The battery required for my 1950 Commer is 12v 63 amp hour. I have phoned round and these are quite expensive compared to 12v 90 amp hour commercial batteries.
Is there any reason not to use a 90 amp hour battery? |

You can use any size battery you can accomodate as long as it is the same voltage, though going smaller is not a good idea normally. Too small and the starter motor load may be too much for it.
Obviously a larger battery will hold more power, but if your system takes too long to charge it you may have less voltage available after a longish discharge and hence slightly dimmer lights possibly while the voltage is building up again.
Jim.
P.S. I have been running my 2 litre "special" on batteries intended for a 1300cc car for 30 years and a six figure mileage. Simply because there is not room under the Bonnet for a bigger one. Of course I have had several, but none have ever failed or been damaged timewise. In fact my current one was fitted in 2009. And is causing me no problems, though I am aware that its capacity is now falling. Hardly surprising though?
Still good enough for day to day though.

When I needed a battery for the Singer I measured the maximum size the battery tray could accommodate and then went to the local friendly factors and bought the best/biggest/most reasonable battery I could.
Went for a Varta.
Also, as it looked a bit too modern, I gave it that retro look..Not great from a warrety point of view but as long as I get a couple of years I will be happy.

Thanks Dave, saves a fortune over a proper lucas make and probably a bit more reliable?
