Warning: do not mismatch with the 602535 battery with a 600 mAh capacity but larger than the 500 mAh one (25 mm versus 20 mm). Make sure the battery size is approximately 20 x 35 x 6 mm.

I see 602035 batteries on AliExpress that claim to also be 20x35x6mm but now up to 800mAh. Those would work too for over double the original battery life?
They appear to be fake; the maximum capacity in that size is 450mAh.
