Tips about how to make your J399N laptop battery last longer?

  1. Best way to charge/preserve a new Dell J399N battery
    A: It's better to charge the battery fully and then allow it to sit after charging to stabilise. Then use it as you wish down to full discharge so that the laptop goes to sleep at its designated discharge level. Leave the laptop on sleep at least 5 hours or until it seems totally dead and then recharge from the mains. Again allow J399N battery to rest and then use it normally for the next month.
  2. Tips about how to preserve your J399N battery life
    A: Do not overcharege or disovercharge your battery frequently.Don not setting a metaillic object on your Rechargeable J399N batteries connect metal or it maybe short circuit terminals. And avoid heat, heat is the battery enemy, the temperature in a car can easily rise 50F in a single hour, in some cases reaching 140F.
  3. Don’t keep J399N batteries stored for long periods of time- While it’s nice to have spare batteries around, laptop batteries are always losing at least a small bit of their charge. Assess your replacement laptop battery needs, and keep yourself supplied accordingly.
  4. Never short a battery to fully drain it. By short, I mean that you connect the two terminals (positive and negative) directly so that the Dell J399N battery simply drains. This is a very bad, stupid thing to do. It can cause a fire. Don't do it.
