Operating Instruction
ACTIVATION AND CHARGING SEALED MAINTENANCE FREE BATTERIES (YT & KT TYPES)
- Place the battery on a level surface. Battery must be out of the vehicle.
- Remove electrolyte container from vinyl bag. Pull off the strip of caps. Put the strip aside-you’ll use this later as the battery sealing plug. Use only the dedicated container that comes with the battery. It contains the proper amount of electrolyte for your specific model-important to service life and operation.Do not pierce or otherwiae open the sealed cells of the electrolyte container. Do not attempt to separate individual cells.

PREPARATION FOR ACID FILLINGTake off sealing tube (usually red color attached to vent) and remove filling plugs-right before filling with electrolyte. Replace the short sealing tube pulled off from battery vent elbow with a long exhaust tube.
FILLING ELECTROLYTE (ACID)Fill battery with electrolyte (dilute sulfuricacid) with a specific gravity of 1.265 at 68 . Fill to UPPER LEVEL as indicated on
battery. Electrolyte should have a temperature between 60 and 86℉ before filling. Leave battery standing at least 30 min.
after filling. Acid level may have fallen during standing. Refill acid to UPPER LEVEL before starting charge.
CHARGINGPlace battery on charge for 3 to 5 hours at approximately the current equivalent to 1/10th of its rated capacity. The battery can take a quick charge at a higher current up to the maximum current of 3/10th of capacity. However, a quick charge can only be taken by surface area of the battery plates, while lower current can charge the battery uniformly. If electrolyte level has fallen after charging, fill with clean drinking water to UPPER LEVEL. After water is added, continue charging 1 to 2 hours to mix water with acid. After charging, replace filling plugs firmly, wash off acid spillage with water and dry battery case. Make sure the battery terminals are completely clean of any acid substances.
Do not use sealed tube (red tube) once battery is filled with acid. Using sealed tube (red tube) after acid filling may cause explosion.
- CHECK ELECTROLYTE LEVEL (not required for)sealed maintenance free batteries). lf the electrolyte level is below the tops of the plates in any cell (or the lower level line) refill with clean drinking or distilled water to upper level line.
- Keep the battery clean of all acid spillage and dirt, especially around the terminal area.
- Keep the exhaust tube free of any kinka or dirt build-up.
- lf the vehicle is not used frequently the battery will require additional recharging. Specific charging rates or times vary
because of the following:
- Battery's electrical capacity
- Temperature of the electrolyte
- Battery state of charge at the start of charging
- Battery age and condition
- Type of charger
- Check the specific gravity of acid or the voltage of the battery to make sure it is at a100% charged condition.
lf not, additional charging is required. Seecharts below for battery test readings using either a hydrometer or a voltmeter.
