Odyssey ER40 Extreme Racing Battery

Last one lasted 5 years. Great for for a car battery these days.. And was still working. Started cranking a little slowly. Would charge right up on my CTEK charger but decided to get my 2nd replacement in 13 years. Good price. Great performance. I sometimes go 3 weeks without starting this car and starts up no problem. Even after a few years if I don't start it for nearly a month, if I put it on the charger, it instantly shows full charge.

BATTERY HAS A 3 YEAR WARRANTY AND WAS OVER 10 MONTHS OLD WHEN RECEIVED AND IS NOT RETURNABLE - DO NOT BY WITHOUT CONFIRMING BATTERY WARRANTY DATE

I had a lightweight battery before and often needed to use a jump battery for starting. I decided enough of that let's get something that will actually start my car which is an LS3 powered Stalker kit car. I've had no problems since even with sometimes repeated starts due to a very lightweight clutch and flywheel. After a weekend of racing I find it still has a full charge which was never the case with my previous lightweight battery. The extra 10 or so lbs was completely worth it.
