Charge Time Needed if Amp-Hours is Known
• Find the Charge Factor for your battery in the table on page 11.
• Multiply by the Amp-Hour rating of the battery.
• Divide by the Charger Setting (either 2 Amp or 15 Amp).
• Multiply by 1,25 to get the approximate Hours Needed to bring the battery to full
charge,
Example: 15Amp-Hour (AH) Battery, 50% State-of-Charge,
2 Amp Charger Setting
[(AH x Charge Factor) + Charger Setting] x 1.25 = Hours Needed
(15 x 0.5 - 2) x 1.25 = 4.7 Hours
Charge Time Needed if Reserve Capacity is Known
• Find the Charge Factor for your battery in the table on page 11.
• Multiply by the Reserve Capacity rating of the battery.
• Divide by the Charger Setting (either 2 Amp or 15 Amp).
• Multiply by 0.73 to get the approximate Hours Neededto bring the battery to
full charge.
Example: 95-Minute Reserve Capacity (RC) Battery, 25%
State-of-Charge, 15 Amp Charger Setting
[(RC x Charge Factor) ÷ Charger Setting] x 0.73 = Hours Needed
[(95 x 0.75) ÷ 15] x 0.73 = 3.5 Hours
To keep your battery charger working properly for years:
1. Clean the clamps each time you are
finished charging. Wipe off any
battery fluid that may have come in
contact with the clamps to prevent
corrosion.
2. Coil the input and output cords neatly
when storing the charger. This will
help prevent accidental damage to
the cords and charger.
