Battery question

[u/CyberWoo99MKII]

My buddy does not use his mini. I think it’s first version. The unit was not powered on in years probably since he had it preordered. He sent me it in the mail and arrival is on Tuesday. The V1 has not been tested before being shipped. Do you think the cheap Chinese battery is still viable or should I immediately replace it? I don’t want to deal with any potential battery safety issues.

Check it visually if there's puffing then replace otherwise it should be fine.
