Thanks for the fast response.

If I do need a new battery, I'm going to go for the lazier option of buying a ready made rechargable battery from prontowizard.com or prontobattery.com.

My main question now is whether my problem is with the battery or something else.

Do you recall did your battery stop working immediately or did it gradually occur over a period of time?

Do you remember if you still could use the remote on the base while the battery was dead?
