Car battery advice please
« on: June 14, 2019, 22:57:34 »
The battery in my 2015 Honda Jazz  ( yeah I know) has died. I have put it on trickle charge and got it from 7.6 volts up to 13.7 volts but I doubt it will last. The car was OK when I parked it up and the next morning all the electrickery had drained away. How do I tell if it is a battery fault or something wrong with the charging system. Also the battery is 35 amp hour 290 A , do I have to buy the exact same. It is a Varta and they do a 35 amp 400 A version will that be OK?
Look at the clock and the calendar.
It'll never be now again.
So just get out and do it.
As fast as you possibly can.

Dave, you need to attach some load to the battery and see if the volts vanish before your eyes. That will tell you that a cell has died.

The important things to look for in a replacement are that they're the same size, the terminal polarity matches and the amp rating is at least equal. A few more cranking amps available won't go wrong.
Seems pearl asbo orange is faster after all....

Update:- After 14 hours on trickle charge I installed the battery and so far it is behaving normally. I still don't know what caused it to go flat.  :shrug: But having just shelled out £135  for a new front suspension top housing on the Doblo I was not looking forward to getting my wallet out again.
