Battery size

Hi all

Reading the factsheet about batteries, it states that your leisure battery should not be bigger than your main vehicle battery

On another board someone is recommending a 85AH main and 110 AH leisure battery

I'd go with the bongofury recommendation, but why shouldn't your leisure battery be bigger than your main battery?

Cheers

I think that subsequent experience has proved that there is no need for the LB to have a lower Ah rating than the main battery. There was some talk in a previous discussion of removing that statement from the factsheet.

I have fitted a 110Ah Bosch LB, works fine with my 95Ah main battery.

My Narrowboat had a 500AH L Battery & a 95AH engine battery. Worked fine for the 6 years we lived on it . That "blows" that theory out of the canal.

Phew haydn, my eyesight is not so good these days and I thought you handnt put a 'c' in canal.

Anyway, I quizzedthis sometime back and noone knows where the advice in question came from. All experts agree its not true, so I'd stuff the biggest thing you can find in there. It'll hold a big charge, go for longer and impress your friends.

Oooooh matron!

Just make sure the tray is big (and man) enough to hold it. Supposedly some of the metal trays won't take the larger Numax and Bosch LB's.

I went for a moulded fibreglass one (reinforced with steel), I believe the same as mikeonb4c and corblimey (amongst others)...

Yep, and becuase its supplier recommends the Numax 110Ah, as per the installation in his own Bongo, II played safe and got one of those. V happy with it.
