Frequently Asked Questions (FAQ)
Q1: How long does it take to fully charge the included batteries?
A1: Based on the standard charging formula (Capacity × 1.25 ÷ Current), a 3404mWh AA battery takes approximately 1.5 hours (at 500mA), and an 1184mWh AAA battery takes approximately 1.5 hours (at 400mA).
Q2: Can I charge AA and AAA batteries at the same time in this charger?
A2: Yes. The DLP-533 features 4 independent slots. You can safely place the 2 AA batteries in some slots and the 2 AAA batteries in other slots to charge them simultaneously without interference.
Q3: What do the green LED indicators mean on this charger?
A3: The green LED light stays illuminated while the battery is actively charging. Once the battery reaches full capacity, the charger automatically stops and the LED turns off or changes state, indicating it is ready for use.
Q4: Why does this charger use a 4.20V cut-off voltage for 1.5V lithium batteries?
A4: Although these batteries are labeled 1.5V, 1.5V AA/AAA lithium batteries reach full saturation at 4.2V. The DLP-533 uses a precise 4.20V±0.05V cut-off to fully charge these cells safely and optimally.
Q5: What is the advantage of this mixed-size combo kit over a single-size kit?
A5: This combo kit offers ultimate versatility. It equips you to power a wide range of household devices—from high-drain AA-powered smart locks and KTV microphones to compact AAA-powered remote controls and sensors—all managed by a single, fast-charging smart charger.
