- Lithium-ion: 26650, 21700, 18650, 14500, 18350, 17500
- Nickel-Metal Hydride (NiMH): AA, AAA, C
- Nickel-Cadmium (NiCD): AA, AAA, C It automatically detects battery type and applies appropriate charging parameters.
Q: Can I charge different battery types simultaneously? A: Yes! Each of the 4 channels operates independently, so you can charge different battery sizes and types at the same time.
Q: Will it work with batteries from local Bangladesh brands? A: Yes, it works with any standard rechargeable battery regardless of brand, as long as it matches the supported sizes (AA, AAA, 18650, etc.).
Q: Can I use it to charge non-rechargeable alkaline batteries? A: No, never attempt to charge alkaline or other non-rechargeable batteries. The charger may detect and reject them, but forcing it could cause leakage or damage.
Charging Process & Modes
Q: How do I select the right charging current? A:
- 300-500mA: Gentle charging for better battery lifespan
- 700-1000mA: Faster charging when you need batteries quickly
- Higher currents (700-1000mA): Only available on 2 channels simultaneously
Q: What does TEST mode actually do? A: TEST mode performs a complete discharge-charge cycle and measures actual battery capacity. This helps you:
- Identify weak or damaged batteries
- Compare battery performance
- Decide when batteries need replacement
Q: How long does charging typically take? A: Charging time depends on battery capacity and selected current:
- AA (2000mAh) at 500mA: ~4 hours
- 18650 (3000mAh) at 1000mA: ~3-4 hours
- AAA (800mAh) at 300mA: ~3 hours
Q: What is STORAGE mode and when should I use it? A: STORAGE mode charges lithium batteries to 3.7V (about 40% capacity), which is optimal for long-term storage. Use it when storing lithium batteries for months without use.
Safety & Troubleshooting
Q: What safety features does it have? A: Multiple protection systems:
- Reverse polarity detection
- Overcharge protection
- Short circuit protection
- Automatic error detection for damaged batteries
