Run Time with no Alternator

Post by fd » Fri Dec 21, 2007 12:22 am

Anybody know how long an elise will run with no functioning alternator, not using lights/heater etc with a fully charged battery ?

May need to recover a car some distance with a dead alt . . .

tut, stu . . . mmmm?

I think I have a spare S2 alternator in the garage if that's any use??

Was getting at least 1/2 an hour on FF this year but that was not fully charged (just some time on the jump leads). I think tut reckoned closer to 2 hours when fully charged.

I've managed just about an hour before from Kh on a 3yr+ old battery.

I would bank on 20A running just the engine.

I think the elise batteries are sort of 40Ah? So I would guess 2H would be the max; we did Nurburgring to Zeebrugge with Tut's car on no alternator and I don't think we stopped more than twice to boost charge it across jump leads from a running car for ~30 mins at a time.

Cheers,
Robin

Excellent gents - thanks - I need a couple of hours to be safe so will take a spare batt if required . . . it's an S2 Dave so if we're stuck over the festive and you're about I'll drop you a PM ref the alt . . .

As Robin says, my wire burnt out at the Ring, so we had to use Ross's car in 20-30min charge up stints to get to the Tunnel.

I was running in the middle with RainEx on the screen, so no wipers or lights and indicators, and got around 1.35hr max.
