Working with Batteries

Charging Batteries

You can charge batteries internally or using the external battery

charger (Option BCG). The external charger provides much faster

charging time.

CAUTION Charge batteries internally or with the appropriate charger, an SMBus

charger of level II or higher.

Never use a non-SMBus charger because the battery issues commands

over the SMBus to the charger to control the charge rate and voltage.

Never use a modified or damaged charger.

NOTE To ensure proper instrument function when operating the analyzer on

battery power, both of the batteries must have equal charge levels.

NOTE For maximum runtime, it is best to have approximately equal charge

levels on both batteries. The instrument will shut down if either battery

becomes fully discharged during operation.

Internal Charging

You can use the N1996A to recharge the batteries while the analyzer is

operating or shut down. For a fully depleted battery, charging time is

approximately 4 hours if the analyzer is in standby, 8 hours if the

analyzer is operating.

If two batteries are installed, the analyzer charges both batteries

simultaneously. During internal charging, the charge indicator blinks

to indicate the batteries are being charged.

To charge a battery internally, simply attach the external power supply

and turn on external power.

External Charging

The external battery charger (available as part of Option BCG) lets you

charge two batteries simultaneously. If the batteries are fully depleted,

it takes up to 4 hours to recharge them.

You have the option of charging batteries before they become fully

depleted. Doing this does not shorten battery life. But repeatedly

charging a battery before it’s fully discharged will impair the accuracy

of its internal charge-remaining indicator.
