▲ CAUTION!

Always make sure the charge curve parameters of the charging device

are set to meet the charging requirements of the battery; never charge a

visibly damaged battery; never charge a frozen battery.

1. Connect the Power Conversion device’s charger leads to the battery.

2. Ensure the charger and battery side connections are tight.

3. Set the charger to ON

4. Set the battery to ON

▲ CAUTION!

NOT ALL CHARGERS ARE CAPABLE OF CHARGING LITHIUM BATTERIES

CONFIRM that your chosen charger is incapable of producing transient

spikes that exceed the published terminal voltage limits for the battery.

Spikes are fast, short duration electrical transients in voltage (voltage spikes), current (current spikes), or transferred energy

(energy spikes) in an electrical circuit. Voltage spikes usually happen when the AC/DC adapter is plugged in, or charge current is

cut off quickly. Multi voltage chargers are constructed using transformers that may be capable of producing spikes that exceed

the maximum ratings of the Discover AES Battery. You must ensure that the charger being supplied:

• Meets the recommended charge curve

• Incapable of exceeding Discover’s maximum terminal voltages

7.3 Open Loop Charge Curve

1. Charge at constant current to 3.4 V per cell module (Bulk).

2. Maintain constant voltage 3.4 V per cell module (Absorption).

3. Terminate when charge current drops below 2A.

4. Optional Float at 3.35V per cell module (Float).
