OLLIE 26 Report post Posted July 2, 2007 So it's time for me to get a new battery for the E30, these M20's need a fair bit of battery juice to get going and my battery is so exhausted it won't even start the car even after a good charge. (fingers crossed it is just the battery) it would be good to hear what people recommend, what experiences people have had etc .... I need a standard battery for my daily and a compact battery for the race car (roll cage is in the way), from past experience 450 CCA or thereabouts seems to be the go ....

hotwire 352 Report post Posted July 2, 2007 Din 55 is the correct fitment battery for these cars. They are rated around the 450 -500 CCA depending on brand. Being a Euro spec battery they are more expensive than the common fitment types but they fit & secure as original. Standard type can be used but dont always have the ledge around the bottom of the case for the retaining bracket - a must for WOF purposes. Quote Share this post Link to post Share on other sites
cainchapman 0 Report post Posted July 2, 2007 Best batteries on the market for cars. http://www.enersysreservepower.com/ody_b.asp?brandID=5 Check under the seat of a Formula Ford if you want a recommendation. In another form, used in Harrier Jump jets etc. I used to sell them. Quote Share this post Link to post Share on other sites
bravo 35 Report post Posted July 2, 2007 The car audio crew recommend Optima. (See nzice forums) Quote Share this post Link to post Share on other sites
cainchapman 0 Report post Posted July 2, 2007 Optima are not great. Better than your average Flooded cell, but the power density and charge acceptance are nowhere near as good as the Odyssey. There is a significant difference in running a bit of electronics and cranking a car with the best power to weight ration. Quote Share this post Link to post Share on other sites

ED1RTY 2 Report post Posted July 3, 2007 Dont go hella. They are crap. I have pwned 4 of them in the last year. All of them have had the plates collapse/erode I got them all replaced under warranty and had the car looked at and nothing was wrong. Optima FTW Quote Share this post Link to post Share on other sites

OLLIE 26 Report post Posted July 3, 2007 problem solved AA came to my house and replaced my battery for the same price it would have cost to get a century battery (one of the better brands) not delivered, they tested it etc .... great service. the batteries the AA use are their own, they are sealed calcium batteries made in japan. I am happy with the final result $159 later. except for the diagnosed MYSTERY BATTERY DRAINAGE Quote Share this post Link to post Share on other sites
