Charger is supposed to disconnect at about 4.2V, so you could measure 2.5V on a cell and it will never try to charge.
Many cells have a PCB with a controller built in. If the original had that, then the replacement needs one. If there was no built in controller then a cell should be identical.
They are the most tricky rechargeable technology.
Unless it's strange, the only absolute requirement of a charger is the voltage. 5V now and 5.2V on really old things. Even a 20A charger will still only charge at 500mA maximum if that's what the gadget takes. Only newer things take more than 500mA (1/2A). Also charge will be less at the start and end in most cases.
There is no ongoing trickle charge with LiPoly, that would set them on fire.

Interesting, thanks for the additional details. That is useful to know so then I know what to focus my efforts on. If this is just how they charge I can concentrate on how to work within those parameters rather than thinking it some problem with the individual battery.
The battery was specified as compatible with prs-300 and identical voltage of 3.7. Chinese cheapo we must take at their word but that is what they were listed as.
