Rechargeable Battery Facts
• Batteries discharge naturally over time (approximately 5% per month).
• Battery capacity (the amount of charge the battery will hold) is lower at low temperatures.
• Batteries that are charged to their maximum capacity will generate heat if they continue to be charged.
• The ProTime instrument uses a rechargeable NiMH (Nickel Metal Hydride) type battery. The maximum
capacity of any rechargeable battery will gradually decrease over time. To ensure maximum life of the
rechargeable battery, read and follow the information in Care of the ProTime Battery for Maximum
Life section.
Care of the ProTime Battery for Maximum Life
A new instrument, an instrument that is used infrequently, or an instrument with a new replacement
battery, should be plugged in for at least 8 hours before use to ensure that the battery is completely charged.
The instrument screen will show CHARGING BATTERY when the AC/DC power module is connected to the
AC power cord and the ProTime instrument. The screen will show CHARGE COMPLETE when the battery is
fully charged. The AC/DC power module should be disconnected after the CHARGE COMPLETE message is
seen. The AC/DC power module that has been supplied by ITC has been selected specifically for use with
your ProTime Microcoagulation System. Do not use any other AC/DC power module.
When the battery indicator on the screen shows less than 25% charge remaining, please refer to the
Charging the Battery section for instructions. To maximize battery life, allow your ProTime instrument to
discharge completely before re-charging. Avoid charging the ProTime instrument for frequent, short
periods of time (such as charging for a few minutes, removing from the AC/DC power module, and then
recharging again). Avoid storing and charging the ProTime instrument at extreme temperatures.
Built-in ProTime Battery Features
The ProTime instrument will shut off after 5 minutes if left unattended in order to preserve the battery
charge. If the instrument shuts off automatically, press the button to re-start the instrument. Before the
start of each test, the ProTime instrument checks the amount of battery charge. If there is not enough
charge in the battery to run a test, the ProTime screen will display PLEASE CHARGE IT. If this occurs, follow
the charging instructions located in the Charging the Battery section. Whether or not the batteries are
charged, you may continue to run tests once the ProTime instrument is plugged into its AC/DC power
module.
Battery Replacement
Refer to the instructions provided with the replacement battery. The used battery should be disposed of in
accordance with local regulations for NiMH batteries.
