12R Battery Life

I gotta ask the question....

Why do Batteries seem to run flat on 12R's when they have apparently been sitting for a while?

I've gone to look at/ test ride 2 12R's lately and both have had dead batteries..
(as much as it's poor form to try and sell something that isn't actually working)... I really would like more information about this phenomen.....


Ie: is a trickle charger a MUST for a 12r... instead of 'nice to have'?

I have just replaced the ORIGINAL battery on my 12R....nice to get +10 years out of it
but
it did survive (as will the newie) hooked up to a trickle charger


bump starting a 12R is not something one does if you can help it
( as I found out .... 3 blokes and a 12R make like a Monty Python ep ... )

Thanks Smitty... You've pretty much re-enforced what i am thinking!!!

and 10 years is pretty impressive i must say!

....
Just more concerned that with efi.. battery condition is more important than with carbs....


I used to bump start my flying condom by myself.... (cbr-1000f) .... now that was a pain..... find flat space 400 metres long and run run runnnnnnnnnnnnnnnnnnnnnnnnnnnnn! Clutch out (and pray)

replaced my original battery three weeks ago went to work stoped at the gate to openup jumped back on and no starty the small batteries in 12s dont like to sit which is a problem in north QLD because for at least 3 months of the year its too bloody wet to ride just got to take a leak on the side of the road and this place floods

i'm also assuming optimum charge back through rectifier is at 5k rpm? so just running(/aka dawdling in first) around city streets might not be enough?

Replaced my 12R battery after 5 years.......they don't like sitting around doing *nothing* , so if you have a trickle-charger, bung it on.....

You live in Perth now. You can ride all year round!
