You might find the model number printed on the telephone casing, on the underside the rear compartment cover, or inside the compartment. Sometimes, the exact power pack type will be printed inside the compartment so that you know exactly what you're looking for.

What causes a telephone battery to stop charging?

There are several reasons why cordless phone batteries may fail to charge. Those reasons are the fact that batteries fail, chargers go bad, and telephones stop working. If you go ahead with replacement and the new one won't charge, you know it could be the Uniden telephone or charger.

What are the symptoms of a low telephone battery?

You might notice that the telephone isn't holding a charge as long as it used to. However, call quality can decline, the phone dies within seconds of the low power beep sounding, and onscreen indicators may turn on not long after a full charge.

Can you use a higher mAH battery in your telephone?

You can use a higher capacity battery in your Uniden telephone. However, you must make sure that the power pack types are the same.
