The first battery lasts forever, the second one only lasts a good 2 years. Despite being fully charged 2 weeks ago and also driving several times 50km, the thing is now flat. I just ordered a gel battery. I will shortly report on the experiences. Weighs 2kg less and has now 12AH instead of 10AH. What surprised me: Price is about the same as with the conventional battery. 1.00 x Battery SHIN YO GEL-12-BS (CTX 12-BS) ID: 8712212 EUR 48,24 ————————————————- ————— Shipping costs: 0,00 EUR ———————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————–
