Chapter 350
Even when the OmniScan X3 is turned off and unplugged, it draws a small amount of
power from the battery, which could completely discharge the battery in about
3 months at room temperature (25 °C [77 °F]).
2. Check the remaining charge of any stored batteries approximately once a month
to ensure that they have 40 % to 80 % remaining capacity, and recharge any that
do not. This is necessary because lithium-ion batteries self-discharge over time.
Failure to do so may render a battery permanently unusable if it falls below a
critical level (less than 1 %).
3. When you are ready to use a battery after an extended period of storage, recharge
it before use.
To extend the life of batteries
1. Anytime you acquire a new rechargeable lithium-ion battery, use it four to eight
times consecutively in the OmniScan X3, and ensure that you completely
discharge and recharge it after each use. Doing so will enable it to reach
maximum capacity, providing maximum run time.
2. After the first 10 to 15 periods of normal use (or after two to three weeks), it is
good practice to completely discharge and recharge the battery to maintain a
good run time and maximize battery life.
Frequently switching from external DC power to battery power and vice versa may
result in shorter battery life, because the charge/discharge cycles are limited
(approximately 300 cycles). Even a partial discharge and recharge of the battery
represents one cycle.
3. To maximize battery life, before charging, always run the OmniScan X3 on battery
power until it shuts down, or until you get a low-battery warning. For a shorter
recharge time, recharge the battery in the OmniScan X3 while it is turned off, or
recharge using an optional external battery charger (
Recalibrate button).
