Battery replacement for GPS Logger (Columbus V990)

[T_guttata]

Hi

After 9 years I would need to replace the battery of my GPS Logger (Columbus V990). Sounds simple, but: how do I find a suitable battery?

I only know the size, which is 49x39x4.7mm. I'm not familiar with the details of batteries and standardization. Could anyone help me to find a suitable battery?


Thanks for your help.
