FAQs

From consumption: list the loads, their draw in amps and their daily hours — that's the amp-hours used per day — then size capacity so daily use sits well inside it, since shallow cycling multiplies battery life. The honest sums via Ask Simon beat guessing; chronic undersizing is the category's most common mistake.

AGM for vehicles and boats: sealed, any-orientation, vibration-tolerant, maintenance-free. Flooded remains the budget workhorse where ventilation and orientation allow. Lithium rewrites the maths — more usable capacity, far more cycles, half the weight — where the duty is daily and the budget reaches; it expects matched charging, which the Victron equipment alongside provides.

Best practice says no: banks work hardest through their weakest member, and mixing ages, capacities or chemistries drags the new units down to the old one's behaviour. Replace banks as banks, keep cabling symmetrical, and monitor — the battery monitoring equipment in the section turns guesswork into numbers.

A compromise built honestly: enough cranking ability to start the engine, enough cycle tolerance to run house loads, for boats that want one battery doing both. Dedicated systems — a starting battery plus a deep-cycle house bank — outperform it where space allows, and the split is the standard recommendation as systems grow.

Returns are accepted within 30 days of purchase, in original packaging, on orders delivered within the United Kingdom. For damaged-on-arrival items, report within 24 hours with photographs to [email protected] — we will typically arrange collection and replacement at no cost to you. For parts that don't fit your machine, the Fit Guarantee covers a hassle-free return at no cost. For buyer's remorse — you've changed your mind or ordered the wrong item, email us first to obtain a Return Merchandise Number; a restocking fee may apply. Refunds are issued to the original payment method once the return is inspected.

Delivery time depends on the product, your destination, and availability — the estimated time for any item appears on the product page, and 'Check where we deliver' confirms coverage for your postcode before you order.

Leisure, Marine, Industrial & Renewable Batteries

FilterFilters
View as Grid List

Leisure, marine, industrial and renewable batteries cover the deep-cycle side of the section: the batteries bought for stored energy rather than cranking punch, powering caravans and motorhomes, boats, off-grid systems and the industrial equipment that draws steadily rather than in bursts. PartsForMachines supplies the range as an Authorised Distributor and Seller for Yuasa and Victron Energy, with the wider ranges alongside.

The duty defines the buying logic: deep-cycle batteries are specified by usable capacity, how many amp-hours the loads draw between charges, by chemistry, and by cycle life at working depth of discharge, the honesty figure that separates leisure tiers. Flooded and AGM lead-acid cover the traditional leisure and marine duties, with AGM's sealed, any-orientation, vibration-tolerant build suiting boats and vehicles, while lithium options change the arithmetic where weight, usable capacity and cycle count justify the price, the Victron ranges leading that territory alongside the charging and monitoring equipment that lithium systems expect. Marine adds its own demands, vibration and dual-purpose starting-plus-house duties, and renewable installations size banks around daily harvest and autonomy. Each product page lists capacity, chemistry, cycle data and dimensions, with Compare lining up options and Ask Simon answering sizing questions against the loads described.

System honesty rules the category: capacity sized to real consumption, charging matched to chemistry, and batteries in banks matched in age and type.

Solar panels and charging sit alongside in the same section. For system-level advice, contact the team via WhatsApp 07754288583.
