How Old Or New Are Your Deep-Cycle Batteries?

Used and refurbished battery-powered equipment are abundant and are often found at great prices. Although the vehicle may be in good working order, it’s important to determine how old the deep-cycle batteries are. In most cases, battery manufacturers stamp or etch a date code on the battery indicating the month, year, and location of manufacture.

U.S. Battery uses a stamped code on the terminals of its flooded lead-acid batteries. The top left letter stamped on the terminal correlates to the month it was manufactured (A-L refers to January to December). In this example, the letter “K” is the 11th month indicating the battery was manufactured in November. The number indicates the year 2014, and the bottom letter specifies the U.S. Battery plant where it was produced.
