Light weight battery??
Discussion
My 2.0 tuned Duratec came with a tired 44ah battery which needs replacing.
Does anyone know if there are any lightweight batteries that will do the job?
I don't want to use a booster pack every time, but I just figured with all the lith-ion tech now that perhaps there is a lighter option?
Cheers

A few people have changed to Magneti Marelli batteries which come in under 2kg but the cost is just under £200 on eBay. The dealers actually advertise Caterham usage so they should be easy to find. You may need to factor in the cost of a suitable charger and some form of mounting bracket too.
Lighter batteries are available (see here for instance) but the cost rises as the weight lowers.

This may be worth a punt!

Following this with interest for my Duratec Westfield (sorry). Currently run a 20AH lead acid off a golf cart of all things, which has been absolutely fine. Want to go lighter, but the specs of LiON batteries are confusing...
The advantage of the lithium ion battery is that most of the capacity is available at the rated voltage so you don't need the same capacity as a lead acid battery. 10 Ah is OK for a Caterham - about 1/3 of the lead acid capacity needed to give a similar performance. Also worth saying if you get one, don't trickle charge them as they last much better if stored in a part charged state.Everything like fuel pump fired up as normal, but when you turned key fully it gives a single click (as if starter is stuck/battery is flat), then car goes dead.
You then have to take key out to re-set , or disconnect and re-connect the battery to try again as if some security has kicked in.

Agreed.
I am trying to fathom specs for batteries but it seems there is no real agreed convention, or if there is manufacturers seem to keep some specs secret!
It seems you can choose a selection of values for calculating Ah and they can vary by a factor of 5!
If anyone does find out a Life battery that works please let us know.

I fitted one of these and it has been brilliant. Massive cranking power and it weighs virtually nothing. Just don't let it go flat.
