Recharge monitoring guidelines
One of three things will occur during charging:
If the battery terminal temperature exceeds 18°F (10°C) rise from ambient, this indicates the battery
has no useful life left. Stop charging and replace the battery.
If the battery voltage does not reach 10V (power supply switching to CV from CC Mode) within five
hours, then the battery is not taking a charge. Stop charging and replace the battery.
If the battery voltage has reached 10V within five hours, stop charging and reconnect the battery to
the A704-5. You can then top up the battery using the A704-5 external charging
adapter. (When using the external charger, a full charge should be attained after only a few hours.)
For best results you should only begin using the A704-5 after it has been fully charged.
