I would check first to see if the battery is being adeqautely charged
by the Chinese charger. Charge the battery in situ, and then
remove it, and do a discharge test, and see how many mAh it supplies.


** I reckon you have nailed it.

That charger is meant to bring a 500mAh cell up to full capacity in
about 12 to 24 hours and hold there it will a trickle of about 30mA.

If used with a 2300mAh NiMh cell, it will never become fully charged.


I would think the Chinese charger sense the voltage of the cell, not
counting the number of mAh put into it.

** More likely, it does neither.

Its just a blocking oscillator with a TO92 transistor, no chip - no smarts.
