QUESTION
Does the OPTIMA Deep Cycle have a "memory"?
ANSWER
Lead-acid batteries do not suffer from memory effect. Many people think they have a memory because they experience a reduction in capacity or run-time as the battery ages. The active paste material in a lead-acid battery is a consumable item, similar to tread on a tire. Every time you cycle the battery some of the paste is used up. As the battery ages, less of the active paste is available to charge and discharge, resulting in a reduced operating time. This situation can be more apparent in the case where a high power or starting, lighting and ignition (SLI) battery is used in a deep cycle application. The plates of an SLI battery are designed for high current, short duration discharges. Plates in deep cycle batteries are better suited to repetitive deep-discharge applications.
