The red one seems to have more cranking power and cold cranking then the yellow one, but the yellow seems most popular on most supras i have seen. Anyone know the main difference and which one is better overall. Thankx!

The red one is designed primarily for cranking a car.

The yellow is more of a deep cycle discharge battery... and it does well in that capacity.

If you don't drive your Supra often, I'd venture to say that the Yellow top would be better for you on the principle that it can be completely discharged (dead) and the recharged more often than the red top.

I have the red top AND yellow top in my LandCruiser in parallel for winching (selectable) and the Yellow top fares MUCH better.

The blue one. It is made to charge and sit for a long time in boats. FWIW Optima's suck in supra's. I've been though 3.

i like the Red Top personally but it died due to a power drain...made the mistake of tossing it when it could have most likely just needed a charge...faired pretty well

I guess your battery was bad, & thats why the car wouldn't start..
I use a walmart battery, & replace it every 24 months before the warranty runs out.

All you need is a regular good battery and a trickle charger , havent had a problem since , it was one of the best investments made since killing 3 batteries over the years

My brother had a red top in his 94 TT and the thing would crank over for about 10 seconds before starting, it was a brand new battery, we threw a stock battery out of a ford F150 in there last weekend that we had at my shop and it starts right up every time now lol. I think we just had a defective battery so we will be warrantying it.
