We are happy to provided detailed information concerning the Uniden BT-446 battery below. We hope this education will give you the knowledge you need to make an informed buying decision when purchasing a replacement Uniden BT-446 battery pack for your Uniden cordless telephone.

What are the specifications of the Uniden BT-446 battery Pack?

Most Uniden BT446 batteries are rated at 3.6 volts and 800 mAh (Mili-Amp Hours). Sometimes you will see higher or lower mAh ratings. The mAh number is the measurement of the "capacity" of your BT-446 battery pack. The higher the Mili-Amp Hour rating, the longer your run time. For example, a 600 mAh cordless phone battery will give you twice as much talk time when compared to a 300 mAh (half of 600) battery pack. Also, it is important to note that the Uniden BT446 battery pack is composed of Nickel Metal-Hydride (NiMH) chemistry. This chemistry is known as "memory free" because the battery does not have to be discharged fully after everytime you use it before putting it back on the charger in order to avoid shortening its lifespan. Just use your phone normally and put it back on the charger when you are finished talking or no longer need the phone by your side.

What is the typical useful life of a Uniden BT-446 Battery Pack?

Most consumers get between 3 to 5 years of service out of their Uniden BT-446 phone battery before needing to replace it. The lifespan of course will depend on individual patterns of use.

Since this is one of our most popular batteries, we will be stocking fresh new BT-446 replacements for the next decade,

But I thought Uniden BT-446 batteries were rechargeable. Why do they wear out?

Certainly, the Uniden BT-446 battery is in fact rechargeable. Unfortunately, technologist still have not invented a perfect battery and since there is no such thing as a perpetual motion machine, the Uniden BT-446 will eventually need to be replaced. Every time you charge and discharge your Uniden BT-446 battery, a chemical reaction occurs to store or release the electricity to power your cordless telephone. Part of that chemical reaction uses a tiny portion of the NiMh chemistry in your Uniden BT-446 battery pack. Eventually those chemicals are depleted and your battery goes "dead".

My Uniden BT-446 battery has a yello wrapper. I see different colored telephone batteries available. Is that ok?

Yes, several different companies manufacture and market their own version of the Uniden BT-446 battery design to consumers. Many times these other battery manufacturers use different colored plastic shrink wrap as part of their own marketing and "branding" efforts. We have seen green, red, black, blue and tan to name a few! Rest assured, the color of your Uniden BT-446 plastic battery wrapping is unimportant. What is very important is that the form factor (size), polarity (orientation of the positive and negative contacts), connector (plug shape and size) and of course the voltage of your BT446 needs to be exactly the same.

How do I make certain I'm getting a quality replacement Uniden BT-446 battery pack?

Good question... Here is where you have to use some common sense and be a smart shopper. Sure, you can find websites selling replacement Uniden BT-446 batteries at prices from $4.95 to $21.99 for what looks like "the same" (at least in the pictures) Uniden BT-446 battery. Our experience indicates that it is true that you usually do "get what you pay for". In this particular example, there is definitely something wrong with the two extremes. Certainly $21.99 is way too much to pay for a Uniden BT-446 battery. Somebody is just trying to make a lot of money! And in most cases, $4.95 is just too good to be true. We get concerned about the quality of the materials (battery cells), safety features, and quality control process to insure the correct precision fit and finish of the BT-446 battery at that price. One has to wonder... is it a eally a brand new replacement BT446? Unfortunately there are probably some "refurbished" battery packs out there at some of those low prices. In addition many of these teaser rates do not include shipping or handling charges. Oftentimes that "$4.95" Uniden BT-446 cordless phone battery ends up being $15.99 or more after the hidden shipping and handling charges are added. One site that sells them at that price charges Nine dollars for shipping. So make sure you are looking at the final whole price of these "bargains". And remember to calculate the cost or replacing this "bargain battery" prematurely. We know the price is tempting - but it usually does not work out in the long run.

What should I look for when buying a replacement Uniden BT-446 battery?

If you are interested in buying a quality replacement for your Uniden BT-446 battery, go with a proven company that offers at least a one year no hassle warranty, gives you a toll free customer support telephone number, and clearly identifies the total cost of the purchase including any shipping or handling charges upfront.
