Reconditioning The Battery; Checking The Alternator; Notes Concerning The Battery Recondition Function - DeWalt DXAEC80 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 in the "Single-Bank Charging" section or
steps 1 through 5 in the "Multi-Bank Charging" section (selecting
the desired charging Bank). 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 selected charging Bank Indicator flashes. 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 corresponding charging Bank 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 (or
batteries) following the last step of the appropriate set of directions
in the "Preparing to Charge" section of this Instruction Manual.

Notes Concerning the Battery Recondition Function:

A. IMPORTANT: If 5 cycles of reconditioning does not improve
battery performance, discontinue and recycle the battery.
B. Press and hold the Single/Multi-Bank Selection Button for
one second to toggle to view a different charging Bank in the
Multi-Bank mode.
C. Press the Single/Multi-Bank Selection Button to switch the
unit to either the Single-Bank or Multi-Bank mode.

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 in the "Single-Bank Charging" section or
steps 1 through 5 in the "Multi-Bank Charging" section (selecting
the desired charging Bank). The unit will be in Standby Mode.
2. Press the Alternator Check Button to start the check. (In the
examples in "Part 1," charging Bank 1 is selected in Single Bank
Mode.) The Digital Display shows the following to indicate the unit
is analyzing the alternator:
The selected charging Bank Indicator (Bank 1 in this example)
flashes. The Alternator Icon will flash and the Battery icon with two
bars will light solid.
