I don't know the exactly model，but XH414HG-IV01E seems can work with the board.

Kind of resurrecting this thread!
Recently got forced to improve on the offline version of the infamous LP! We are working on getting 6x custom mobile instruments/stations for off-grid use. Those are to be dedicated to a research team leaving this April and coming back late Aug 2018.
One of the task I'm facing with now is the RTC battery, supercap, whatever works best for this. Needless to add I (we'd) like that battery to be alive & kicking for min/max 5 months maintenance free.
I've been harassing Panasonic and two other battery mfg today, for a lead on their best offer, and ended up being given 739 different options to chose from loll
so... I'd like to hear what others have done so far to keep time, extend batt life, magic connectors, etc etc
thanks!

We're having this problem as well. The voltage isn't reversed. Any other possible causes?

I don’t have a picture now of the battery connection, but I can supply one later.
We verified polarity by powering the device up without the battery and using a multimeter. Also the panda’s backup battery V+ pad has a mark above it, so we always had that wired correctly.
We’re using the auto power-on feature in the BIOS and the LattePanda simply refuses to power up sometimes. This happens very rarely, one out of 500 times. But only with the 3V backup battery connected.
I’m working with an experianced electrical engineer on this in a professional setting. We automated surprise resets to test our LattePanda based product and that’s how we discovered this problem.
If the panda refuses to turn on we can hold the power button down and it will reset and boot.
We’ve bought about 30 LattePandas so far. It’d be great if this could be fixed. I hope it’s a bios Power-On logic problem not a hardware problem.
