*Compare price range and warranty details.

Prices for usually range from $50 to $150. Start with your laptop manufacturer’s Web site or telephone sales department. Get a price for a replacement battery, and make sure you find all the warranty details.

*Check the Internet for third-party battery suppliers.

You may find the identical name-brand battery for less. And you may also be offered Brand X replacements at a significantly lower price; some of the third-party laptop batteries even promise to hold a larger charge. However, pay close attention to the warranty; what happens in the one-in-a-million-or-so situation where a battery overheats or otherwise damages your laptop?

*Meet the specifications.

You can’t squeeze a 3-inch battery made for a Dell laptop into the 2-inch slot on a Toshiba laptop battery. It’s physically impossible, and even if you could squeeze it in, the electrical connectors probably wouldn’t line up.

*Match the voltage.

If your original battery was rated at 14.8 volts, that’s the ticket for the replacement model. Don’t go over or under the specified power.

*Consider going high capacity.

Within the manufacturer’s specifications, you may be able to replace your original battery (such as hp laptop battery)with one with a higher watt-hour or amp hour rating. This allows you to work longer.

*Get fresh.

You’ve no good reason to buy a used battery (or an unused model that has been collecting dust on a shelf somewhere). Check the date of manufacture; anything older than about 18 months should be suspect.
