1 Safety Precautions 1.1 Read Before Installation 1.2 Important Note! Observe the following precautions at all times. Batteries are no more dangerous than any other equipment when handled correctly. � Keep batteries upright. � Acid is corrosive - wear protective clothing, rubber gloves and goggles when handling batteries and electrolyte. � Do not allow metal objects to rest on the battery or l;all across the terminals. Never wear rings or metal wrist bands when working on batteries. � Do not smoke or permit open flames near batteries or do anything to cause sparks. � Do not spill acid on the skin or clothing. If acid is spilled on the skin, wash immediately with copious amounts of clean water, then cover with dry gauze. If acid comes into contact with the eyes, flush with clean water for at least 15 minutes. In all cases, obtain immediate medical attention. Cells supplied filled with acid must be placed on float charge or given an equalizing or freshening charge within 90 days from the date of shipment. Failure to observe this requirement could result in permanent damage to the cells. 2 Unpacking and Inspection 3 Storage Upon receiving a shipment of battery cells, it is advisable to open the shipping containers and carefully check the cells and hardware against the packing list. The contents of each consignment are carefully inspected by Alcad Incorporated before shipment. Any damage should be reported immediately to the carrier and the damaged items retained for inspection by the carrier's representative. For cells supplied filled and charged, check that the acid level in all cells is at or just below the "MAX" line. Any spillage should be replaced with pure dilute sulfuric acid with the correct specific gravity (see Section 4.1). It is essential that filled and charged cells be placed on charge within 90 days from the date of shipment. This is to prevent irreversible sulfation of the plates and permanent loss of battery capacity. Cells supplied filled and charged should ideally be placed on float or trickle charge until required (see Section 7 for charging details). This charging should be carried out with the shipping containers open, or the cells unpacked, and with adequate ventilation to disperse the gases formed on charging. -1-
If continuous charging is not possible, the battery should be given a freshening or equalize charge (see Section 7.2) at least every 90 days and whenever distilled water is added (see Section 9.3). Cells supplied dry charged may be stored for an indefinite period, provided that they are adequately protected against condensation and the effects of high humidity. 4 Filling Dry Charged Cells 4.1 Acid The following table gives specific gravity data at 77°F (25°C) for fully charged cells with the electrolyte at the maximum level: Nominal Sp. Gr. Specific Gravity Range -2- Sp. Gr. For Filling Dry Charged Cells Cell Type 1.210 1.200 – 1.220 1.200 SGL, SGH 1.240 1.235 – 1.250 1.225 SD, SDH, PMF 1.300 1.290 – 1.310 1.295 * *For special applications only. Pure sulfuric acid diluted with distilled or de-ionized water to the correct specific gravity (see chart) is required for filling dry charged cells. If the acid has been provided by Alcad Standby Batteries, store it in a safe place until required. If acid is purchased locally, it should conform to Federal Specification OS-801C. If concentrated acid has been obtained, it is essential for it to be diluted with distilled or de-ionized water before being put into the cells. Plastic mixing tanks are ideal for this purpose; if glass is used, care must be taken to limit temperature rises due to the heat produced in the mixing process. Do not use metallic mixing tanks. When mixing acid, always observe the following safety measures: � Wear protective clothing, gloves and goggles whenever acid is handled. � Make sure the mixing tank is perfectly clean before use. � Put the water into the mixing tank first. � Then add the acid, slowly and cautiously, stirring continuously. WARNING NEVER ADD WATER TO ACID OR IT WILL SPLASH DANGEROUSLY � Allow the mixture to cool to room temperature before pouring it into the cells. Concentrated acid is normally available with a specific gravity of 1.835 or 1.400 at 77 F (25 C). CAUTION DO NOT PUT CONCENTRATED ACID INTO THE CELLS OR THEY WILL BE RUINED.
