Q) The UBC Lithium battery charger has 2 gold-colored pins and the battery has three contacts. Which pins should I connect to the  battery contacts?

Ans) Use the outer two contacts on the battery, you may see as many as 4 battery contacts. The polarity (i.e. plus + and minus - ) of the battery doesn't matter as the charger circuit will detect the battery polarity and charge accordingly.
