For standard car batteries (40-80 Ah), 4A is just right - safe and efficient charging.\u003c\/p\u003e\n\u003cp\u003eFor larger batteries (100 Ah+) 4A will still work, but charging will be very slow.\u003c\/p\u003e\n\u003cp\u003eIn short: Look at the battery capacity (Ah). Choose a charger with about 10% of the battery's capacity as charging current. The safe maximum for most lead-acid batteries is approx. 20% of the Ah rating. A charger that is too small will result in a very long charging time, while a charger that is too large can damage the battery.\u003c\/p\u003e\n\u003cp\u003eInstructions or tips: Make sure there is good ventilation around the battery during charging. Check that the battery terminals are clean to ensure optimal contact, and that the clips are attached correctly before connecting power. The charger is suitable for maintenance charging during winter storage of boats and leisure vehicles.\u003c\/p\u003e","brand":"1852","offers":[{"title":"Default Title","offer_id":55921083351371,"sku":"1251005","price":25.95,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0878\/9183\/7259\/files\/1251005_XL.jpg?v=1763370075","url":"https:\/\/www.boatlab.net\/products\/1852-vedligeholdelseslader-4a-6-12v-auto","provider":"BoatLab","version":"1.0","type":"link"}
