Charging Batteries
You can charge batteries internally or using the external battery charger (Option #820). The external charger provides much faster charging time.
CAUTION: Charge batteries internally or with the appropriate charger, a 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.
Internal Charging
You can use the E7495A/B to recharge while the test set is operating or shut down. For a fully depleted battery, charging time is approximately 4 hours if the test set is shut down, 8 hours if the test set is operating.
If two batteries are installed, the test set fully charges Battery 1 before charging Battery 2. During internal charging, the charge indicator blinks to indicate which battery is being charged.
To charge a battery internally, simply attach the car adapter or AC adapter and turn on external power.
External Charging
The external battery charger (available as part of Option 820) lets you charge two batteries simultaneously. Each fully depleted battery takes up to 4 hours to recharge.
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 is fully discharged will impair the accuracy of its internal charge-remaining indicator. When the fuel gauge error is greater than 10%, the battery should be reconditioned.
