Deltran Solar Battery Tender Application

by on Aug.18, 2011, under Battery Tenders, Solar

Thought a discussion of some typical battery “Group Codes” would be helpful…

Common battery size codes, i.e.,”Group” sizes, are based upon the physical size and terminal placement – NOT a measure of battery capacity.

Some typical Battery Group codes are: U1, 24, 27, and 31

  Group U1    34-40 Amp hours 12 volts    (powersport, motorcycle, atv, jet ski, lawn equipment)

    Charge maintained with Deltran 5W Solar Charger – 270 mA

    Example solar application batteries of the U1 Group code:

    Deka/MK 8GU1-DEKA Gel, 12 volt 31.6 AH

    Concorde Sun Xtender PVX-340T Solar Battery VRLA-AGM Deep Cycle Battery 34 AH

  Group 24    70-85 Amp hours 12 volts

    Charge maintained with Deltran 10W Solar Charger – 540 mA

    Example solar application batteries of the Group 24 code:

    Deka/MK Battery 8G24 Gel RV Battery (Group 24 – 12V, 84 AH)

    Concorde Sun Xtender PVX-690T Solar Battery VRLA-AGM Deep Cycle 69 AH

  Group 27     85-105 Amp hours 12 volts    (automotive engine start batteries)

    Charge maintained with Deltran 10W Solar Charger – 540 mA

    Example solar application batteries of Group 27 code:

    Deka/MK Battery 8G27-DEKA Sealed Gel Battery, 12 volt 88 AH

    Concorde Sun Xtender PVX-1040T Solar Battery VRLA-AGM Deep Cycle 104 AH

  Group 31    95-125 Amp hours Deep Cycle and Marine batteries

    Charge maintained with Deltran 15W Solar Charger – 830 mA

    Example solar application batteries of Group 31 code:

    Deka/MK 8G31-DEKA Gel, 12 volt 97.6 AH

    Concorde Sun Xtender PVX-1080T Solar Battery VRLA-AGM Deep Cycle 108 AH
