1. The battery has triggered certain protection states (low-temperature/high-temperature protection, over-current protection, etc.), preventing the battery from being fully charged. 2. Mismatch between the parameters of the charging device and the charging parameters of the battery, leading to the inability to fully charge the battery.
Unfortunately, when your Lithium-ion battery can not be fully charged, there could be a variety of reasons behind the problem. The issues might stem from a damaged battery or external factors unrelated to the lithium battery itself. It may require some trial and error as well as battery troubleshooting to uncover the underlying cause.
While there are numerous reasons why rechargeable batteries might not be holding their charge, the bottom line is they don’t last forever, even in ideal environments. With every charge and discharge internal chemical build ups reduce their ability to charge making their discharge times shorter and shorter.
Here it will seem like the battery isn’t holding its charge, but in reality it is never really being fully recharged and you will need to plug it in to a wall charger from time to time to get it back up to a full state of charge. Lead acid vehicle batteries that are never fully recharged can also suffer from acid stratification.
In short, connecting batteries of different voltages in series will work, but damage will be done to both batteries during the discharge and recharge cycles. The more one is damaged, the more the other one will be damaged and both will need replacing long before needed.
In a huge battery pack like in EVs or solar arrays the cells are distributed over a waste areas and there might be temperature difference among the pack itself causing one cell to charge or discharge faster than the remaining cells causing an imbalance.
