Trying to identify this rechargeable battery

Hi there, I am trying to identify this battery. It comes out of a 120V 6-outlet outdoors timer that has an LCD display and can be programmed to have numerous different on/off times, etc. I suspect that the battery retains whatever is programmed into the timer. Unfortunately, there are no markings on the battery, nor the timer itself.

Battery is 5.6 mm thick, the smaller diameter is 9.6 mm, the larger diameter is 11.5 mm and if relevant the lead spacing is 6 mm.

I included a photo of the PCB board for reference, although hard to see, the battery was removed from the left upper side of the board (see + symbol).

Any assistance that you can provide would be great, as I have several of these devices.

Thank you!

Hello,

Welcome back.

I was not able to exactly match the size and without the voltage listed it is a tough search. I do have some similar options on the links below but i am not able to lessen the results as they all could work technically. Please look over the parts on the links below to see the closest options we have to offer.

Possible alternate
P294-ND

4 other similar.

Thank you
