Each Rolls deep cycle battery is date stamped at the time of manufacture for internal quality control purposes, allowing Distributors, Dealers and Customers to easily identify the specific date of manufacture.
The date code on Rolls-flooded models may be found on the product label in HHDDMMYYYY format. A stamped code representing the manufacture batch & date may also be visible on the negative terminal of some models.
Rolls GEL and LFP models include heat-stamped code on the case.
Rolls Legacy Date codes and AGM date Codes are explained in this document.
