Lithium-ion batteries have many advantages over NiCads:
Negligible self-discharge, even after months of
storage
Environmentally friendly - no heavy metals or free
lithium
Light weight - saves 430g/15oz over NiCad battery
Lower cost of replacement battery
Self-terminating charge cycle - no battery
degradation with continuous operation
Powers an LA101 or LA102 for >3 hours
Typically 1000 charge/discharge cycles
Must be used with a special charger fitted to the
power board
Supplied as standard on new units, existing units
can be upgraded
Better end-point handling - longer warning,
controlled turn-off.
2 cells per battery, internally protected against over-current and over-voltage. 3.6V per cell nominal.
Battery voltage ranges between 8.4V and 5.5V with a linear relation between capacity and voltage. Discharging below 5.5V causes the battery protection to appear open circuit.
1,850mAh capacity, 200mA initial charge rate.
Lindos has tested these batteries for many years finding excellent charge retention over time.
