Recharging a Rechargeable Battery Pak
The battery charger fully charges a connected SLA battery in about 10 hours. The battery charger
applies a high-level, fast charge for the first 10 hours that the battery is connected. If the battery
remains connected, the battery charger applies a low-level trickle-charge to maintain a full charge.
Agency approval markings are provided on the bottom of the battery charger.
To charge a battery:
1 Connect the battery charger to an appropriate ac power source (100 to 240Vac, 50 or 60 Hz). The
green LED (marked by the symbol) appears when the power is connected.
2 Connect the battery to the battery charger.
3 Confirm that the charge LED (marked by the symbol) is amber. This indicates that the battery
charger is applying a fast charge.
4 Wait at least 10 hours. Then, confirm that the charge LED is green. The green LED indicates that the
fast-charge cycle is complete and the battery is receiving a trickle-charge to maintain full charge.
5 Disconnect the battery.
A fully charged battery is not harmed if it remains connected to the battery charger. However, if a
battery is disconnected and then reconnected, the battery charger begins the 10 hours of fast charge
again. Additional battery charge cycles without discharging can reduce battery life.
Recycling Rechargeable Batteries
Recycle SLA battery paks locally according to national, regional, and local governmental regulations. If
recycling is not possible, contact a Medtronic Physio-Control representative for information or
assistance. In the US, call 1.800.442.1142.
To promote awareness of battery recycling, SLA battery paks are marked with this label:
CAUTIONS!
Possible battery damage.
Recharge the battery until the battery charger charge LED is green. Undercharging can cause battery
damage.
Possible battery damage.
Charging batteries outside the temperature range of 15° to 35°C (59° to 95°F) may cause improper
charging and shorten battery life.
Possible battery damage.
Electrical connection between battery contacts can blow an internal fuse and permanently disable the
battery.
