ARMY TM 9-6115-604-12NAVY NAVFAC P-8-633-12(a)The electrolyte Is diluted sulfuric acid. Ensure vent holes In cell caps are open. Prepare 4.1 gallons (15.5 L)of electrolyte, MIL-STD-605, Class II, for each battery.(b)Using an acid-proof funnel, carefully pour the electrolyte into the battery cells. Cover the plates in each cell with 3/8 inch (9.5 m) of solution.(c)Install the battery in accordance with step (5) (e) through (h), below.(d)The electrolyte level must be rechecked and adjusted approximately 30 minutes after initial fill.(e)Bring battery electrolyte to proper specific gravity (1.250 or higher at 800F (270C)).NOTEBattery charger BC1 applies an equalizing charge to batteries BT1 through BT4 for up to 24 hours TheTIMER is set from 1 to 24 hours when the battery charger is used. Actual length and intensity of charge isdetermined by internal battery charger circuitry. The TIMER rotates toward zero hours as time elapses.The DC VOLTS meter and DC AM- PERES meter on the door of BC1 indicate battery charger outputvoltage and current at any given moment.(5)Replace See Figure 3-6(a)Remove the battery covers (1) by pivoting quarter-turn studs (2).(b)Disconnect the negative-cables, the positive cables, and the jumper cables from the storage batteries BT1 through BT4 (4) See battery connection nameplate (5) on battery cover for cable identification.(c)Remove the hexagonal nuts (6) and lockwashers (7) and remove the four battery hold-down channels (8). It is not necessary to remove the retaining battery studs (9).(d)Lift out the storage batteries BT1 through BT4 (4).(e)Install new batteries on the battery tray (10), orienting the terminals as shown on battery connection nameplate (5).(f)Install the battery hold-down channels (8) and secure with hexagonal nuts (6) and lockwashers (7).(g)Connect the cables as shown on battery connection nameplate (5).(h)Install the battery covers (1) with quarter-turn studs (2)bMaintenanceofBatteryCables.There are six battery cables two positive leads, two negative leads, and two jumpercables Connectors may be lugs (1, Figure 3-7) or clamps (2) The jumper cables have two clamp battery terminals. A redsleeve (3) identifies positive terminal ends Negative terminal ends are identified with a black sleeve (4).(1)Inspect Remove battery covers by turning quarter-turn studs (2, Figure 3-6) and visually Inspect cables and connectors for corrosion and looseness.(2)Test.(a)Unfasten attachments and separate all of the negative terminal ends.(b)Separate all positive terminal ends and lift out the battery cables(c)Using a multimeter (ohms), test continuity of each cable Meter (RX1) should read zero.3-27
