What is best battery replacement for the F10 M5

[gh0stt_m5]

Turned out to be a bad battery after all. Thankful it was a minor fix. Heard it doesn't happen too often. Thanks for all of the suggestions!

I accidentally drained the battery after leaving car parked one week with no trickle charger......it has not performed well ever since....shorter reserve time and less crank juice.......just bought a new one and will make sure to trickle charge with the optima charging unit.....should be fine since I've had the battery on other cars with good success

Do you need to do anything to make this Optima fit? Their site says they don't have a direct replacement for our car. Thanks.

no there is a bolt on bottom metal holder that fits right in to secure battery....Optima is holding up nice

allmotor,

which one are you using?

$1200 to shave a little weight? Now that’s dedication.

Thought the zero at the end was a mistake, the lithium batt suppliers are making a packet.

They are up to $1541 now
Best battery for an f10 would be an ODYSSEY Battery
