Smart charger — microprocessor-controlled, multi-stage charging that adjusts voltage and current to the battery's state. The trade default for daily workshop battery management. Rapid charger — high current output (typically 20-100A) for time-pressured fleet work where multiple batteries need fast turnaround. Hard on battery service life if used routinely. Trickle charger — low output (1-2A) for long-duration storage and battery maintenance. Cannot recharge a flat battery in reasonable time. For most workshop applications, a 10-20A smart charger covers daily charging without stressing the battery.

Cars and light vans — 600-800 peak amps (PA) covers most petrol and diesel engines up to ~3.0 litres, including cold-start conditions. Larger diesels, vans, and 4×4s — 1,000-1,200 PA. Commercial vehicles and tractors — 1,500-2,000 PA at 12V. Plant equipment and HGVs with 24V systems — 3,000+ PA combined 12V/24V output. The Sealey RoadStart range covers the spectrum from compact emergency packs through to commercial-grade dual-voltage units. Always size up rather than down — undersized boosters cycle rapidly, overheat, and may fail in cold conditions when starting amps are most needed.

Modern smart chargers — Sealey SpeedCharge/SmartCharge, SIP smart chargers, Draper smart range — explicitly support flooded, AGM, EFB, and gel chemistries through battery-type selection switches or automatic detection. Lithium-ion batteries require a dedicated lithium charger and must not be charged on a lead-acid charger — voltage profiles and termination behaviour are fundamentally different. Always check the charger specification supports your battery chemistry. Cheaper basic chargers without chemistry selection may damage AGM and EFB batteries through over-pressurisation or incorrect float voltage.

Yes — for fleet workshops, commercial vehicle workshops, and plant maintenance operations, larger rapid-charger installations and bulk charger bay arrangements are available across the Sealey, SIP, and Draper ranges. Multi-bay charger banks for charging 4-8 batteries simultaneously, dedicated 24V fleet chargers, and the larger SuperBoost and equivalent rapid units handle high-throughput applications. WhatsApp 07754288583 with the workshop's typical battery throughput (batteries per day, voltage mix, available electrical supply) for a configured-system quotation.

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 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. Next-day delivery is available on most products; the option appears at checkout when applicable. We deliver across the UK, Europe, the Middle East, and Africa. Use the country selector at checkout to confirm coverage and delivery options for your destination.

Chargers & Boosters

Within Power Tools Accessories, Chargers and Boosters covers the battery management equipment used in trade workshops, fleet maintenance bays, and mobile-service operations — battery chargers (trickle, smart, and rapid), jump-start booster packs, battery testers and analysers, and battery-care accessories. This is the highest-demand sub-category within Power Tools Accessories. Sub-categories include Battery Chargers (trickle through smart through rapid units, 12V and 24V applications, dual-voltage workshop chargers), Boosters (the jump-start packs ranging from emergency car packs through commercial-vehicle and plant boosters), Battery Testers and Analyser (load testers, smart battery analysers, and CCA testing equipment), Battery Care (desulphators and battery-conditioning equipment), and Portable Power Stations (lithium-based portable power for off-grid and remote-site applications). Parts For Machines is an Authorised Distributor and Seller of Sealey, SIP, and Draper across chargers and boosters. Sealey leads with the broadest range — the Sealey RoadStart series of jump-start booster packs is a trade standard for emergency vehicle starting; the Sealey SpeedCharge and SmartCharge ranges cover automatic multi-stage smart chargers; and the SuperBoost rapid chargers cover heavier fleet-workshop applications. SIP covers battery chargers and boosters across the trade-workshop range. Draper covers the entry-trade end of chargers and boosters. Battery chargers are sold by output current (typically 4A through 100A for trade applications), supported voltages (12V single, 24V single, 12/24V dual), supported chemistries (flooded, AGM, EFB, gel, lithium where applicable), and charging programme (manual, multi-stage automatic, microprocessor-controlled). Product pages list current, voltage, supported chemistries, and any specialist features (alternator support, glow-plug pre-heat function on diesel chargers). Boosters are sold by peak amps (PA), continuous amps, and supported voltage. Smaller emergency boosters at 600-800 PA cover cars and light vans; commercial and plant applications need 1,500-3,000 PA, often in 12V/24V dual-voltage configurations.
