The cheapest reason would be that you have just to much liquid in your battery
In most cases, the generator itself is not the reason.
There is a voltage regulator which makes the right voltage for the battery, from whatever the generator is producing.
Did you have (or can lend) a voltmeter? A cheap one would be ok. Just connect the two wires to the battery (red on +, black on -)
switch to DC Range 20Volt. Start the engine and rev it up.
Voltage should be about 12,8V at idle and maximum 14,5Volt at high revs.
If you read more.... damaged regulator. This will boil your acid in the battery.
The cheap possibility could also be bad contact at the regulator connections.
You may clean the connectors. Also check the ground wire.
If the regulator is dead..... you will need another (new) one. Modern regulators can neither be adjusted, nore repaired.
At least not with usual home toolings.
The brand of the battery doesn't matter. Varta usually is a good, but also rather expensive one.
Good luck, Joachim
