How to replace it

1. Use a marker to draw a + on the long contact and a – on the short contact. Take the pack out from the house and tear the + & - off to separate the terminal assembly out. Be care for the 2 tiny black wires which connect the temp sensor.

2.Clean and tin the 2 contacts with solder paste.

3. Insert the green temp sensor into the middle of the new pack. Put the rubber ring on the cells to locate the terminal assembly. Solder the short contact to + on the new pack AT FIRST. The soldering should be done in less than 10 seconds to avoid heat damage to the cell.

4.Take the rubber ring off and then solder the long contact to – side on the new pack. You may install the new pack back to housing now!
