Flat Battery .....

Hello, As you know we are newbies and for some inconceivable reason left our fridge on 12 volt while our caravan was in storage. Result being flat battery - even we cannot work out while we left it on! We don't have a mains supply at the storage place to recharge it so need to disconnect the battery to bring it home to charge. To do this we were thinking of purchasing the following charger:

Is this one any good or suitable as the reviews look good. Until we get the batter charged our holiday is in storage city as we rely on the motor mover to take it in and out! Thank you very much for your help and advice :-)
