Rechargeable Sealed Lead -Acid Battery <br />Seale�ec <br />eable <br />POLUER 0�0//�50/V/� <br />MODEL PS-12400 <br />12 Volt 40 0 Amp Hr' ° <br />n�F <br />pa,H¢r-Sonic Corporation <br />PS=1 2400 <br />Power -Sonic rechargeable batteries are lead - <br />lead dioxide systems. The dilute sulphuric acid <br />electrolyte is suspended and thus immobilized. <br />Should the battery be accidently overcharged <br />producing hydrogen and oxygen, special one- <br />way valves allow the gases to escape thus <br />avoiding excessive pressure build-up. Other- <br />wise, the battery is completely sealed and is, <br />therefore, maintenance -free and leak proof. <br />PS-12180 is air transport approved, and meets <br />all current requirements set forth by the C.A.B., <br />F.A.A., I.A.T.A. and D.O.T. <br />U.L. recognizes model PS-12180 under file num- <br />ber MH 14328. <br />U� <br />PERFORMANCE SPECIFICATIONS <br />NominalVoltage..................................................................................................................................................... 12 volts (6 cells in series) <br />Nominal Capacity <br />20 hour rate (2000mA to 10.50 volts).................................................................................................................................. 40 A.H. <br />10 hour rate (3700mA to 10.50 volts).................................................................................................................................. 37 A.H. <br />5 hour rate (6600mA to 10.20 volts).................................................................................................................................. 33 A.H. <br />1 hour rate (24A to 09.00 volts)................................................................................................................................... 24 A.H. <br />ApproximateWeight................................................................................................................................................... 30.5 pounds (13.8 kg) <br />Energy Density (20 hour rate)............................................................................................. 1.42 Watt-hours/cubic inch (86.9 Watt-hours/1) <br />Specific Energy (20 hour rate)................................................................................................ 15.7 Watt-hours/pound (34.8 Watt-hours/kg) <br />Internal Resistance (Fully Charged Battery).................................................................................................... 6 milliohms (approximately) <br />Maximum Discharge Current ( < 7 Min.).................................................................................................................................. 120 amperes <br />Maximum Short -Duration Discharge Current ( < 10 Sec.).................................................................................................... 400 amperes <br />Terminals....................................................................................................................................................................
