It supplies 2 amps of controlled current for batteries between 2Ah and 20Ah and supports common lead-acid types (AGM, GEL, EFB, VRLA). The unit is not compatible with 24V systems or LiFePO4 chemistry and requires a mains outlet to operate.\u003c\/p\u003e\n\n\u003ch3\u003eHow does this charger protect batteries during charging?\u003c\/h3\u003e\n\u003cp\u003eThe AIYONFEI charger uses multiple built-in safeguards to prevent common charging hazards. Reverse polarity detection, overcharge and short-circuit protection, plus automatic stop and trickle modes all work together to protect both battery and charger from damage.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eReverse polarity detection to avoid accidental connection errors\u003c\/li\u003e\n  \u003cli\u003eOvercharge and overvoltage protections with automatic cutoff\u003c\/li\u003e\n  \u003cli\u003eShort-circuit protection and fireproof ABS housing for safe use\u003c\/li\u003e\n  \u003cli\u003eCooling design to dissipate heat during extended operation\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eCan it maintain a battery during long periods of inactivity?\u003c\/h3\u003e\n\u003cp\u003eYes — after a standard charge, the charger automatically switches to a trickle\/maintenance mode to hold battery voltage around 13.6V.

It fits riders, hobbyists, boaters and homeowners who store seasonal machines or want a compact, safe charger for everyday battery care. Avoid this unit if you use 24V systems or LiFePO4 batteries — for those, select an appropriate charger designed for the different voltage and chemistry requirements.\u003c\/p\u003e\n\u003csection class=\"product-faq-snippet\"\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Is this charger compatible with LiFePO4 batteries?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: No. The AIYONFEI 2A charger supports only 6V and 12V lead-acid types (AGM, GEL, EFB, VRLA), not LiFePO4.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: What battery sizes work best with this 2A charger?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: It’s optimized for 6V\/12V batteries from about 2Ah up to 20Ah for efficient charging and maintenance.\u003c\/p\u003e\n\u003c\/div\u003e\u003c\/section\u003e","brand":"AIYONFEI","offers":[{"title":"Default Title","offer_id":48085233664158,"sku":"B0GRT6KM1H","price":34.98,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0781\/2041\/9486\/files\/aiyonfei-front-view-charger_7b35c593-219c-4df5-a3b8-5dd64d19bcc0.jpg?v=1785868164","url":"https:\/\/northtrailauto.ca\/products\/aiyonfei-2a-smart-trickle-battery-charger-for-6v-12v-batteries-black-desulfation-maintenance-mode","provider":"North Trail Auto","version":"1.0","type":"link"}
