Battery Chargers
The battery chargers have the following features:
• Front panel LED battery charging/failure indicator.
• Automatic “battery care” recharge cycles to ensure a maximum charge.
• One or two batteries fully charge in 90 minutes if the system is not operating; 4 to 5 hours
while unit is operating.
• Individual battery chargers for each of the 2 batteries so that a bad battery will not degrade the
other battery. Will not prematurely “kill” batteries.
