Q1: How do I choose between the LR 3000mAh, LR 2000mAh, and Ni-MH 2600mAh?
A: 1. All three options are designed for low to moderate power consumption devices.
2. If you need to monitor battery levels easily and replace batteries frequently, we recommend the LR 2000mAh or LR 3000mAh:
- For a more budget-friendly option with decent capacity, choose the LR 2000mAh.
- For longer battery life and less frequent replacements, choose the LR 3000mAh.
3. If cost-effectiveness is a priority and you rarely replace batteries, the Ni-MH 2600mAh is a suitable choice.
Q2: Can the LR 2000mAh be charged with any data cable?
A: Yes, the LR 2000mAh can be charged using both A-C and C-C data cables.
Q3: What adapters are compatible with charging the LR 2000mAh? Does the battery have over-voltage protection?
A: 1. Compatible adapters include PD and QC adapters with 5V output, as well as standard 5V (≥2A) adapters. When using a multi-port data cable (e.g., 4-in-1), you can charge up to 4 batteries simultaneously.
- For a 5V/1A adapter, we recommend charging no more than 2 batteries at once.
- Charging 3 batteries may not be reliable, and charging 4 batteries will not work.
Note: This is due to variations in individual battery charging currents (0.35A ± 0.05A) and potential overrating of adapter output currents.
2. The battery does not have input over-voltage protection. Input voltage must not exceed 5.5V, as higher voltages may damage the battery. For safe charging, ensure the adapter output is 5V.
Q4: Why does charging the LR 2000mAh take the same time whether using direct USB-C charging or a charger?
A: The built-in integrated chip (for charging, discharging, and protection) is set to a fixed current of 350mA. As a result, charging time remains consistent regardless of whether you use direct USB-C charging or a charger.
