Andrew Posted September 3, 2021 Report Share Posted September 3, 2021 Hi everyone, I've read a few topics about batteries, I'm planning to install a leisure battery under the passenger seat and presume somebody has done it before. If so please let me know the size / dimensions of the battery installed. I'm looking at 'low box' versions but wondering if normal sized leisure battery would fit under the seat. Many thanks Quote Link to comment Share on other sites More sharing options...
Pritch Posted September 4, 2021 Report Share Posted September 4, 2021 Hi there, if it helps, mine is under the drivers side, as think a battery will interfere with turning the passenger seat. My battery is what I would call 'normal size'. HTH Quote Link to comment Share on other sites More sharing options...

Cheers. Have you checked there are no obstructions under the passenger seat. I assume you have. I ask because.. Some Alphards have a frame / chassis assembly under the passenger seat for additional amplifiers and 'stuff'. 1 Quote Link to comment Share on other sites More sharing options...
Chris.ac Posted October 15, 2021 Report Share Posted October 15, 2021 I think both my front seats have a bunch of factory fitted amps to power the 18speaker sound system I too would like some aux battery, as I travel for work and need to occasionally use laptop etc. The engine bay is a lot more packed than my older Regius, which had the possibility to fit two regular sized batteries. Im thinking some custom made Li-Ion battery pack I can install behind one of the side panels in the rear, or in the 1st aid kit cubby at the back may be the best for my needs. 1 Quote Link to comment Share on other sites More sharing options...

Chris.ac that's an interesting idea, I've used a few small rechargable ones for RC cars so some of those linked together might be good and they're small so like you said they can go behind a panel. I'm just wanting to power the TV and plug socket / USB in the back and perhaps mini fridge on journeys away Quote Link to comment Share on other sites More sharing options...
Jezmond Posted March 21 Report Share Posted March 21 I just got my Alphard and had a leisure battery fitted by a place called Fantastic Campervans. They fitted the leisure battery under the bonnet next to the main car battery. Apparently this is possible with the 2.4 litre engine but not the 3 litre due to space. It's well worth looking into. In not sure what the size of the battery is but they said its enough to power a fridge for a day and a half Quote Link to comment Share on other sites More sharing options...
