Standard battery v race battery

[A911DOM]

I need to replace the tired battery in the 944 and am wondering if Im better off to shell out on a race battery which should be much lighter plus giving increased charge?

The cars only going to get used for trackdays (unless I decide to sneak an MOT on it at some point).

Whats other experience / opinions on this?

On a recent trip into Halfords, I notice the price of standard batteries seems to have rallied somewhat - is it going to be a completely false economy putting a budget battery on it despite the only occasional use?

TIA

I thought race batteries tended to be smaller because they were less powerful than standard batteries, based on the fact that they don't have to run for as long nor power lots of electrical items, nor start the car multiple times.

If you're not bothered about the cost, then some of the high-power gel batteries are significantly smaller/lighter.

These are the very fellas Ive been looking at actually - and Ive just a had an email back from their sales support.

Perhaps this is my misunderstanding but, I thought I'd been told that the race batteries put out a bigger charge, and also weigh much less so you win on both accounts.

I dont want to spend a fortune as this is only a track toy afterall.

and here is the very helpful response from the guys at Merlin Motorsport www.merlinmotorsport.co.uk) re the Odyssey battery:

Hi Dominic

There is not a recommended battery (for the 944) as such, I would be inclined to use the Odyssey 30. However smaller batteries may start the car but the issue you really need to be are of is you can not leave these batteries on the car as drain them will lead to a premature failure of the battery and with these batteries this can easily be done, they have high starting currents, but they do not have the Amp Hours to deal with parasitic drain. So whatever battery you end up with I would recommend that you remove it from the car and place it on the dedicated charger between uses.

Just so you know the background for these batteries; they were originally designed for starting only. If you use the car on the road you need to be especially careful.

I hope this is of use.

Regards

Gary
