Product Number: PMDC31
Variations
Powering a caravan, motorhome, or marine vessel through extended off-grid use demands a battery capable of repeated deep-discharge cycles without loss of capacity or reliability. The Powermax PMDC31 is a 12V 105Ah dual-purpose leisure battery engineered to meet that demand, combining respectable cold-cranking performance with sustained auxiliary power delivery in a single unit.
Manufactured to lead-acid STANDARD technology, the PMDC31 is produced by Powermax Battery, a brand purpose-built for leisure and auxiliary power applications. The construction is designed for dependable performance across caravan, motorhome, narrowboat, and marine installations where both engine-start and habitation loads must be served reliably.
The PMDC31 is housed in a Group 31 (GR31) case measuring 330mm × 172mm – 239mm (L × W × H) and weighs 23.26kg. It delivers a rated capacity of 105Ah (C20) and a Cold Cranking Amps figure of 680A (EN). The terminal type is DT (dual terminal), polarity is Standard (Polarity 1, positive on left), and the hold-down configuration is B00. No direct cross-reference codes are provided; compatibility with start-stop systems is not confirmed – refer to the product label before fitment.
The PMDC31 is part of a wider Powermax dual-purpose leisure range. Related variants include the PMDC24 (PID000222630), PMDC25 (PID000222631), and PMDC27 (PID000222632), offering alternative capacities to suit different power requirements.
This battery is backed by a 2-year manufacturer warranty, providing assurance of build quality and performance for the duration of typical leisure-use seasons.
Standard delivery: 1–3 working days within UK mainland. 30-day returns.
Choosing the correct leisure battery is all about understanding your power usage. The Powermax leisure range covers all situations, applications and levels of power usage depending on what you need from your battery. Leisure battery performance is measured in cycles; these cycles are what determine their NCC rating. Battery cycles refer to the number of discharge/recharge cycles the battery is capable of when discharged by up to 50% between recharging.
Key Feature:Suited for passenger vehicles, balancing reliable cold‑cranking performance with long service life for daily use.
