I'm looking at a D31A for my D3 - always had good luck with yellow tops. Anyone have any other recommendations?

Replacement battery for a D4

(Vested interest flag ... I sell batteries!) ...

Optima D34 will happily operate as a starting battery. The CCA rating is conservative, and we have found that the battery technology delivers the CCA for longer each start, so a smaller capacity battery will often out perform conventional batteries. Eg Cat D6 Dozer 24v, uses 2x N150 batteries (@1000CCA) (one each side of the driver), 2xOptima D34 (@750CCA) (mounted in 1 box, freeing other for tools) have been starting/running dozer for 6 years now.
I recommend users who have D34 as secondary battery, and panic when out the back of beyond etc their starting battery fails (usually the original Varta in their D3 or D4) , to rewire the isolator to use the D34 as starter ... they have always got home, and sometimes taken few months to replace the original starter.

Thanks - I've been following that thread. Was hoping to see someone going for a yellow top.
I've got a good battery specialist that I pass on the way to work, and he sells Optima, so I might drop in and see him.

Supercharge GOLD PLUS MF88H, cars

This is the one that was in mine when i bought it and it seems to be going ok.

Have spent the last two days washing the car inside out though with radio on and its now dead.... Hopefully reviveable. Forgot the dash will go spastic when battery is dead... Was thinking wth is going on here...

Would swap it out for a Optima tomorrow though if possible...

When you say rewire Michael, does this just mean connect the two positive leads together and disconnect the isolator (SC80 in my case)?

I've been meaning to make up a positive lead for that purpose for ages.
