francoisv 466 Report post Posted July 2, 2014 Fellow Sporters, im in need of some advise around a replacement battery for an E39. My Ex-Touring had the standard massive brick, but I have relocated the battery to another part of the car and was hoping run something slightly smaller. No I have less then half the electronics running now, after having removed all the Audio and Nav gear along with interior lights. Any suggestions on what kind of battery I could use?

allan 295 Report post Posted July 2, 2014 (edited) Cannot offer any advice on other battery types you could try. Even having removed the audio and nav gear the e39's have a lot of other electronics going on in the back ground requiring juice so a good battery with some amps is essential hence the "brick" which it had fitted.

aja540i 1906 Report post Posted July 2, 2014 Unfortunately most of the stuff you have pulled out is stuff that doesnt use much power anyway, you will still need as close to the original size battery as possible in terms of amp hours, have you thought about running 2 smaller batteries?

francoisv 466 Report post Posted July 2, 2014 Yea I agree, like she starts up fine with a DIN55, but that is allot wider then what im after. it has the height that im after, just not the width. Will probably need to go to a battery centre of some sort id imagine..OR find another relocation point to fit the standard one Quote Share this post Link to post Share on other sites
francoisv 466 Report post Posted July 2, 2014 That could be an idea with the two smaller batteries Andrew, could connect them in series or something. Ill have a play around this weekend and see what the go is Quote Share this post Link to post Share on other sites
jeffbebe 1559 Report post Posted July 2, 2014 Yeah, I wouldn't scrimp on battery power on an E39. Trans and engine failsafes will kick in if voltage fluctuates even a little. The guy who bought mine got engine failsafe when he tried to connect an iPhone 5 instead of 4 to the little iPod thingy I'd fitted. Car didn't like it!

Haha yea I'm just re calculating another relocation point to fit the standard battery, hopefully there is enough clearance under the new floor..

yng_750 247 Report post Posted July 2, 2014 I have run a 740i on a din55. Not reccomended size but was all that was available at the time. Any smaller size than that you will be looking at a gel battery i would say. Get you bank account ready though Quote Share this post Link to post Share on other sites

We are under budget for the project so far, so I'm sure we could invest in a decent battery Quote Share this post Link to post Share on other sites

yng_750 247 Report post Posted July 2, 2014 Gel batteries have more power for the size They are gel based inside instead of liquid acid. This means they can be mounted at any angle and are much longer lasting. expect to spend 400-500 from what i remember Quote Share this post Link to post Share on other sites

I'll take a drive down to the auto battery place in Albany tomorrow to have a look at what they have. If it's gonna save me time and space, then $500 will be worth it I guess.

francoisv 466 Report post Posted July 2, 2014 Thanks lads, ive just emailed them with the details of my standard battery VS what will be needed to run the new engine and setup etc, will see what they say. I have some heavy duty audio gear I rad in my DB drag car that I will be using to help with the power load etc, it worked wonders in the other car Quote Share this post Link to post Share on other sites
