Batteries

I am looking at a bike with 36v battery, I have an extra 33v battery from another bike can I use this battery as a spare? Thx

I think you can if you can change the wire between the bike and the battery .

Are we sure it's not just a battery rating issue? How do you know it's a 33V battery? Can you count the cells?
