What voltage should my bike battery be with the engine running and not running be?
About 13.5 - 14.5v at 3,500 rpm, 12v not running.
+1 but not running I've seen 12.80v. I've just changed the regulator on Jean's bike and it was 13.89v at tickover.
battery engine off any where between 11.8v to 12.8v running fast idle between 13.2v and 14.8v max any higher than this and u'll cook the battery any lower than 13.2v and battery will not recharge
just had to change my battery as the original started to die , had the bike nearly 12 months from new so exspected longer life ? go the battery off & put it on charge after a few hours battery still half charged so left it on over night still not charged past half ? any one know why ? and how long dose a battery tend to last on a D675 ?
put a new L F tecnology battery on ( the type you fill yourself £41 ) soon as you fill it its on 12 v fully charged but put it on optimate just to be sure .
my old bike (triumph speed trip 955i ) had same battery for 3 years no problem & i never had an optimate ,it would still start even if not used for 2 weeks .
The 09 has a higher capacity battery but the <09 has a go kart battery. Since go karts don't have fuel injection or start with headlights on then it's a pretty poor battery. We got 12 months out of the 1st battery on both bikes now one is 12 months old and the other is 2 years. I'm expecting a battery failure any minute now
guess i had the gokart type then
are these L F type any better ?
