Quick Charge NPEXU - Manual (Page 2)

QUICK START INSTRUCTIONS:
The No Polarity chargers do not have positive and negative
connections. The two clips may be connected to the battery(s)
either way. Move the switch to the OFF position. Before making
battery connections, be sure the charger voltage matches that of the
battery(s). Once connected, the green battery LED should lite. If
not, see the trouble shooting section before proceeding.
Plug the charger into AC power with the same ratings as that of the
charger. (See decal). Move the switch to the voltage that matches
the battery. The red LED should lite, and the ammeter should
deflect to the right or left of 0. As the battery becomes charged, the
meter will work its way back to 0. The charger may be left on, and
will maintain the battery(s).
While the charger is on, it will adjust the voltage applied to the
battery depending on the air temperature. As it increases, the
charger will lower the voltage, as the temperature falls, the voltage
will rise. This optimizes battery life.
To discontinue charging, move switch to the OFF position .
