Rechargeable Battery Pack Maintenance
Many of ATi’s telemetry systems utilize a rechargeable Lithium battery pack to supply power to the telemetry transmitter. These battery packs have an internal circuit to guard the cells from over-current and over-discharge conditions which could cause permanent damage. If the battery pack voltage drops below a factory-set point, the protection circuit will internally disconnect the battery pack from the connector.
Even if the battery pack is not being used, this protection circuit is constantly monitoring voltage levels. Because this circuit draws a very small amount of quiescent current, the battery pack could be discharged to the point where the battery is disconnected. If the battery pack is not charged soon after this condition is reached, the protection circuit itself will continue to use power which could create a condition where the battery pack may no longer be able to be recharged.
To avoid this condition, ATi recommends that battery packs which have activated the automatic disconnect during use, be charged as soon as possible. Battery packs that are in storage (not being used) should be routinely charged a minimum of 3-4 times per year.
Also, remember to balance the cells in the battery pack every 6-8 charge cycles using the 2173CB Charger Balancer that was supplied with the telemetry system. This will help ensure that you achieve maximum performance and life from these battery packs.
