English · machine-assisted draft

A charger that regulates its output to maintain a selected charging current during that operating stage. This differs from holding voltage constant. Gerry’s 1995 FAQ uses the term for automotive lead-acid charging; its historical settings are not a charging program for every modern camper battery.

English · machine-assisted draft

An instrument that measures a liquid’s specific gravity. In Gerry’s battery FAQ it is used with electrolyte from accessible cells of a flooded lead-acid battery, helping compare cells and estimate charge. It does not measure voltage and is not a general-purpose tester for sealed or lithium camper batteries.

English · machine-assisted draft

A lead-acid battery rating expressed in minutes under a specified discharge test. Gerry’s FAQ describes a 25-amp load at 80 °F until a 12-volt battery reaches 10.5 volts. It is neither amp-hours nor a prediction of camper runtime, which depends on actual loads, conditions and discharge limits.

Cold Cranking Amps. a bogus number printed on the sides of automobile batteries to confuse the buyers. generally, the bigger this number is, the easier the battery will crank your car when everything is frozen. assuming everything is in perfect operating condition, of course.
