Product Number: 12FS31
Variations
Deep-cycle and standby applications demand a battery that sustains consistent output across prolonged discharge cycles without premature capacity loss. The Rolls 12FS31 is a 12V 130Ah lead-acid battery from the FS Series, engineered for commercial and industrial applications where dependable energy delivery is non-negotiable.
Rolls Battery Engineering has re-engineered the plate architecture at the core of the FS Series. Each cell incorporates a larger active surface area combined with higher-density paste, increasing both energy throughput and cycle resilience. This plate design directly addresses the elevated demands placed on batteries in modern commercial environments, where partial-state-of-charge operation and irregular recharge intervals are commonplace.
The 12FS31 measures 330mm 171mm 241mm (LWH) and carries a rated capacity of 130Ah at the C20 rate, with a 98Ah capacity at the C5 rate. Weight is 29.5kg. Terminal configuration and polarity should be verified against the product label prior to installation. Cross-reference codes for this unit include 12-LC-31, US31DCXC, and 30XHS. Start-stop compatibility is not confirmed; refer to the product label.
This product is available in two related variants within the FS Series HC range: the 12FSGC-HC (PID000199553) and the 12FS185-HC (PID000199554), offering alternative capacities for differing system requirements." The Rolls 12FS31 is supplied with a 1-year warranty covering defects in materials and workmanship under normal operating conditions. "Standard delivery: 13 working days within UK mainland. 30-day returns.
