## Questions & Answers

**Q: Will this solar charger revive a completely dead car battery?**
A: Designed for 12V trickle charging/maintenance, it prevents discharge but can't revive sulfation-damaged batteries from long-term drainage. Optimal use requires 6V+ residual voltage.

**Q: How to confirm if it works with my vehicle?**
A: Compatible with all 12V lead-acid/AGM/LiFePO4 batteries (cars/boats/RVs). Our 30W upgraded model handles larger batteries up to 150Ah. Just connect via SAE port - zero wiring expertise required.

**Q: Does it drain power when not in sunlight?**
A: The zero-night-drain controller terminates charging at sunset and activates reverse current blockade. Energy loss is 85% lower than basic models according to lab tests.

**Q: What makes your charger safer than cheap alternatives?**
A: Features include ✓ ETFE-coated monocrystalline cells (IP67 waterproof) ✓ Triple-protection IC: Overcharge/Short-circuit/Reverse polarity ✓ CPB impact-resistant base (tested for 50km/h debris collisions)

**Q: How long to charge a standard SUV battery?**
A: ▸ 30W model: Fully charges 80Ah battery in ~5 days (2-4% daily trickle) ▸ For faster charging, pair with our 45W PRO Series (ideal for RVs/campers)
