Best race battery
 

as title really, seem to be a few to choose from - so what has a good life span and wont lose a charge and lightweight. suggestions/experience welcome. thanks.

Braille Batteries

ive got a cheapy rmd one atm which ill be fitting in the next few weeks
was in my mates daily and he never had problems
his starter died and he thought battery had (tbh i did too lol :oops: ) so bought and oddysey and it was going spare so i nabbed it

the oddysey seems to have a much better starting ampage though
im hoping the rmd will be man enough for some silly compression ratios soon

Lithium ION batteries are the way forward, lighter then gel and alot more powerful

I had an odyssey in my old black Saxo and and a fair few issues with it going flat, I have to admit I wasn't impressed.
Especially when I compare it to the Varley red top in my brothers clio! It's been in the car for most the build of the car, the 4 years it's been on the road and even with very little use, it's never needed charging and it's always started first time!
It is getting slightly lazy now in its old age, but that's to be expected.
I'd really recommend them.
I'm tempted by a lithium ion one like josh mentioned for the yellow car though as its a lot lighter

race battery for road use ?
WHY
you can lower the weightby fitting a better quality smaller battery --EG honda type R battery and never have any problems for around £50
the total weight saving effect on car performance is so small .
add to that the known problems of ALL race type batteries in a road car situation and extra cost
car makers would fit them if there was a real advantage to economy ,and the volume they could buy them in would make the price very little diffeent for them to a std battery .

only reason im going is space
dont want to relocate but i need a very small battery to allow room for a few other things

mind its a track car so no real road use lol

I'm buying a bike battery, half the weight of a car battery and pretty cheap.

Lithium ION is also half the size of a gel battery. Win win situation tbh

Because we don't know the tricks and cheats like guys like yourselves do. I'll look into smaller batteries. What's the minimum you think you would need power wise?

BUT twice the price... or more!!

Well... If your spending £50 you might as well spend £150 :D lol

I posted in the track car section as it's not for a road car hence why i want something that will hold a charge and not go flat at the drop of a hat.

This!!

I would suggest using a trickle charger if your using a wee battery, just to keep the battery fully charged if the car isn't being used alot.

Braille get used in a few competition vehicles i see but they aint cheap

typr R batteyr is same length as std one but about half the width and same output as std --fits behind passenger seat no problem

charging cycle life is tiny compared with gel and acid batteries though

Not really, they are the same as phone batteries and I have no issue charging my iPhone up a million times a day lol

I run a red top 25 in the 106 and it's genuinely awesome. Went weeks without being touched (like 3 months) and starts on the button as if it was just charged.

When it eventually dies (it's about 3 years old now), I'll replace it with a lithium ion one like Josh's - even smaller, even lighter, and more powerful. Oh, and cheaper too. Absolutely no drawbacks as far as I can see, unless you're running a large stereo or something, in which case battery weight isn't your problem :p
