Battery
The instrument is powered by a Li-Ion battery, which under normal use requires no maintenance. The
battery is a standard Bosch Li-Ion battery.
The battery is equipped with a thermal sensor that only allows charging within a range between 0ºC
and 45ºC (32ºF and 113ºF). This ensures long battery life.
A substantial drop in obtainable measurements on a fully charged battery indicates that the battery is
worn out and must be replaced.
For your safety
Do not expose the battery to heat or flames: Danger of explosion. Do not place the battery on a
heater or expose to direct sunlight for long periods.
The battery can be stored within a temperature range between -10°C to +60°C (14°F to 140°F), but
we recommend storage between 0°C to +30°C (32°F to 86°F), due to lifetime considerations of the
battery.
Allow a warm battery to cool before charging.
When handling or storing the battery take special care to avoid possible short circuiting the battery
contacts.
Do not insert the battery in the charger if the battery is cracked. Using a damaged battery may result
in electric shock or fire.
See further details in the battery user guide.
Safety precautions:
•
The battery should be protected against impact. Do not open the battery.

Due to environmental protection do not dispose the battery with household waste.
Battery charger
A battery charger is provided as a standard accessory for charging the battery from the mains. The
battery charger comes in two models:
•
Bosch AL1130CV, 230V AC, 50/60 Hz

Bosch BC330 Fast Charger, 120V AC, 60 Hz
The battery will be fully charged in approx. 45 minutes.
Due to the intelligent charging method, the charging condition of the battery is automatically detected
and the battery is charged with the optimum charging current, depending on battery temperature and
voltage.
To recharge the battery, first make sure that the RetroSign GRX is turned off, remove the battery from
the handle and insert it in the charger. Make sure the battery and battery charger is clean and dry
