31、ENT FOR BATTERY BA-5590/U INTRODUCTION The purpose of this statement is to identify safety features and precautionary procedures to be followed by personnel using Battery BA-5590/U. DESCRIPTION The BA-5590/U primary battery is a high-energy power source that contains lithium metal, sulfur dioxide, a

32、nd organic solvents under pressure (30-60 psia at 700F) in hermetically sealed stainless steel cells. The contents are potentially flammable and/or noxious. Dimensions are 4.40 x 2.45 x 5.00 inches. Weight is 2.5 pounds. SAFETY FEATURES The BA-5590/U battery can be electrically arranged to provide 1

33、2 or 24 volts. This dual voltage capability is achieved through the use of a specially designed connector which makes the proper voltage connection upon mating with the equipment. The battery is protected by a 3.2 ampere slow blow replaceable fuse in each 12 volt section to protect against excessive

34、 currents or external short circuits which could lead to overheating, cell venting, or rupture. This fuse should not be bypassed or replaced with a higher rated fuse. Each cell (ten per BA-5590/U) is designed with a venting device which releases internal cell pressure to ambient pressure if the inte

35、rnal pressure exceeds 350-450 psia. Venting will occur when pressures become excessive due to cells which have overheated (200-2200F) and serves to prevent the cell from rupturing. If a cell vents, sulfur dioxide gas will be released, which is a noxious eye and respiratory irritant. Irritation will

36、occur long before toxic concentrations are reached and serves as an indication of its (SO2) presence. This battery contains no radioactive material. WARNING DO NOT USE unauthorized batteries or damaged batteries, and dispose of any batteries showing signs of damage. WARNING DO NOT USE lithium batter

37、ies in parallel circuitry unless the batteries or equipment are diode protected. G TM 11-5820-919-12 PRECAUTIONS Storage: Bulk storage of BA-5590/U batteries should be in a well ventilated, cool temperature facility. Refrigeration is not required. Battery life decreases with storage time and with in

38、creasing temperature. For this reason temperatures above 1300F should be avoided if possible. Handling: The BA-5590/U battery contains pressurized cells similar to aerosol cans. Therefore, under no circumstances should the battery be deliberately opened, crushed, punctured, disassembled or otherwise

39、 mutilated. Rupture of the cell could occur. The BA-5590/U battery should not be heated or incinerated, as overheating may produce internal pressure at a rate in excess of the venting capacity and could result in a cell or battery rupturing. Under no condition should the batteries be recharged. Such

40、 action could lead to venting, rupturing, or rupturing with fire. Transportation: Shipment of the BA-5590/U battery is regulated by the Department of Transportation in their Exemption 7052 and by the Department of the Army in TM 38-250. CAUTION Disposal: Batteries are considered hazardous waste. Con

41、tact local property disposal officer for disposal instructions. Overheating: In the unlikely event that an equipment operator detects the battery compartment becoming unduly hot, hears cells venting (hissing sound) or smells the irritating sulfur dioxide, he should immediately do the following: 1. T

42、urn off equipment. 2. Remove equipment or leave immediate area of equipment and do not approach for 12 hours. 3. Carefully remove the battery from the equipment and place away from area of operation, after 12 hours. Fire: In the event there are fires in which lithium batteries are involved, they are

43、 generally extinguishable with water in sufficient amounts so as to flood the burning materials. This will not only tend to cut off air access to the fire, but will cool down the batteries and surrounding combustibles so that cell venting and burning are minimized. If many cells have ruptured, lithi

44、um metal may be exposed. Burning lithium metal may respond satisfactorily to treatment with water. However, if not, efforts should be aimed at preventing the spread of the fire to other combustibles while letting the lithium metal burn itself out. Carbon dioxide extinguishers will not extinguish bur

45、ning lithium metal but will extinguish other combustible materials within or near the battery. H TM 11-5820-919-12 Voltage Delay: If there is a delay in the operation of the equipment that exceeds two minutes, the battery should be replaced. Remove the battery when the equipment does not operate pro

46、perly and replace with a new battery. Battery Removal: When equipment will not be used within 30 days, the battery should be removed from the equipment.
