Battery behavior plausible?

Hello, would like to hear your opinion about my gel battery (BJ unknown). Here’s the whole story: 4 weeks ago Ignition with handle heating started, starting was no longer possible (but still gelled), after pushing then again i.o. The BC data went on reset. For 4 weeks the following routes between the start operations: 30km 30km, 30km, 150km, 30km, 30km, 150km, 25km, 1km, 25km, 10km, 10km, then 2 days of service Had then a wackler at the rear t found and went out today, and I hit the ignition, so about 30 seconds without any consumer. Strangely, the rear light didn’t turn on when the ignition was fired (was not sure if it was supposed to work at all), so I wanted to start the machine. It started, after 2 seconds again. After that, it didn’t turn on again, but it was still inflated or was not completely dead. However, the voltage at the repeated start attempt has collapsed to such an extent that days After 30 minutes the charger showed 75% charge and after only three hours the charger showed 100%. Charged with 2A. Especially this section is very Spanish. Battery is installed again, after the charging process was 12.65V. Motorcycles started directly, speed depending on the idle speed approx. 14V, at higher speed slightly more (15V) With 3000 revolutions). So I assume that the Lima and controllers are still OK. Two, three times started and with everyone starting the battery voltage went down by 0.1V. Seems normal to me. Have a bigger tour tomorrow and ask me: Is the broken or just old and too much short distance? My car has always made relatively little of this and motorcycle batteries I can hardly estimate because of lack of experience. In case of emergency I could exchange the tomorrow morning, but that would be there nn such a Hauruck thing where I would have to buy lower quality expensive on site. I prefer to order there much online.
