I am confused by various statements as to when the leisure battery is fully charged.
An article in the CC Magazine says a battery is fully charged when the 'rested' battery is at 12.7 to 12.8v.
My standalone intelligent battery charger has settings at 14.7v for normal batteries, and 14.4v for Gel batteries so as not to 'cook' them.
I have heard that in-van chargers are only 13.8v as they can be charging for a long period, but at this voltage the battery will only be charged to about 80% capacity.
As the charge state of the battery is defined by voltage (see below) then surely any charger that has an output of at least 1v more than a fully charged battery will do the job, but the bigger the difference the quicker the charge?
12.7v 100% charge state
12.5v 75%
12.4v 50%
12.2v 25%
12v or under - discharged.
