Appendix A: Maintaining the life of your power cells
The following table shows the recommended schedule for charge/discharge:
rating
cycle time
(recommended)
max cycle
time recharge
300mA 0-8hr 10hr overnight
For best battery life, cycle the batteries in a shallow fashion, and try to allow the cells to reach
float status before using them again. We do not advise exceeding the recommended cycle time.
If you discover that you have forgotten to turn your dAck! off for several hours beyond the
recommended cycle time, immediately switch to charge mode and allow it to reach float charge
mode before use.
As the power cells age, their maximum cycle time will get shorter. Appropriately de-
rating (shortening) the cycle time will allow more recharge cycles out of the cells. When the
maximum cycle time becomes too short for your listening habits, it is time to replace the cells.
Replacement power cells are available from Ack !Industries.
The usage schedule presented is designed for battery longevity – if you do not mind
shortening battery lifespan, you can push the cells further. The key to battery longevity is to
keep the indicator green most of the time, which means remembering to turn the dAck! off when
not in use.
