This is a good way to set it on fire.
The charging sw / hw is now not valid.
Sometimes you can parallel identical cells of the same age and condition, it's a seriously dangerous idea to directly parallel two Lithium Ion cells, especially if different ages, manufacture or capacity.

So also only replace cells with the original type. This applies to everything, except cells / batteries only recharged externally in a programmable charger. Note there is also a fire risk using any sort of rechargeable battery/cell in equipment ONLY intended for single use disposable cells due to lack of fuses, protective circuitry etc.
