Washington: With cases of cell phone batteries overheating increasing, it is vital to keep the phones safe and an expert has revealed how.

CNET technology contributor Katie Linendoll explained the most popular type of battery in most electronic devices now is a lithium ion battery because in many cases they hold six times the charge and are lightweight, which is perfect for portable consumer electronics including laptops, mp3 players and cell phones, reports CBS News.

Here are some of the tips Linendoll offered for the devices:

Don`t buy a counterfeit

Rapid growth in counterfeits equals loss of quality control. Understand these units are built cheaply. Counterfeit phones and other electronics are an estimated 100 billion dollars global problem. So be wary of too-good-to-be-true deals on eBay and Craigslist. Ask questions like, "Is there a legitimate model number on the phone that matches with the manufacturers website?"

Protect from heat and water

Heat and electronics don`t mix. It`s easy to miss places as simple as a cooking surface in the kitchen or leaving your phone in your car. Your car your car is a heat box. Sun can fry it in one grocery run.

Water and electronics don`t mix. Do not get your phone or battery wet. It might appear to be fine, but could lead to corrosion and eventually a short-circuit. And water damage isn`t typically covered by warranties.

Heed the warning signs of a defective

If your device is becoming very hot and is uncomfortable to touch, it`s probably a sign of something wrong with the battery.

Make sure cell phone is compatible with batteries and chargers

Every charger is designed to match a certain voltage and current level - if it doesn`t match, it could fry it. If you`re not sure, call the manufacturer. Just because the plug sits in your phone, doesn`t mean it`s right.
