Title: 12volt battery
Post by: warmshed on 10.08. 2012 16:59
My brother in law needs a new battery on this '59 A10 He wants to upgrade to 12 volts, Ok with the regulator as its convertable.  What battery fits the tray best. Would save a bit of searching if I use one that has been found to fit correctly.  Many thanks. Dave.

The cyclon batteries fit inside the original battery case but what are the A/hrating.  As they are the AGM construction they are a good choice. I was thinking of a stand alone battery that can replace the old case.

Each of my 6v batteries has 5Ah which I believe gives  10Ah  *conf*

Elec trickery is not my forte  *eek*

So to keep my options open, what battery fits nicely on the bike (Battery code please)  without using an empty old black battery box? It just seems to be a cheaper option. Thanks.

Hi I did extensive research into which battery to use for my electric start conversion and I found the best available that will fit into the battery compartment is the USA made Westco SVR15 battery which have now been re-branded as WPC15L
It is a totally sealed maintenance free glass matt design.
They are 14AH and will power your lights for many hours even if your charging fails
You only have to bend over 2 tabs on the battery platform to make it fit
