PRECAUTIONS FOR HANDLING SEALED LEAD-ACID BATTERIES - CONTINUED REQUEST (6) In applications requiring more than one battery, first connect the batteries together and then connect the batteries to the charger or the load. Be careful to connect the (+)pole of the batteries to the (+) terminal of either the charger or the load. Improperly connecting the batteries, charger, or load may cause an explosion or fire to occur. In some cases, bodily injury may occur. (1) Dropping a battery may cause a strong physical shock that may damage the performance of the battery. (2) Confirm the life of the batteries using the real load and charger. Differences in the charging and the discharging conditions may cause a big difference in the life of the batteries.
(7) When handling the batteries, wear steel-tipped shoes to prevent possible injury to the feet if the batteries are accidentally dropped.
Tools such as wrenches used to install the batteries should be insulated. Bare metal tools may cause an abnormal short circuit accident to occur resulting in bodily injury, damage to the batteries, explosion or fire.
Do not install the batteries in a room without ventilation. The batteries tend to generate an inflammable gas upon excess charge resulting in an explosion or fire if the room is closed.
Do not contact any plastic or resin (*) which contains a migrating plasticizer with the batteries. Furthermore, avoid using organic solvents such as thinner, gasoline, lamp oil, benzine and liquid detergent to clean the batteries. The use of any of above materials may cause the containers and /or the covers (ABS resin) of the batteries to crack and leak. This may cause a fire in the worst scenario. Need to make sure the use of material will not cause the containers and/ or the covers (ABS resin) of the batteries to crack due to the migration of plasticizer within the material by asking the manufacturer of the material if necessary.
Examples for plastic or resin which should be avoided using; Vinyl chloride, Oily rubber. Examples for plastic or resin which is proper for the use; Polyolefin resin such as polypropylene, polyethylene.
Always use such as rubber gloves when handling batteries with the voltages higher than 45 volts in order to prevent severe bodily injury from occurring.
(3) Do not install the batteries in areas where they may come in contact with water. If the batteries come in contact with water, an electric shock or fire may occur.
(1) During unpacking, handle the batteries carefully and check for cracks, breakage, or electrolyte leakage. Failure to handle carefully may result in damage due to physical shock.
When the batteries are being mounted in the equipment, consider the best position for easy checking, maintenance and replacement. In addition, the batteries should be located in the lowest part of the equipment as possible. The Rechargeable Sealed Lead-Acid batteries, mentioned in this document, are designed for use in any position, but charging the batteries in the upside-down position should be avoided. When these batteries are charged excessively in the upside-down position, leakage of electrolyte from the rubber vents may occur. The upside-down is shown on the left side of the next drawings. In this upside-down position, the mark "Panasonic" on the battery are turned upside down. The drawings are only for explanation of the battery's position; therefore these are not equal to
the real appearance of the battery that specifications describe. Can be used in the vertical position and the down position (maximum angle of 90 degrees the normal position).
(3) Do not carry the batteries by picking up them by their terminals or lead wires. To do so may damage the batteries.
(4) Be careful not to jolt the batteries as it may result in damage to them.
