10.3.2 Battery Replacement
If the RealWear Navigator battery is not charging properly, replace the battery with an original
RealWear battery. If a replacement battery is being used for the first time or if the battery has
not been used for a prolonged period, it may be necessary to connect the charger and then
disconnect and reconnect it to begin charging the battery.
10.3.3 Battery Disposal
Do not dispose of batteries in a fire as they may explode. Batteries may also explode if
damaged. Dispose of batteries according to local regulations and recycle when possible. Do not
dispose as household waste. Do not dismantle, open or shred cells or batteries. In the event of
a battery leak, do not allow the liquid to contact the skin or eyes. In the event of leak or a hazard
seek medical help immediately.
10.3.4 Avoid Short Circuit
Do not short-circuit the battery. An accidental short-circuit can occur when a metallic object such
as a coin, clip, or pen causes direct connection of the positive (+) and negative (-) terminals of
the battery. This might happen, for example, when you carry a spare battery in your pocket or
toolbox. A short-circuit at the terminals may damage the battery or the connecting object.
10.3.5 Avoid High Temperatures
Leaving the battery in hot or cold places, such as in a closed car in summer or winter conditions,
will reduce the capacity and lifetime of the battery. For the best results, try to keep the battery
between -10°C and +50°C (+14°F and 122°F). A device with a hot or cold battery may not work
temporarily, even when the battery is fully charged. Battery performance is particularly limited in
temperatures well below freezing.
