Battery Pack :
Battery Pack for two AAA batteries with 2 soldering contacts:
Battery :
2 pcs. of AAA alkaline batteries !

Remarks :
1. Battery life time in IDLE mode is approx. 4 month (depend on use). You can use small switch to switching between SLEEP mode and IDLE mode, so battery life can be increase up to 3 years (depend on use).
2. You can use PDAwin IR transceiver separately from your PDA up to range approx. 1 meter.
