What is best practice for first use and over the lifetime of your Dell laptop battery
In this blog, we are going to discuss the correct way to use a battery once it's installed within a laptop. We will also talk about the correct way to charge and discharge the battery to prolong the batteries working life and save money.
The batteries first use
Once the battery is installed within the laptop it's best to allow the battery to fully charge before using it without a charger. Dell batteries have extra communication channels that detect the authenticity of the battery, the ware/usage, the temperature, and the capacity of the battery. This allows the cells to stay active and enables the laptop to calibrate and optimize battery usage.
I installed my battery and It's saying it's not genuine
If you get an error stating to battery your using isn't genuine. It could just be that the BIOS isn't up to date and the battery revision is newer than the BIOS. You can get the BIOS update from the Dell support page by entering your Dell service tag and following the instructions.
How to cycle a Dell laptop battery
With lithium-ion batteries its best to top-up the charge and not allow the battery to drop below 20-30% too often, this is due to Dell batteries having a limit to the number of full charge cycles.
How to physically help the life of the battery
Dell has safety data sheets (MSDS) and other documentation that not only cover the testing of a battery during and after the manufacturing process but details the storage and use of the battery but it can be very cryptic and difficult to read.
The documents state that:
Batteries shouldn't be exposed to extreme temperatures
The maximum working temperatures for Dell lithium-ion batteries are 0°C to 45°C (32°F to 113°F) If your computer gets hot. We would recommend getting it serviced as it could cause damage to the battery or laptop itself.
Dust build-up and blockages
When using the laptop, do not use the laptop on soft furnishings such as bed covers or cushions. This can not only block the fans but it can also cause the dust to build up within the laptop and clog the fan.
