From what I can tell it's something like this:

which is a 3.7v flat lithium ion polymer 72mAh battery. Min order is 1030 though! You can find similar on AliExpress if you search for that description. The dimensions are listed as 4*14.8*21.5mm so it'll need to be within that, or maybe the OP can confirm the battery size?

Will this be dangerous?

Anyway to upgrade to a higher capacity battery to get better life out of it? With GPS on, it dies in 2 hours and I go on 8 hr hikes.
