Frequently Asked Questions
Q: What types of batteries are compatible with this 4-slot smart charger?
A: This charger is designed exclusively for 1.5V constant voltage lithium-ion (Li-Ion) rechargeable batteries in AA (size 5) and AAA (size 7) formats. It is not compatible with standard alkaline, NiMH, NiCd, or non-lithium rechargeable batteries — always verify your battery type before charging.
Q: How do I know when my batteries are fully charged?
A: Each slot has a dedicated LED indicator. The LED signals the current charging status — when charging is complete, the indicator changes state so you know at a glance that your batteries are ready to use.
Q: Can I charge fewer than 4 batteries at once?
A: Yes! Each of the 4 slots operates independently. You can charge 1, 2, 3, or all 4 batteries at the same time in any combination of AA and AAA sizes without any issue.
Q: What cable do I need to power this charger?
A: The charger accepts both Micro USB and Type-C cables with a DC 5V/1A input — the same cables used for many smartphones and other common devices. A charging cable is required but may not be included; please check your package contents.
