2 Cranking Amps or CA represents the amount of power a new (fully charged) BATTERY can deliver for 30 seconds at 32 degrees Fahrenheit before the voltage falls to V (six cells). This rating can also be referred to as Marine Cranking Amps (MCA). Reserve Capacity or RC is a very important rating. This is the number of minutes a fully charged BATTERY at 80 F will discharge 25 amps until the BATTERY drops below volts. Amp hour or AH is a rating usually found on deep cycle batteries. If a BATTERY is rated at 100 amp hours it should deliver 5 amps for 20 hours, 20 amps for 5 hours, etc.

3 Japanese industrial standards or JIS is a BATTERY rating option on some conductance testers which will test a BATTERY to a Japanese BATTERY rating standard. Deutsches Institut f r Normung or DIN is a BATTERY rating option on some conductance testers which will test a BATTERY to a German BATTERY rating standard. Common BATTERY Terminology BATTERY MAINTENANCE management PROGRAM Conventional BATTERY Design NSN 6140-01- 446-9498 6 TMF/TYPEI (Dry with over-packed electrolyte) NSN 6140-01-446-9506 6 TMF/TYPEII (for consignment) BATTERY MAINTENANCE management PROGRAM (+) and (-) plates are connected to make a 2 volt cell.

4 All 6 cells are connected inside the box to make a 12 volt BATTERY The case is filled with electrolyte (sulfuric acid & water) Electrolyte must always cover the BATTERY plates (but don t fill to top). - + - + - + - + Conventional BATTERY Design BATTERY MAINTENANCE management PROGRAM 6TL, 6 TLFP, 6 TMF, and other commercially available batteries All of these batteries are flooded ( wet ) cell lead acid batteries. Though they appear similar they have different chemistry, capacities and voltages. Conventional style automotive batteries in use by the US Military: 6 TMF The current BATTERY provided by military supply.

5 Brown case with a black top. It is also a lead calcium plate chemistry. Built-in hydrometer (a green eye). Note: The green eye only allows you to look at one cell in the BATTERY and as such is not a reliable indication of overall BATTERY condition. That is why the eye can indicate a BATTERY is good but it still doesn t perform properly. Conventional BATTERY Design BATTERY MAINTENANCE management PROGRAM Conventional style generator batteries in use by the US Military: 4HN, 2HN Use lead antimony plates, many are still in the government system.

6 Vary in size and voltage. 2HN, 12 volt. Used in small generators, the 5kW 4HN BATTERY is a 24-volt BATTERY (cannot be recovered in current military BATTERY shops due to the lack of a 24-volt charger). Conventional BATTERY Design 6 TLFP Black top and lead calcium chemistry plates. Produced and shipped as a Dry BATTERY with an acid over-pack. > Must be filled by unit > Must be charged prior to installation / use > Acid Over-pack is a shipment hazard.

8 BATTERY MAINTENANCE management PROGRAM Advantages of AGM batteries: Longer life Less MAINTENANCE Safer No leaking acid Eliminates corrosion to terminals & BATTERY trays No holes in your clothes, or burning skin Reduced chance of BATTERY explosion BATTERY won t leak or spill even if tipped over or accidentally cracked. BATTERY will work temporarily after cracked open or taking a round Lower internal resistance Higher cranking power More usable reserve capacity Faster recharge AGM BATTERY Design BATTERY MAINTENANCE management PROGRAM Same basic design as conventional BATTERY , except: AGM batteries use an Absorbent Glass Mat to contain all the electrolyte.

9 The AGM holds all the electrolyte like a super sponge. Contains a one-way safety valve to prevent out-gassing & loss of liquid during normal operation. High purity lead (not recycled) plus a little tin. Plates are compressed into cell partition, which: -Prevents plate to plate movement & shorting -Prevents loss of active paste material -Increases vibration resistance 6 TAGM Hawker BATTERY does have the potential to freeze: -Fully charged = -94F or -70C -Fully Discharged = -4F or -20C -Extremely Over-discharged (>6 Vdc) = 14F or -10C AGM BATTERY Design BATTERY MAINTENANCE management PROGRAM A little voltage means a lot!

10 OCV Full charge OCV charged AGM state of charge versus OCV Only .7 volt difference Basic BATTERY Facts BATTERY MAINTENANCE management PROGRAM The key to any MAINTENANCE Program is a good Preventive MAINTENANCE (PM) and Service Program. Test and service the batteries in the platform in conjunction with other scheduled MAINTENANCE services. PMCS also includes checking and charging batteries prior to installation. It is very common to get new batteries that have been sitting idle for months prior to your receiving them. Start with a fully charged BATTERY to ensure the BATTERY s life.
