Recharge 9V Battery on Device Without Affecting Electronics

[Anthonytsi]

I have a device that I am working on and am stumped.
This device runs off of a 9 volt rechargeable battery that is difficult to access to recharge.
I would like to retrofit a plug into the device that would allow me to charge the batt without the electronics down line of the batt getting any power while charging.
This would keep me from having to remove the batt every time I need to charge it.
Any ideas?
Thanks in advance.

just add a switch that switches the battery output from the circuit to the recharger.

Use a switching jack to remove the battery's connection to the circuit when the charger is plugged in.

When the charger plug is inserted the switch is opened. You can find them in most appropriate jack types.
