Another battery question

[mick]

I recently connected my small CTEK charger to one of my 2-year-old service batteries as the battery was down to 12.5v. After 5 minutes or so the charger green light was indicating charged. Is it normal for such charging to take so little time?

That does seem quite quick.

What Ah is the battery?

Ignore it and charge overnight.

No, give it a full 12 - 24 hour charge.

Thanks. I will heed the advice. Battery is 86aH.

A fully charged battery should, at rest, be about 12.8v. So, as others have said, charge overnight. Then leave for 24hrs with no load on it (best disconnected) and then stick a voltmeter across the terminals and see what you get.

What mode did you select on the charger?

Could be a case of RTFM.

I am a recent convert to RTFM and life has become much easier!
