But smart alternators vary voltage, so you MUST connect the charger's IGN (ACC) cable to the Vehicle Ignition Port for them to work properly. **Q: What types of battery does the charger support?** A: It's suitable for 12V Lithium, Gel, AGM, and Calcium batteries. This charger enables the batteries to reach a full 100% charge. Additionally, it has the capability to revive lithium batteries that have become discharged to a low voltage. **Q: How do l set the battery since there is no display screen?** A: To change the battery type, press and hold the SELECT button on the side of the battery charger. The LED lights corresponding to each battery type will illuminate in sequence, indicating the available options. **Q: If both solar power and the engine are available, can we prioritize using solar power to charge the battery?** A: Our product defaults to DC charging. To prioritize solar charging, simply press the SELECT button on the side. **Q: Can solar charging and DC charging be switched automatically?** A: Charging automatically switches to solar when 1. Generator ON: DC <11.3V & Solar >13V 2. Generator OFF: DC <12.7V & Solar >13V --- ## Why Shop on Desertcart? - ๐Ÿ›’ **Trusted by 1.3+ Million Shoppers** โ€” Serving international shoppers since 2016 - ๐ŸŒ **Shop Globally** โ€” Access 737+ million products across 21 categories - ๐Ÿ’ฐ **No Hidden Fees** โ€” All customs, duties, and taxes included in the price - ๐Ÿ”„ **15-Day Free Returns** โ€” Hassle-free returns (30 days for PRO members) - ๐Ÿ”’ **Secure Payments** โ€” Trusted payment options with buyer protection - โญ **TrustPilot Rated 4.5/5** โ€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.com.br/products/743490620-40a-dc-dc-mppt-battery-charger-12v-dual-input-solar](https://www.desertcart.com.br/products/743490620-40a-dc-dc-mppt-battery-charger-12v-dual-input-solar) --- *Product available on Desertcart Brazil* *Store origin: BR* *Last updated: 2026-09-07*
