Frequently Asked Questions (FAQ)
Q1: How long does it take to fully charge the included 4000mWh AA batteries?
A1: Based on the charger's 350mA per-slot output and the standard charging formula (Capacity × 1.25 ÷ Current), it takes approximately 3 hours to fully charge a 4000mWh AA battery.
Q2: What is the advantage of the 4A high discharge current?
A2: The 4A continuous discharge current (6.5A peak) allows this battery to power high-drain devices such as camera flashes, wireless microphones, and high-performance RC cars. It delivers instant, powerful energy without the voltage drop or lag experienced with standard batteries.
Q3: What is the "Intelligent Battery Repair" function?
A3: When a battery has been over-discharged (left at 0% charge for a long time), the charging case can intelligently detect this and apply a safe micro-current to reactivate and repair the battery, effectively restoring it to a healthy charging state.
Q4: What safety features does this battery have?
A4: This battery is protected by a patented explosion-proof technology (Patent No. CN202411913698.6). It includes a full range of protections including over-current, over-voltage, over-charge, over-discharge, short-circuit, and over-temperature safeguards, ensuring safe and reliable operation.
Q5: How durable is the charging case's magnetic closure?
A5: The strong magnetic closure has been rigorously tested to withstand 5000 open/close cycles. Even when fully loaded with batteries and held upside down, the lid stays securely closed, ensuring your batteries are always protected.
