Deep cycle applications demand a battery that can sustain repeated discharge and recharge cycles without premature capacity loss a challenge that standard SLI batteries are not designed to meet. The Rolls 6FSL16-HC is a 6-volt deep cycle battery from the FS Series, engineered specifically for stationary, traction, and renewable energy storage duties where long service life and consistent output are non-negotiable.
Rolls Battery Engineering has addressed the growing performance demands of modern energy applications by incorporating a redesigned plate architecture into the FS Series. The plates feature a larger active surface area combined with higher density paste formulation, delivering improved charge acceptance, reduced internal resistance, and greater energy throughput across the battery's service life. This construction reflects Rolls' established approach to flooded lead-acid technology, prioritised for reliability in demanding commercial environments.
The 6FSL16-HC measures 318mm (L) 181mm (W) 425mm (H inc. terminal) and carries a rated capacity of 425Ah at the C20 rate and 340Ah at the C5 rate, giving a clear picture of usable energy under both moderate and high-demand discharge profiles. Polarity configuration should be confirmed by consulting the product label directly. Cross-reference codes for this unit include 6-LC-L16-HC, USL16HC, and L16P, aiding identification against existing fleet or system records. Weight is 55.5kg.
The 6FSL16-HC is one of several FS Series 6-volt variants available from PartsForMachines, including the 6FSGC, 6FSGC-HC, 6FSGC-SC, 6FS145, 6FSGC-DIN, 6FS250-SC, 6FS305-HC, 6FS305-SC, and 6FSL16, allowing selection across a range of capacity and configuration requirements.
This battery is supplied with a 1-year warranty from Rolls Battery Engineering, covering manufacturing defects under normal operating conditions.
