1.1 Battery information
This instrument runs on a Lithium Ion battery which should be maintained to maximise health, reliability and
longevity. There are a few simple things that you can do to help maintain your battery health and power potential.
1. Allow your battery to charge fully before using the instrument. Fully charging the battery before use will
ensure it can perform at peak performance and make maintaining performance easier.
2. Keep your battery charged up whenever possible while in use. A Li-Ion battery prefers frequent top-ups and
should never be left in a flat state for extended periods as this can cause permanent damage.
3. Maintain a charge during storage. If your battery is to be stored for extended periods maintain a charge of
40%, allowing for some discharge and maintaining the protection circuit.
4. Store your battery in a cool, dry place. Li-ion batteries can get stressed when exposed to heat which can
reduce its life. Do not store above 30°C (86°F) for extended periods.
