Entropy over time - The O.E.M. battery lasts much longer " years " , compared to an after market one. Motorcycle battery's have the same story. A Yuasa brand battery will last for years - while 3rd party ones ' might ' last for 6 ~ 8 months.
Certainly true for some aftermarkets but I think it depends. Not every is of the same quality. I've had some other Newell and Duracell baterries and they keep working fine. Nevertheless, thanks for the input 😊
