General Safety Guidelines for Rechargeable Batteries:

1. Charging Safety

Use the Right Charger:

Always use a charger designed for your battery type (e.g., Li-ion, NiMH, LiPo).

Mismatched chargers can cause overheating or explosions.

Avoid Overcharging:

Unplug batteries once fully charged. Many modern chargers have auto-shutoff, but monitor charging for older models.

Charge in a Safe Area:

Keep batteries away from flammable materials and charge on non-flammable surfaces (e.g., ceramic tiles).

2. Temperature Control

Avoid Extreme Temperatures:

Do not charge or use batteries in temperatures below **0°C (32°F)** or above **45°C (113°F)**.

High heat can cause leaks or fires; cold reduces efficiency.

Cool Down After Use:

Let batteries rest before recharging, especially after heavy use (e.g., drones, power tools).

3. Physical Handling

Prevent Damage:

Avoid puncturing, crushing, or bending batteries. Physical damage can lead to internal short circuits.

No Water Exposure:

Keep batteries dry. Water can corrode contacts or trigger chemical reactions.

4. Storage Recommendations

Partial Charge for Long Storage:

Store rechargeable batteries at **30–50% charge** to prevent capacity loss.

Full discharge or full charge during storage degrades performance.

Cool, Dry Location:

Ideal storage temperature is **10–25°C (50–77°F)**. Avoid humid environments.

5.Usage Precautions

Avoid Over-Discharging:

For Li-ion/LiPo batteries, never drain below **2.5–3.0V per cell**. Over-discharging can permanently damage cells.

Use Battery Management Systems (BMS):

For multi-cell packs (e.g., in laptops, EVs), ensure a BMS is installed to balance voltage and prevent over-discharge.

6.Transportation & Disposal

Protect Terminals:

Cover battery contacts with tape during transport to prevent short circuits.

Recycle Responsibly:

Never dispose of rechargeable batteries in regular trash. Use certified recycling centers.
