This HULK 4X4 7.5A switchmode battery charger handles both voltages in the one unit, running an 8-stage automatic charge and maintenance cycle so batteries stay topped up without you standing over them.\u003c\/p\u003e\n\u003cp\u003eIt's built to work across the batteries you're actually likely to own: wet cell, GEL, AGM, MF, calcium and EFB lead-acid, plus 12V lithium rechargeable batteries. The XB2 smart processor reads the battery, works out what stage of charge it needs, and steps through the cycle automatically, including a boost function for batteries that have dropped low. Even a genuinely flat battery isn't necessarily a write-off: the charger can rescue batteries down to 2V on a 12V system or 16V on a 24V system before starting the main charge.\u003c\/p\u003e\n\u003cp\u003eConnection is straightforward, with interchangeable battery clamps and eyelet terminals that plug straight into the charger lead, so you can leave permanent terminals fitted to a vehicle or boat and just clip the lead on when needed. There's also a dedicated power supply mode (5A at 13.6V) if you need a stable 12V feed rather than a charge cycle. The IP65-rated case and 2-year warranty round it out as something built to live in a shed or tool box rather than a display cabinet.\u003c\/p\u003e\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e8-stage fully automatic charge and maintenance cycle, so there's no risk of overcharging even left connected long-term.\u003c\/li\u003e\n\u003cli\u003eWide battery compatibility: Wet, GEL, AGM, MF, Calcium and EFB lead-acid batteries, plus 12V lithium rechargeable batteries.\u003c\/li\u003e\n\u003cli\u003eMaintains batteries from 18Ah up to 240Ah.\u003c\/li\u003e\n\u003cli\u003eXB2 smart processor automatically diagnoses, recovers, charges and maintains the battery through the cycle.\u003c\/li\u003e\n\u003cli\u003eBattery rescue function for drained batteries, down to 2V on 12V systems and 16V on 24V systems.\u003c\/li\u003e\n\u003cli\u003eDedicated power supply mode delivering a steady 5A at 13.6V.\u003c\/li\u003e\n\u003cli\u003eConstant current charging with boost and memory functions, plus spark-proof, short circuit and reverse polarity protection.\u003c\/li\u003e\n\u003cli\u003eInterchangeable battery clamps and eyelet terminals that plug straight into the charger lead.\u003c\/li\u003e\n\u003cli\u003eIP65-rated housing and a 2 year warranty.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003ctable\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eCharger type\u003c\/td\u003e\n\u003ctd\u003eSwitchmode, 8-stage fully automatic\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOutput\u003c\/td\u003e\n\u003ctd\u003e12\/24V, 7.5A\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower supply mode\u003c\/td\u003e\n\u003ctd\u003e5A at 13.6V\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBattery rescue threshold\u003c\/td\u003e\n\u003ctd\u003eAbove 2V (12V systems), above 16V (24V systems)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBattery capacity range\u003c\/td\u003e\n\u003ctd\u003e18Ah to 240Ah\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCompatible battery types\u003c\/td\u003e\n\u003ctd\u003eWet, GEL, AGM, MF, Calcium, EFB lead-acid; 12V lithium rechargeable\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProtection\u003c\/td\u003e\n\u003ctd\u003eSpark proof, short circuit protected, reverse polarity protected\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProtection rating\u003c\/td\u003e\n\u003ctd\u003eIP65\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimensions\u003c\/td\u003e\n\u003ctd\u003e220mm x 92mm x 60mm (L x W x H)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWarranty\u003c\/td\u003e\n\u003ctd\u003e2 years\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch3\u003eWhat's Included\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eInterchangeable battery clamps\u003c\/li\u003e\n\u003cli\u003eEyelet terminals (direct plug-in to charger lead)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eApplications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eIdeal battery charger to set and forget for Motor Vehicles, SUV, Golf Carts, Boats, ATV, Tractors, RV, Trucks etc\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cdiv data-faq=\"product\"\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n  \u003cdetails\u003e\n    \u003csummary\u003eDoes this charger switch automatically between 12V and 24V, or do I need to select it manually?\u003c\/summary\u003e\n    \u003cp\u003eIt's rated for both 12V and 24V systems, with the XB2 smart processor diagnosing the battery and applying the appropriate charge profile as part of its automatic cycle.

This HULK 4X4 unit uses that switchmode design to run its 8-stage automatic charge cycle across the 12V and 24V battery types it supports.\u003c\/p\u003e\n  \u003c\/details\u003e\n\u003c\/div\u003e","brand":"Hulk 4x4","offers":[{"title":"Default","offer_id":48657173348577,"sku":"HU6554","price":139.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1926\/8595\/files\/hulk-4x4-automatic-switchmode-battery-charger-7-5a-12-24v-8-stage-921.webp?v=1784083343","url":"https:\/\/www.4x4downunder.com.au\/products\/hulk-4x4-automatic-switchmode-battery-charger-7-5a-12-24v-8-stage","provider":"4x4 Down Under","version":"1.0","type":"link"}
