well before i took my bike apart i had a strange issue with the battery .one night i starter her up for a friend to hear her ,started no problem.the next morning late morning if it matters.went to start her and she would'nt start and sounded like the battery was dieing .so i connected my charger got her to fire up but had to hold the throttle at about 1000 rpms for awhile or it would shut down.so i took her for a ride 80 miles after that she started every time no problem .so i took her apart to do some repairs put the battery my charger for about 2 hours and i checked the voltage on the battery and got 13.1 volts and dont know if thats ok cause when ever i checked car batterys in the past they would be around 12.6 volts.so is this good or defective?

thanks for reading

 

Should be fine, but most auto supplys will load test a battery for free, if you want real pieace of mind.

If the problem persists, you should check the regulator/rectifier and it's connector.

Honda went with a bad design and there is a lot of failure due to that. Since the r/r
controls both charging and voltage levels, in addition to converting AC current (from the
stator) > DC (for the bike's systems to use), failure can causes a whole range of issues.

If you see any sign of heat-related damage to the connector or the r/r itself, it might
need to be changed. Look for burnt/warped/melted plastic, burnt pins on the connector,
damaged wires leading to the connector and/or r/r.

Hope this helps, Ern

 

I took it to a car parts store I use to work for they couldn't test it cause there tester only went down 200 cca so it automatically failed .but one thing u said about the look is the top of my battery looks like there is cap and its all wavy from heat .I wonder if that's it

 

It does look warped on top most likely from heat .......I found a DIY on testing battery and charging systems so when its time to install back in bike I guess I will attempt the test. Thanks for your help.
