Before Using Your Battery Charger It is important to understand your charger's requirements. This section will tell you about your charger's electrical requirements and how to prepare a battery for charging. Plugging it in Electrical Shock Hazard Be sure that power cord fits properly into outlet. If not, have a qualified technician install a proper outlet. Never alter the AC cord or plug provided. Improper connection can result in electrical shock.
Preparing your battery to be charged It is important that you road and follow these guidelines while you are preparing to charge your battery. • Make sure that you have a 12 volt lead-acid battery. • Clean the battery terminals. Be careful to keep corrosion from getting in or around your eyes. • If you have a battery with removable cell caps, if required, add distilled water to each cell until the battery acid reaches the level recommended by the manufacturer.
Using Your Battery Charger For best results from your battery charger, learn to use it properly. This section tells how to set the controls and how to charge a battery in or out of the vehicle. Setting SELECTOR the Controls I SWITCHES: A 2-way switch is used to select the 2-AMP or the 10-AMP charge rate. AMMETER: I 10AMP The ammeter indicates the measured amount of current the charger is supplying to the battery.
6. Connect the clamp to the battery post and twist or rock back and forth to make a solid connection. This will help keep the clamps from slipping off the posts and causing sparks. 7. Select the charge rate with the Selector Switch then plug the power cord into a grounded AC outlet to begin charging. 8. The charger will not stop when the battery is fully charged. For this reason it is important to check charging progress frequently.
Calculating The Chart charge time Method • Marine or deep-cycle batteries are usually rated in Reserve Capacity (RC). Use the following table to more accurately determine the time it will take to bring a battery to full charge. First, identify where your battery fits into the chart. • NR means that the charger setting is NOT RECOMMENDED. • Small batteries-- motorcycles, garden tractors, etc. -- are usually rated in Ampere Hours (AH). For example: 6 to 12 AH, or 12 to 32 AH.
Maintenance and care A minimal amount of care can 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. 3.
