How to Keep Your HP Presario CQ70 Laptop Battery Alive

A little maintenance will keep your battery charged through the cold months as well as the warmer ones.

Way to Keep Your HP Presario CQ70 Laptop Battery Alive

1. Estimate the age of your HP Presario CQ70 battery. If it’s more than 4 years old, replace it.

2. Ask your mechanic to perform a ‘load test’ on your laptop battery. This tests whether the battery is capable of generating sufficient charge on below-freezing days. If it fails the test, replace the battery.

3. Clean the battery terminals if they are encrusted with deposits. Use a wire brush dipped in baking soda and water to clean them of corrosion and ensure that the deposits do not block the flow of electrical current.

4. Check to make sure the water level in the HP Presario CQ70 notebook battery hasn’t dropped. You can do this on conventional batteries by popping off the plastic cover and checking to see that the water inside reaches the plastic filler necks.

5. Check the tightness of the battery cable ends. A loose Presario cq60 Battery connection can prevent your car from starting and acts just like a dead battery. If you can move the battery cable ends that are attached to the battery terminals at all, they are too loose.

6. Check that the battery is securely fastened in the battery tray. A loose HP presario battery that’s allowed to shift around can cause damage if it is able to tip over under the hood. Excessive vibration will also shorten the life of your HP presario laptop battery.
