1.4 OPTIMIZER Smart IPG Battery
The OPTIMIZER Smart IPG is powered by a Model QL0200I-A lithium-ion battery (Li-
Ion) manufactured by Quallion and has a usable capacity of 0.2 Ah. The current
consumption of the OPTIMIZER Smart IPG is highly dependent on the energy of the
CCM signals delivered to the patient.
1.5 OPTIMIZER Smart IPG Rechargeable Battery Behavior
The battery voltage of the OPTIMIZER Smart IPG, when its rechargeable battery is fully
charged, is approximately 4.1 V. When battery voltage falls to 3.3 V, the device places
itself in Standby (OOO) mode and stops performing any function except telemetric
communication with the Programmer and OPTIMIZER Mini Charger. The device will
return to normal behavior once the voltage rises above 3.4 V. If the battery voltage drops
below 3.0 V, the device disconnects its circuitry from the battery and stops performing
any function, including telemetric communication with the Programmer and
OPTIMIZER Mini Charger. The device will return to Standby (OOO) mode when the
voltage rises above 3.0 V.
It is therefore recommended to charge the OPTIMIZER Mini Charger at least every
week. Recharging is also recommended if the device is interrogated and the battery level
is at or below 3.5V. See Section 33.4 for further details on charging the OPTIMIZER
Smart IPG.
