Hardware clock is losing time

Found the battery and it tested at only 1.8v so that is most likely the issue. I requested one from Mladen but he is still waiting on a response so I rush ordered this 3v battery but it is a CR2032 vs a CR1620 will it still work? The only CR1620 with the wire leads I could find was on Alibaba but you had to order 1000 of them.
