  2. If you don't plan on using the battery for a month or more, we recommend storing it in a clean, dry, cool place away from heat and metal objects. Li-ion batteries will self-discharge during storage, remember to break them in before use.
  3. Do not drop, hit or otherwise abuse the battery as this may result in the exposure of the cell contents, which are corrosive.
  4. Lenovo l12s4e21 battery packs should ba charged for 12 hours when you first get them.
  5. Laptop batteries are completely dischardged at the time of purchase and need a full charge before their first use.
  6. Please store laptop battery in a fully charged state and kept in a cool, dry and clean place.
  7. When charging your lenovo l12s4e21 notebook battery for the first time your computer may indicate that charging is complete after just 10 or 15 minutes. Don’t worry, this is normal with rechargeable batteries. Just simply remove the lenovo l12s4e21 from the laptop and repeat the charging procedure.
  8. Do not expose the battery pack to direct sunlight. Never store or use the battery pack in an unventilated vehicle where excessive internal temperatures may be encountered.
  9. It's a good idea to clean dirty lenovo l12s4e21 battery contacts with a cotton swab and alcohol. This helps maintain a good connection between the battery and your portable device.
  10. As the rechargeable lenovo l12s4e21 battery begins to die, the user will notice a decline in the running time of the battery.
