4.4 - CHARGING PARAMETERS
Mostchargerscomepre-setfromthefactory.Ifyourchargerispre-programmed,
usetheinformationbelowtocheckifthesettingsarecompatiblewithAGM
batteries.Ifyouhaveaprogrammablechargerorinverter,usethefollowing
information for settings.
4.4.1 - CURRENT
Therecommendedbulkcurrentis20%ofthe20Hr.AHcapacityor0.20xC20
(20 Hr. capacity in AH).
Example:
DC115-12 is rated at 115AH @ 20 Hrs.
The recommended bulk current is 0.20 x 115 = 23 Amps
Themaximumallowablebulkcurrentis35%ofthe20Hr.AHcapacityor0.35xC20
(20Hr.capacityinAH),unlessotherwisestated.
Example:
DC115-12 is rated at 115AH @ 20 Hrs.
The recommended bulk current is 0.35 x 115 = 40 Amps
4.4.2 - VOLTAGE SETTINGS
4.4.3 - TEMPERATURE SETTINGS
If you have a programmable charger or inverter that has a temperature
compensationsetting,itshouldbesetto-4mV/°C/cellor-2mV/°F/cell.TABLE
