anyone have one on a claasic, or use a motorbike one? seen one on a mates 200sx..looks good

 

Im thinking of one of these, as im going to put my RA on a diet. I have heard the standard battery is between 20 and 25 kilos and race/lightweight ones are around 10 kilos.

Does anyone have any suggestions on what to get ?

 

The famous Red Top battery will do you.
Used in motorsport for years.

Fro sale at Demon Tweeks etc. About 1/2 the weight of a stock battery.

 

whats the stand-by time on these though, especially when you have an alarm etc on the system.

 

I have been chatting to a mate who had a red top on his 200sx, and he said he was lucky to get 10 days without running the car before the battery had run out of juice. Looking at the sites, you can get different power and capacity bats. I am looking at weight saving, so for me the smallest and lowest capacity will be best. Ill keep the existing Bosch bat for day to day and charge the red top the night before, for on the track as they can be as little as 2.9kg. I think my bosch is over 20kg. Another down side with these bats, is they are much smaller than standard and this means securing them may be a little tricky, you can buy a box, which cost nearly as much as the bat, or bodge it with some wood, which is what I probably will end up doing.

 

Demon tweeks had loads of these on display the other day and i was tempted to investigate, seems like a good mod to have.
Since i use the car everyday i would need a balance of reliability / weight saving

 

For weight saving verses cost its great you will save around 10Kg on a dry cell battery for around 90GBP, but remember they are generally for track use etc so you may find they wont last as long or have sufficient cranking power over time on a road car as the demands on the battery will be higher.

Be careful to choose the correct battery for your car rather than the lightest or you may find you will be replacing it sooner than planned.

It needs the right battery lugs just for a start so that is a bit of work. A mate runs a motorbike battery but has been through 3 batteries in a year. Leaving the radio on while working on the car or the interior light on with the door open can flatten the battery.
