I have been running with 85ah lesuire battery which when I first used it completed Boo Boo's run with out losing a bar on the C5 battery indicator - recently ,however, it's not been performing too well and it is under a year old. For some strange reason I decided to read the instruction's on my charger an noted the comment 'not suitable as a caravan battery charger' of which this battery is. I was always a fan of slow and gentle charges to look after the battery - however I don't my super safe charger is giving enough amps to fully charge it - found this on the internet :

A new, fully charged battery produces 2.1 volts per cell or 12.6 volts for a 12 volt battery. You must understand what voltage and amperage mean. Voltage is a measure of electrical pressure. Amperage is the amount of current passing through a conductor. As a battery discharges - goes dead - the electrical resistance increases especially with todays maintenance-free batteries. A 6 amp charger probably will not fully charge your battery since the internal resistance of the dead battery is so high. You should slow charge the battery but I recommend a charger with an output of 10-12 amps, see if you can borrow one.

Going to up the amps and see if it helps - ps so much for my ONC in electronic engineering !!!

Let us know how you get on mate, I've always used an Optimate motorcycle battery charger and don't seem to have any problems with that  :-\.
