Battery Power

Battery performance and safety is strongly affected by charging parameters. Maximum battery life can be obtained using the lowest charge voltage and the longest recharge time that achieves full charge between discharges. Charge times can be shortened with a penalty in battery life. Please consult with Innergy Power Corporation, Marketing Applications Department toll free at 888 737-7697, for specifics.

Float applications are those that continually trickle charge the battery and infrequently go into discharge mode. The two methods of charging Innergy batteries in float applications are as follows:

Single Stage Charger
Charge with constant current, constant voltage (CC/CV), with voltage limited to 2.2 - 2.32 volts per cell at 25°C. Temperature compensation must be incorporated according to the Innergy Charging Temperature Voltage Compensation graph. Current must be limited to 1C (C = Rated Capacity) or less. Recharge time to full charge is 40 - 70 hours depending on state of charge, current limit and temperature. This charge method has no maximum charge time limit.

Multi-Stage Charger
Charge with constant current, constant voltage (CC/CV), with voltage limited to 2.45 - 2.50 volts per cell at 25°C. Temperature compensation must be incorporated according to the Innergy Charging Temperature Voltage Compensation graph. During this charging stage, current must be limited to 0.3C (C = Rated Capacity) or less. Limit charge time in this stage according to the Innergy Charge Time vs. Charge Voltage graph. On termination from this stage, switch to single stage float charge mode or optional pulse charge mode.

Pulse charge mode is employed to obtain maximum battery life and is defined as follows: CC/CV, with current between C/10 and C/20. Charge until reaching 2.47 volts per cell, turn charge current off until reaching 2.27 volts per cell. Repeat continuously.

Cyclic applications are those that repeatedly discharge and charge the battery on a continuous basis where the battery is not left in charge mode for extended periods of time. Following is the Innergy charging method for cyclic applications:

One charge/discharge cycle per day Charge with constant current, constant voltage (CC/CV), with voltage limited to 2.45 - 2.50 volts per cell at 25°C. Temperature compensation must be incorporated according to the Innergy Charging Temperature Voltage Compensation graph. During this charger stage, current must be limited to 0.3C (C = Rated Capacity) or less. Limit charge time in this stage according to the Innergy Charge Time vs. Charge Voltage graph. On termination from this stage, switch to single stage float charge mode, the optional pulse charge mode (as described in the Multi-Stage Charger section above) or terminate charge.

Packaging Versatility
ThinLine technology utilizes space far more efficiently than cylindrical cells. It also provides a much greater degree of freedom in choosing the form factor of the overall battery pack and in matching power requirements of the application to an optimum configuration. ThinLine cells can be assembled into Flatpack configurations. Examples of some four cell configurations are shown in the diagram below.
