Usage Guide for EBL Batteries

To learn some suggestions and cautions when using EBL batteries. Learn how to use, store and dispose of them properly.



  1. Rechargeable batteries should be fully charged before initial use or after prolonged storage.
  2. Follow the user manual for recommended charging methods.


  1. Store batteries in a cool, dry place.
  2. Avoid using batteries in enclosed compartments to prevent hydrogen gas buildup.
  3. Ensure proper ventilation in battery compartments to prevent potential explosions.
  4. When storing or transporting, please fix the battery separately to prevent external short circuit.

  1. Charge and discharge batteries every 3 months during long-term storage.
  2. Use the appropriate charger for your battery type (Li-ion, Ni-Cd, Ni-MH).
  3. Ensure correct placement of positive and negative terminals when connecting to the charger.
  4. Turn off devices if battery power drops to avoid over-discharging.
  5. Disconnect batteries from devices when not in use.
  6. Hold the connector, not the cord, when disconnecting the battery.

Safety Measures:

  1. Cool down overheated batteries in a well-ventilated area before charging.
  2. Keep batteries away from children, and seek medical attention if swallowed.
  3. Recycle all rechargeable batteries; do not dispose of them.

Charging and Discharging:

  1. Do not reverse charge batteries.
  2. Avoid mixing new and semi-used batteries to prevent over-discharge.

Physical Handling: 

  1. Do not short-circuit batteries; it may cause permanent damage.
  2. Do not solder directly on the battery.
  3. Do not subject batteries to extreme temperatures, overcharging, or overdischarging.
  4. Do not mix EBL batteries with other brands or different chemistries.

Safety Precautions:

  1. If batteries exhibit noise, high temperature, or leakage, stop using them.
  2. Do not touch or handle hot batteries until they cool down.
  3. Do not remove the outer sleeve or cut into the battery housing.
  4. Never put batteries into water or seawater.
  5. Do not disassemble or subject batteries to pressure or shock; it may cause heat generation or fire.

Additional Relevant Questions

There are various reasons why a battery may not charge:

  1. Aging: Over time, batteries naturally age, leading to reduced capacity and diminished charging capability. Aged batteries may struggle to hold a charge or reach the expected charge level.
  2. Damage: Physical damage or overcharging during use can lead to battery damage, rendering it unable to charge.
  3. Internal Faults: Internal component failures or short circuits within the battery may hinder charging. This could be due to manufacturing defects or other issues.
  4. Non-rechargeable Battery: Attempting to charge a non-rechargeable battery can result in failure and potential damage. Ensure the battery is designed for recharging.
  5. Charger Issues: Using an incompatible or damaged charger can prevent the battery from charging. Charger malfunctions or connection problems may also affect charging effectiveness.
  6. Battery Protection: Some batteries have built-in protection mechanisms that halt charging when issues arise to prevent safety hazards.

It is advisable to recharge the battery every 3 months if it has been fully charged and remains unused for an extended period. This helps maintain its health and prevents performance degradation.

The recommendation depends on the specific circumstances. Generally, it's advisable to rotate the use of batteries, meaning to alternate between different batteries to ensure they all receive adequate charging and usage. This helps balance the lifespan and performance of the batteries.
On the other hand, if a device requires the simultaneous use of multiple batteries, it's important to use batteries of the same type, specifications, and similar age to ensure optimal performance and stability when used together.

Mixing batteries with different capacities can lead to uneven discharge, charging imbalances, and potential safety risks. It's best to use batteries with similar capacities for optimal performance and safety.

Batteries heat up during charging due to the conversion of electrical energy into heat through internal reactions. Factors like internal impedance, charging speed, and battery type, especially in lithium-ion batteries, contribute to this heat.

While some heating is normal, excessive heat can affect battery life and performance. Using proper charging equipment helps ensure safe charging and reduces the risk of overheating.

To calculate the charging time, you should first identify the output current of the battery charger you're using. Then, use the formula:

Charging time (rough estimate) = Battery capacity / Output current
