WTB: Brand new battery for my e30

[bravo 34]

1991 e30 325i. Battery located in the boot. Battery that came out is one of those expensive DIN666's. The battery tray has heaps of room for a larger or different size battery.

Cheers

I can do a Century calcium DIN65 with 3 yr warranty for $250 incl Gst

Thanks Glenn,

will shop around up here and let you know. I'm down your way in a few weeks.

Cheers.

MOF, I got a Din666 from repco for $210 on boxing day when my old batt crapped itself and I was going places without a trickle charger, I didn't have time to shop around (and incidentally had $200 worth of vouchers) I doubt you're gonna get a much better price than Glenn said, they're a pretty big F- off battery.

Also, you might wanna pay attention to where the mounts for a battery are located in the tray if you're gonna swap sizes.

Just be careful that you are buying a Grade 1 battery with a 3yr warranty. Calcium ones are dearer and are better quality than acid filled type. There probably are cheaper ones out there though. Mine normaly retail for $252 +Gst

Thanks guys. As long as the positive lead raches I'm good. I have a longer-than-factory neg lead on their now as I'm borrowing a marine-grade cranking barttery out of the boat (fooking huge!). Held in with industrial cable ties.

I appreciate the advice Glenn. I want to buy a decent battery, but my info is that the DIN 66/65 sized batteries are more expensive due to there being less of a demand for them. So hoping to get something in a more common size that I can make fit.

I suppose if you are not driving the car often a high quality battery is essential, I put a new one in my E30 about six months ago, four of which it has been parked up, want to start it on the weekend and it’s as dead as a door nail, im thinking the tiny constant drain for my back up siren is responsible.

Would a high quality battery like you sell stay charged even when not being used for long periods of time Glenn?

A Din66/65 is the most common battery used in BMW's. Then theres the smaller Din53/55 & the larger Din85

No battery is going to last for ever without using the car. 4 months is too long for any battery that has even small amounts of necessary current draw to maintain clocks, alarms etc

Yeah mine died because I left it over winter.

I have a Projecta KM400R battery charger (it's 2.2A Automatic). I suppose I could just leave this plugged in all the time over winter when the car is mostly parked up?

Cheers.

Never leave a battery charger that doesnt switch off, on the battery for long periods. It will damage or boil the battery dry. There are several types of smart chargers available. I had one on the Ducati & Stabicraft. Both were hard wired and fused.

I've been really happy with the AA batteries i've bought. delivered, installed, tested and cheap if you are a member. They'll take away the old battery too.

They are a sealed battery with 3 year warranty.

Repco batteries are Century batteries rebranded, same warranties etc

Also, ignoring car memory drain from the battery, a battery will also self discharge over time too.

They don't like not being used.

That said - the calcium batteries are a little more tollerent in sitting compared to the standard lead acid type
