4. To START PEAK CHARGE, press and hold ENTER for 2 seconds. “BATTERY CHECK, PLEASE WAIT…” will
show briefl y as TritonEQ evaluates the condition of the battery. If the battery is ready, the charge process will start
automatically at which time you’ll see a screen like shown below.

Charge capacity: This is how much capacity (energy, in “mAh”) has been delivered
to the pack during charge. For a battery which previously had some charge, this
number could be low. For a battery which had little or no charge, this number
should be higher (ideally within 10% of the battery’s own mAh rating).
Elapsed charge time: This is the number of minutes the battery has been on charge.
For a battery which previously has some charge, this number could be low. For a
battery which previously had little charge, this number should be larger.
WARNING! It is normal for NiCd and NiMH batteries to become warm during charge. Disconnect batteries
IMMEDIATELY if they become hot at any time! If batteries become overheated, it may be necessary to use a
lower charge current in the future. Never attempt to charge batteries at excessive rates, as permanent damage
could result.
5. When peak charge is fi nished, the screen will show “END” and tones will sound for 10 seconds. The charger will
automatically go to trickle charge at this time (see the section below for details), but the battery should now be ready for
use. Other data measured during charge can be viewed in the DATA VIEW screens, as shown on page 14.
CHARGE TIPS: Using a
current which could fully charge
an empty pack in 1 or 2 hours
should avoid overheating of the
battery. This table shows
recommended 1 and 2 hour
charge current settings for
batteries of different rated
capacities.
DISCHARGE TIPS: More
accurate mAh measurements
can be achieved when using a
current which can discharge
the pack in 1 or 2 hours, as
shown in the table. Note: The
maximum discharge current is
1 amp. And, the maximum
power dissipation during
discharge is 5 watts, which
might cause discharge currents
to automatically be limited for
packs having high voltage.
