uprated alternator

[probey28]

hi all. I have a 2.0l Aircooled t25 on an x plate. just wondering is it possible too get an uprated version of my alternator or could i have my alternator uprated. i want too run a couple of leisure batterys. if so could someone please point me in the right direction

Not required - two 110Ah leisures will be charged by the standard alternator.
Think of it this way, do you use a 100A battery charger for off vehicle charging normally? Do you even use a 45A one? I use a 20A battery charger for charging two 110Ah leisures together off the vehicle.

I have a 45 A alt and two leisures and no bother here.

if your battery isn't charging you need a leisure battery charger which is different to a normal one
The Alt would not charge it 100%.


they only last 5 years as well.

good grief
well if you want that sort of thin there it is, and I'm sure it works just fine.
take a look in the wiki though...
there's a very simple and effective diagram in there of a split charge system.
A 70 amp relay should be enough
you can even get one that'll do the fridge too
maplins sell the relays and so do most motor accessory shops

I bought one for £3.
