Toying with the idea of a new lighter battery. Noticed some cars using much smaller batteries (around half the size in a S2000 for example).

Anybody tried a smaller battery and are there any specific lightweight ones to buy off the shelf?

What are the differences in batteries to look out for?

Bob

 

I dont know the details/spec-but ive seen one fitted in a Spec C,and was told it was std on them.

 

Try the Optima or Odyssey ones.

 

I use a Bosch motorcyle battery on both cars. Light and big space savings too. Under £50. You coming to Elvington on 22nd?

 

yep the spec'c's have a lightweight battery.... will check make etc tonight....

 

Cheers guys.

Optima ones are around £150+. 17-20kg in weight

Spec'c'57: That would great mate

Harvey: Do you know the weight and part number of the Bosch one? Sounds good value too. I doubt I'll be going to SSO as its too far to travel. If it was somewhere close then I would definately come along.

Bob

 

anyone know what a standard battery weighs?

I run a Braille battery - it weighs 5.6kg!

Has just enough power to check compression in all 4 cylinders before it dies. Can't let the car sit for more than 3 weeks in the cold either, but thats what the jumper cables are for.

Picked it up at www.kingofimports.com

 

Harvey: do you know the spec of yours or part number?

Cheers

 

Let me know what you decide Bob as I want to do this too.

I won't want to take passengers soon as they weigh to much

Will do mate.

 

im also in the market for a lightweight battery...so will watch this thread

 

This one is 5.2kg (Braille @$150)

My Mates been running a Redtop lightweight battery now on his highly modded S14 for months, WOnder how they would stand up to Morettes Etc , seeing as they will be pulling more power than standard headlights !!!

 

Will try and get down the motor factors tommorow and see if I can get an idea of the weight of motorcycle batteries.

Bob

 

whoa, i had to strain my eyes to see that!!!

 

got a Bosch Silver from a new shape Corsa in mine, 10 quid from the local scrapyard, nowhere near as heavy as the standard Impreza one

 

how does it compare to your old one? do you run a big install (stereo)? if so do your lighs struggle when its up loud? i have a spare battery from my AXGT its much smaller than my scooby one so im going to fit it and see how it goes over the weekend.

I tried an Odyssey PC1200 without success. If the car was left standing for any length of time, like a week, the alarm & tracker appeared to drain it. This became particularly annoying when my wife needed to take the car while I was out as serious earache was generally the result The race / rally cars that use some of the smaller batteries will not experience this drain so battery life will be good as will starting performance.

Not trying to talk anyone out of a lightweight battery just suggesting that it may not be suitable for everyone.

lasts a good month or so without a charge with the alarm on, stereo is just the usual stuff, no daft subs or amps so far not had any problems

 

I intend to use a battery saver, which will be plugged in while the car is left standing in the garage. A small battery will be OK for this. My big battery goes flat after a couple of weeks if left uncharged anyway.

Damn. I dont have any bathroom scales to take to the shop with me.

 

is this battery a straight fit as my subaru one dies all the time andthese silver bosch batteries are only £30 new at costco im willing to give one a try

 

it's not as wide or tall, but still clamps down ok

 

how much do they actually weigh? and has anybody got the weight of the OEM subaru battery?

 

Typical battery for Subaru is 14.5-15kg. The Bosch motorbike batteries I use are 8.3 kg. Under £50 inc VAT.

 

Hi Harvey any where special to get these or are just just standard bike batterys?

Neil

 

Cheers Harvey. Sounds like the best option. The aftermarket ones are only 3kg lighter and cost £100 more.

Will post up the part number when I have the battery. I'm assuming that taking the OE battery spec will be suffice for the motor factors to match up a suitable Bosch motorcycle battery.

 

Why not mount it in the boot also?

 

so howcome bike batteries are so strong then?? i trust theres been so starting issues or power issues using them?
