Battery replacement, which one?
Discussion
. A 2000 Chimaera 450.For cost, a standard lead acid (LA) is the best
Gell batteries are a step up
Developed for Aero industry, they are smaller, lighter and safer than LA.
They use better quality (pure lead / electrolyte gell) materials and clever packaging techniques to increase surface area.
Gains are weight (min 50%) and smaller size. Size helps when in the footwell as you gain legroom.
To add a gell battery aint cheap, and you need a UK spec one as some with be useless if flattened.
Then you need a new battery box, terminal posts to use the standatd connections so lots to consider.
I had one in the GRiff (still there) for years with no problems.
How to choose one is Cranking amps (CCA) and them amp hours (aH).
Starting power and running power resp.

Cheers Andy, now I need to know what CCA and aH????Gell batteries are a step up

Err maybe, another thread though eh? Thanks for heads up, nice to know 'some' may appreciate the effort.

CCA= Cold Cranking Amps. Peak power from full charge / to start an engine. Pulse power.
aH= amp hours. The amount of amps it can deliver over an hour / to run an engine. Duration power.
eg CCA for a Griff is about 660cca and aH is 68ah from memory.(corrected)
Roughly speaking
Gell batteries are generally built for pulse, but the quality gives them good duration anyway. A Leisure battery for a camper/motorhome goes the other way to drive you telly/lights etc. Not very good pulse but very good duration.
A PVR40 is what I recommend for road cars. Plenty of both and 50% size/weight. The car runs off the alternater on the road anyway.

I haven't used them, but when I need a replacement I was going to try these people

The 750 CCA is what appeals to me as my car lives outside and struggles in these very cold winters!
(See you at CWR on Saturday)

We've had the ABX one on the Griff for about 6 months with no issues. Damn heavy though.http://performancebatteries.co.uk/find_battery/car...

Mac - is your battery still in the depths of the footwell? You could look to move it behind the passenger seat or boot, or maybe the fuseboard behind the passenger seat? I think Adrian Venn has moved a few fuseboards there.

Yeh, it's definately on my to do next list as it was a bloody pain in the arse [well, back and neck] when we installed the Megasquirt ecu. In fact because of all the mess down there, it caused a short on a relay which took us hours to find because we doubted our own wiring, even made a seperate temporary loom for injectors to get readings we needed. Then we found it was TVR's poxy way of dumping relays on top of the battery Mac - is your battery still in the depths of the footwell?

must have cost us two days pissing about.I've got an Optima Red Top 4.2 in my Chim and it's done a great job of starting my daily driver over the winter. It's rated at 815CCA.
I've recently given the battery a hard time by running it down due to a failed alternator and 100A fuse. I recharged it using my Acccumate charger and so far it's been fine. Started fine in -0.5 this morning.

bought my Optima at http://www.batterymegastore.co.uk/ a few weeks ago, they were a little slow due to being out of stock but were the cheapest I could find. Kept me informed though so no complaints

Cool, cheers bloke I got my Optima from CPC Batteries who were in Twickenham at the time. They're now in Surbiton.

I Use an Optima Red Top, it is fantastic.
I had the same type of Optima battery on my sprint car for 8 years and it was quality hence fitting one to my Tiv 3 years ago and have not looked back, they never let me down.
These have an acid jelly and spiral cells plus can be mounted anyway up and will not leak.
I bought mine from Tayna and they deliver via courier which was really quick, at the time a great price.
