Group: Forum Member Posts: 113, Visits: 351	Ive installed a leisure battery in my G4 with a link charger from the main battery via a switch. The leisure battery came fully charged and linked to a 1000w plug socket which worked fine about 3 mths ago - ie 700w drills. Tried it today and it cuts out, even with a 100w light bulb. Am I right in thinking the battery may be discharged? and if so how do I test it to confirm its discharged (apart from plugging in things if there is a way) ? I dont understand why the link charger has not topped up the leisure battery. Any views. I do mainly short journeys but the link should charge up the leisure battery ( as it does the main started battery) the link stops the main battery discharging but allows both to charge). Im using a thinner wire from the switch to the leisure battery - perhaps this should be the full heavy duty battery wire - although the instructions indicated it would be ok. any views... www.thelettingagents.co.uk

I thinbk its the short journeys I do and the fact the leisure batter has been sitting for 4 mths over winter with a low use on it. I think the journeys I do is fine for the main battery but not enough left over for the leisure one as well. Im off to Scotland next month for a tour in the G4 so will give it a good run out. In anyevent a full battery will be enough for what I need - rechargers for phone/satnav/small microwave/toaster/heated blanket. www.thelettingagents.co.uk

Apparently the chargers that the AA/RAC have might be able to kick a battery like that back into life, but it may be easier to get it replaced under warranty. How have you got the charging circuit wired up? A piccy or a diagram would help. Cheers, Mark S.

Followed the diagram & Instructions right Im 95% sure. If it hasnt charged by tonight 5pm - 72 hrs then I will take the bat back to halfords. www.thelettingagents.co.uk

E Group: G4 Member Posts: 589, Visits: 3.6K	Hmmm, not sure that would work correctly TBH. The main battery will probably take all the charge with the second one getting virtually nothing. Think you need to add in a split-charge unit, something like this If you have a "normal" battery charger it won't kick the battery into life, you need to give it a kick with a professional charger to make it work. Easiest is to take it back under warranty and get it replaced. Cheers, Mark S.

Thanks for the info. - The switch is very similar although it wont allow a drain on the main battery just a one way charging to the leisure battery. Trying to find the link but it is designed just for this application type. I presume the problem is/was that im driving long enough to top the main and the spare battery, just the main battery. Perhaps this thinking is wrong. With a staight split, Im worried that I may flattern the main battery if half or part of the charge is being split and there is not enough for both? www.thelettingagents.co.uk
