reckon this may well be the max it could take and with your charger being 4 Amp I wouldn't risk it! Unless its a smart charger and designed for bikes then that way they know how much charge to put in and at what rate Quote
Dawid08 Posted January 6, 2020 Author Posted January 6, 2020 probably that's why i heard from first second something like battery starting boil. Quote
Stu Posted January 6, 2020 Posted January 6, 2020 They do fizz a little while charging but if its boiling then it may be shagged! has it been left flat? Quote
Dawid08 Posted January 6, 2020 Author Posted January 6, 2020 yeah ofc , i have to add yet that battery have 4 month Quote
Mississippi Bullfrog Posted January 6, 2020 Posted January 6, 2020 yeah ofc , i have to add yet that battery have 4 month Eh? That makes no sense to me.If the battery is very flat, anything under 12volts, then it won't take charge off a conventional charger. You need to prime it at something under 500Ma. A cheap plug in gel cell charger will do that no problem. You need to raise the voltage back to 12 volts before it will take a charge.But as Stu says, you really want a charger specifically for bike batteries, usually with an output less than 1 amp. If you don't ride regularly get a maintenance charger that can be left connected. A CTEK 0.8 for example. Quote
