Detailed Answer
Ni-MH batteries are rechargeable, perform well in low temperatures (-20°C retains 80%+ capacity), and contain no heavy-metal pollution; they are common rechargeable batteries in AA/AAA sizes. The Leader LD series supports Ni-MH, suitable for outdoor low-temperature scenarios. Ni-MH has a memory effect (shallow charge/discharge requires periodic full charge/discharge calibration) and slightly higher self-discharge (~20% per month).
| Advantages | Good in cold / eco-friendly |
| Drawbacks | Higher self-discharge |
| Best for | Low-temperature scenarios |
Note:Fully charge Ni-MH batteries before storage to avoid self-discharge depletion.
