It broke just from pushing it to start it

Thank you very much for taking the time to write to me.
I know it's hard to understand me without demo video.
The battery is new, (yhuasa 12N14 - 3A).
As it was three months without use, I connected a power source to get more revolutions at startup.
Now the bike works properly.
I am afraid that something that was left without proper repair will suddenly break.
Thank you very much and sorry again for the translation.

 

It’s not uncommon for a new battery to be a bad battery. Sounds like yours is a bad battery even though it is new.

it IS also possible that you left a key on, or possibly had the key turned to the “locked with lights on” setting and drained your battery.

 

Good observation, I'm going to check if the circuit has any leaks. Good date

 

Plus one on the new battery being bad. My last replacement was bought new this spring, was sluggish from the get go, and crapped out after a few months. It tested fine on the bench, but for some reason won't hold a charge very long, and has from the beginning cause sluggish cranking.

Next time I think I may try an AGM battery.

 

.." It wouldn't be the first new battery I've seen go bad "...

 

I bought a good brand battery about 6 months ago, then the motorcycle was stopped for 2 months, currently I made measurements of the alternator charge. The voltage regulator cuts fine. Battery voltage doesn't drop much when cranking. For now it is in the normal parameters.
Good luck with the purchase of AGM !!

 

To rule out electrical damage, I made the measurements and the alternator load, the voltage regulator works correctly.
