Quick Tips!

Generally, when fast (a.k.a., recovery) charging two 12-volt Hawker^® batteries that are wired in 24-volt series or series-parallel, an ideal charger should have an output voltage between 28.5 to 30.0 VDC. The optimal constant voltage is 28.8 VDC when the battery’s temperature is at 77^o F. Under normal conditions (when the battery’s temperature is at or above 68^o F), it’s not recommended to use a charger whose output voltage is less than 28.3 VDC or exceeds 30.0 VDC.

Answer to question from last issue:

I hear that Hawker^® batteries are AGM...what is that?

AGM is an acronym for Absorbed Glass Mat. It’s an absorbent fiberglass mesh material. Within an AGM battery, this fiberglass matting is layered between the negative (-) lead plates and positive (+) lead-dioxide plates. AGM serves two purposes: (1) it acts as a plate separator between the negative and positive plates…so they don’t touch and short out the battery, and (2) the matted material fully absorbs the electrolyte (allowing no free-flowing liquid), thereby making the battery essentially spill-proof. As a result of the tightly packed compression between the AGM material, the plates, and the cell walls of the battery…AGM batteries are the most vibration and impact resistant lead-acid batteries available today.

Did you know?

Pulse Hot Cranking Amps (PHCA) is a non-standard battery industry rating referring to a 5 second burst of cranking power that a fully-charged battery can provide to start an engine. The rating specifically refers to the amount of amps that a nominal 12-volt battery can deliver at 80^o F (27^oC) for 5 seconds while still maintaining a battery voltage of at least 7.2 volts. For example, the Hawker^® ARMASAFE™ Plus 6TAGM battery has a PHCA rating of 2250 amps!
