Different Battery!

Post by Steely »

I need to use a different battery on my KR-1S, due to relocating it, just need a bit of info on ratings.

Standard battery...

CCA (cold cranking amps-approx):
50 cca

Amp/hour rating (approx):
4 amps/hr

Voltage:
12 volts

Battery i would like to use...

CCA (cold cranking amps-approx):
35 cca

Amp/hour rating (approx):
2.3 amps/hr

Voltage:
12 volts

Can this one be safely used?

Any feedback would be greatly appreciated,

Tony

it doesn't mather what battery you put in , a KR doesn't even need one.

if it is for road use : if you switch the lights off, it'll start without battery (if you leave them on, he will be difficult to start).

but you better one in anyway, even if it is only a very small one, just so it can take the current made by the alternator.

so put in whatever you like :wink: I'm running mine with a complete dead battery for years now. can't be bothered to spent money on it.
My ultimate goal is to die young as late as possible !

The Kips motor runs through a cycle when you turn on, but don't suppose it'll do any harm without it.

Probably trying to turn cold valves is what causes them so many problems :-k

I'm not saying what Jan has done is wrong, but the rectifier needs to be ended somewhere otherwise it over heats and will eventually fail.

That white wire is unregulated and is the outlet for all the extra power that the regulated side is not using and this prevents the regulator from getting too hot.

The battery acts like a big sponge for it.

Having said that the battery size is only really relevant if you have a starter motor or a high demand system like fuel injection, which KR's don't.

I guess Jan has a battery that is able to accept charge and not hold it, but you might not be so lucky. If it won't accept the power generated by the generator the only place it can go is heat in the regulator, and this will kill the regulator eventually.

The smaller battery will be fine for the KR electrical system.
