A built-in boost-charging mode actively revives weak or deeply discharged batteries, bringing them back to an optimal recharging level and extending overall battery lifespan — saving you the cost of premature replacements. The charger also functions as a clean, stable DC power supply for accessories that require regulated DC voltage.\u003c\/p\u003e\u003cp\u003eDesigned for caravan, camper trailer, 4WD and off-grid setups, the BT40AC is the single charger you need for an entire fleet of battery types. A front-panel selector lets you switch between SLA, GEL, AGM, Flooded, Calcium and LiFePO4 chemistries in seconds, making it equally at home in a workshop topping up a house bank or in the driveway conditioning a starter battery before a long trip. Its compact 194 × 127 × 45 mm footprint fits neatly into tight storage spaces, while the 40-amp output means even large-capacity battery banks are brought to full charge quickly.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eMulti-stage charging algorithm for faster, more thorough charges with no voltage-drop issues\u003c\/li\u003e\n\u003cli\u003eBoost-charging mode revives and revitalises weak or flat batteries\u003c\/li\u003e\n\u003cli\u003eSwitch-mode technology for high efficiency and compact size\u003c\/li\u003e\n\u003cli\u003eBuilt-in chemistry selector: SLA, GEL, AGM, Flooded, Calcium and LiFePO4 compatible\u003c\/li\u003e\n\u003cli\u003e40-amp output suits large house banks and high-capacity battery setups\u003c\/li\u003e\n\u003cli\u003eDoubles as a clean, stable DC power supply for sensitive accessories\u003c\/li\u003e\n\u003cli\u003eCompact 194 × 127 × 45 mm form factor for easy installation in tight spaces\u003c\/li\u003e\n\u003cli\u003eExtends battery lifespan by ensuring complete, properly staged charge cycles\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Baintech","offers":[{"title":"Default Title","offer_id":57364726415526,"sku":"BT40AC","price":383.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0466\/4688\/6566\/files\/12.png?v=1789269476","url":"https:\/\/campingaustralia.com.au\/products\/baintech-40a-ac-multi-stage-smart-battery-charger","provider":"Camping Australia","version":"1.0","type":"link"}
