LED Indicator and Charge Status
Fast charge (Red LED)
- The charger is in constant current mode.
- Charge current is at the maximum.
Final charge (Red LED)
- The charger is in constant voltage mode.
- Charge current is less than the maximum.
- The battery is normally 80-95% charged.
- The charger stays in this mode until the charge current decreases to charge termination level.
Charge completed (Green)
- The charge is stopped.
- Charge current is zero.

Charging Protection from Electrical Surges
It is highly recommended to always connect the MAXAIR Charger directly to a Surge Protection Device, adequate for all
anticipatable occurrances, during all charging activities of MAXAIR LIBs, and whenever the Charger is connected to a mains
power source.
To choose an appropriate surge protector you should consult with your Engineering department regarding specifics to your
physical plant and geographical environment. You may want to consider the following common fundamentals -
▲Indicator light – surge protectors will not last forever – when a surge protector properly diverts a surge, the protector itself can
be damaged in the process. An indicator light will indicate that the surge protector is working fine.
▲UL Rating - good surge protectors come with a UL rating (or equivalent regulatory mark for non U.S. countries, e.g. CE Mark,
etc.), a rating put out by the independent Underwriters Laboratories that tests the safety of electronic devices.
▲Clamping voltage - the voltage measurement that prompts the surge protector to start redirecting the excess electricity away
from the plugged-in devices.
▲A surge protector with a lower clamping voltage will trigger earlier, thus better protecting electrical devices.
▲Joule rating - the maximum amount of energy the surge protector can absorb. If the surge exceeds this maximum, the surge
protector will be rendered useless. The higher the joule rating, the more energy can be absorbed by the surge protector,
therefore, a higher joule rating will often indicate a longer lifespan for the product.
