Recently had the caravan serviced and were told that the battery needs replacing, it's only 2 years old. We use the caravan a lot, and the mover. Any advice? And what one to buy?
is it playing up? if not why change it yet? remember the dealers/service guys are after a quick sale on items too you know, if your unsure why not just carry a full charged spare one with you
The best solution is to buy a voltmeter and do your own checks as that way you will know from your own findings if the battery is defective or not. Take the battery off the caravan, connect up to a smart charger at home and fully charge the battery. Disconnect the charger and then check the voltage daily with the voltmeter to see if the battery is holding a charge or not. The initial reading should be around 13.8 volts so jot down on a piece of paper, day 1, day 2 etc. with the corresponding volts and see if the battery has maintained the voltage after one week. If the battery has lost voltage to around 12.5 volts then you know that a new battery is required. Remember that a leisure battery needs a lot of TLC so the age of the battery is irrelevant providing it hasn't been neglected. I have a Lucas 100ah. leisure battery which is now on it's 5th year and still in good working order.
Thanks, we keep the caravan at home, with electricity connected all the time.
Finding more info, it appears that there are 3 makes of battery that are verified by the NCC, Banner being one. But are there any which give a guarantee other than manufacturer defect?
yes mrs bonce, but that doesn't answer the question of is your battery actually not doing its job for you? if your on rhu 90% of the time and the only time you are fully running off your battery is to use the motor mover and your current battery is doing that job no problems then why change something that doesn't need changing? basically the service person has only scared you into thinking something needs replacing when it clearly doesn't
The onboard charger serves it's purpose on a temporary basis because it only charges to a maximum of 80% of the battery's capacity therefore shortens the life of the battery. The advice is to remove the battery and connect to a smart charger once in a while as it charges to a higher capacity then remains on a float charge to avoid over gassing which is overheating leading to buckling of the internal plates. When I said that a battery needs a bit of TLC that's exactly what I mean because people think they can just connect the battery up and forget about it. There's plenty of information on the net you can read about so don't just take my word for it, check it out for yourself.

Yikes, now I'm confused. I was under the impression that my 'vans charging system is effectively a "Smart" charger. Have I got that wrong? Would appreciate any advice.

No, the caravan's onboard charger is not considered as a smart charger and like I said, check it out for yourself as the link below confirms what I said but in much more detail. Hope this helps.
