SIL GTIS Power Systems Villager III, User Instructions, Page: 7 / 8

Precautions
Water
The Villager III is not waterproof. Do not leave it
outdoors in the rain or immerse it in water. If water gets
inside the case, turn off the toggle switch and allow the
Villager III to dry thoroughly before using it.
Heat
Cooler temperatures will improve the lifetime of the
batteries and electronics. Whenever possible, avoid leaving
the Villager III in hot locations or in direct sunlight.
Battery Failure
The Villager III contains three separate LiFePO4 smart
battery packs. When one of the batteries gets old and fails,
its internal electronics board will prevent it from charging or
discharging, resulting in sharply reduced capacity for the
Villager III. When one fails, all three batteries should be
replaced at the same time.
Do not attempt to bypass the
circuit board inside the battery and force charge a failed
battery
because it can catch on fire!
Contact power_systems@sil.org for replacement
batteries or parts.
