Battery Support System 2 Operating Instructions

BATTERY MAINTENANCE WARNING

BATTERY MAINTENANCE GUIDELINES AND PROCEDURES

To maximize Battery Support System 2 operation and battery performance and life, observe these 
guidelines:

• Place the system in the proper location.
• Charge batteries at room temperature.
• Rotate batteries.
• Condition batteries every three months. 
• Perform shelf-life tests every six months (optional for LIFEPAK SLA).

Place the Battery Support System 2 in the Proper Location

To help ensure proper system functioning:

• Place the system in a dry, well-ventilated area.
• Keep at room temperature.
• Keep batteries in wells.
• Do not place in direct sunlight. 
• Do not place near a heat source or an air conditioner.
• Keep fan vent on back panel unobstructed.

Charge Batteries at Room Temperature

Charging batteries at room temperature, 20° to 25°C (68° to 78°F), is preferred to maximize battery 
performance and life. The extreme temperature range for charging batteries is 5° to 35°C (41° to 95°F). 
Batteries charged outside this temperature range may not reach a full charge (even if charging time is 
increased) and irreversible cell damage could occur.

Note: 

Fully charge SLA batteries between uses. If SLA batteries are not 100% recharged between 

uses, sulfation (lead sulfate buildup on electrode surfaces inside the battery) can occur. Sulfation 
reduces battery capacity and may result in premature battery failure.

To charge a battery:

1  Insert a battery into a Battery Support System 2 battery well. 

CHARGE

 LED lights and charging 

begins automatically. 

2 

READY

 lights when a battery reaches full charge. The battery may remain in the battery well until 

needed. The system supplies a trickle charge that prevents overcharging and maintains the battery 
at peak capacity.

Note: 

Withdrawing the battery from the charger before a 

READY

 indication may result in an 

inadequate charge.

Note: 

If 

DISCARD 

lights, remove the battery from use and discard/recycle (refer to 

page 3-5

).

WARNING!

Possible loss of power and delay of therapy during patient care.

Using an improperly maintained battery to power the defibrillator may cause power failure without 
warning. Use the appropriate Medtronic Battery Support System to charge and condition batteries.

CAUTION! 

Possible battery damage.

Charging a battery at temperatures below 5°C (41°F) or above 35°C (95°F) prevents the battery from 
reaching full capacity and may cause irreversible cell damage.
