INTRODUCTION
This 1Amp multi-use charger/maintainer will keep your 12 Volt lead-acid batteries, including
GEL cell and AGM charged while maintaining top performance. In addition, it can also be
used to charge your Npower powerpack and jump starter.
This unit was specially designed to charge and maintain your batteries without having to
disconnect them from your boat or vehicle.
With built in safety features such as a reverse polarity alert, easy to read LED indicators,
automatic short circuit protection, over temperature protection, and our 3-stage
high-efficiency charging process you can be assured that your battery will be charged safely
and efficiently.
This manual will explain how to use the charger safely and effectively. Please read and
follow these instructions and precautions carefully.
Three-stage battery charging:

Stage One - Bulk Charge：
The Bulk Charge delivers maximum charging amperage to "wake up" any serviceable 12 volt
battery and allows for quick engine start. The battery will then reach a maximum safe
predetermined voltage.
Stage Two - Absorption Charge:
The Absorption Charge maintains the maximum possible charge at a constant, safe and
predetermined voltage. During this phase, the charging voltage remains constant, while the
actual charging current is reduced to allow for the maximum proper internal chemical energy
transfer.
Stage Three - Float Charge：
The Automatic Float Charge feature is ideal for maintaining a battery. It automatically “tops
off” battery as needed, to keep battery fully charged.

1. Battery State – Depending on the voltage of your battery, it may take up to 10 hours to
charge. Batteries with higher voltage can usually be charged in a few hours.
2. Battery Rating – A higher rated battery will take longer to charge than a lower rated
battery under the same conditions. A battery is rated in ampere-hours (Ah), reserve
capacity (RC) and cold-cranking amps (CCA).
3. Charge Rate – The charge rate is measured in amps. A battery charged at a lower rate
will take longer than a battery charged at a higher rate. However, smaller batteries can
be easily damaged by charging at a rate which is too high for the capacity of the battery.
4. Temperature – Cold temperature will affect a battery’s ability to accept a charge.
Charging in cold temperatures will increase the amount of time required to charge a
battery.
Clean cords and clamps each time you are finished using the charger. Wipe off any
battery fluid or debris that might have come in contact with the clamps to prevent
corrosion.
Store the power and output cable neatly to prevent damage.
Occasional cleaning of the battery charger case with a soft cloth will help protect the
finish.
