I have topped up my leisure batteries today and i am charging them using the on board charger.
How long can i leave this charger on?

Charging systems in modern motorhomes are 'intelligent' systems. They use a multi-stage charging regime that ends with a float-charge maintenance cycle. Once the batteries are charged it will shut down and 'slumber', just keeping things topped up. You should be able to leave the system plugged in without any problems. Many funsters leave their vans plugged in all the time at home.

Even if your motorhome is not modern it will normally have a 'float' charger. With these the charging rate will steadily decrease as the battery voltage rises so in a fully charged battery there will be no charge. Even these you can leave on all the time.:thumb:

I leave mine on charge as often as I can for as long as I can.. It's good for the batteries:thumb:
