Reconditioning The Battery; Checking The Alternator - DeWalt DXAEC210 Instruction Manual

Reconditioning the Battery

Periodic reconditioning is recommended to maintain a battery's
optimum performance. Battery recondition sends a series of electrical
pulses to break up the crystalline form of lead sulfate and turn these
chemicals into useful battery electrolytes.
1. Refer to the "Charging the Battery" section of this Instruction
Manual. Set up the battery charger and connect to the battery
following steps 1 and 2. The unit will be in Standby Mode.
2. Press the Battery Recondition Button once. A beep will sound and
the Digital Display will show the following:
The Battery Recondition Indicator and the Battery Icon light solid.
The Battery Recondition Icons flash, and the bars on the Battery
Icon change from solid to empty (top to bottom) repeatedly.
The process stops automatically after 24 hours. To end the process
sooner, press the Battery Recondition Button once again to turn it
off. A beep will sound and the unit will return to Standy Mode.
More than 24 hours may be needed to restore performance on
some batteries. If so, repeat the process.
3. When disconnecting the battery charger, unplug the AC Power
Cord, and then disconnect the battery charger from the battery
following the last step of the appropriate set of directions in the
"Preparing to Charge" section of this Instruction Manual.

IMPORTANT: If 5 cycles of reconditioning does not improve battery
performance, discontinue and recycle the battery.

Checking the Alternator

PART 1
No Load (turn OFF all vehicle's accessories): The vehicle battery
must be fully charged before testing the alternator. Run the engine
long enough to achieve normal idle speed and verify there is a no-load
voltage.
1. Refer to the "Charging the Battery" section of this Instruction
Manual. Set up the battery charger and connect to the battery
following steps 1 and 2. The unit will be in Standby Mode.
2. Press the Alternator Check Button to start the check. The Digital
Display shows the following to indicate the unit is analyzing the
alternator:
The Alternator Icon will flash and the Battery icon with two bars will
light solid.
