I just removed a leaking battery from a 286 motherboard, but I'm not sure if I should be connecting the replacement to the external battery pins, or to the pads where I removed the original.
Testing the pins on the external battery connector shows <0.2V and no charging current. So I'm assuming the external battery connection is meant for a non-rechargeable battery, like a lithium cell.
Testing the pads where the battery was removed shows 4.8V and 35mA charging current, which is pretty much spot on for recharging the 3.6V NiMh replacement battery I have.
