What exactly is a Sony BP-T23?

Sony BP-T23

The Sony BP-T23 is a cordless telephone battery used in over 800 different mostly Sony telephones. The battery is also used in many AT&T, Panasonic and V-tech cordless telephones as well.

We have provided details concerning the Sony BP-T23 battery in the discussion that follows. Hopefully this information will give you the knowledge you need to make a more educated decision when purchasing a replacement Sony BP-T23 battery pack for your telephone.

What are the specifications of the battery Pack?

Most Sony BPT23 batteries are rated at 3.6 volts and 700 mAh (Mili-Amp Hours). Sometimes you will see higher or lower mAh ratings. The mAh number is the measurement of the "capacity" of your BP-T23 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.

What is the normal useful life of a Sony BP-T23 Battery Pack?

Most consumers get between 3 to 5 years of service from their Sony BP-T23 phone battery before needing a replacement. This lifespan depends, of course, on individual patterns of usage.

But I thought all Sony BP-T23 batteries were rechargeable. So why do they wear out?

True, the Sony BP-T23 battery is a rechargeable battery pack. Unfortunately, we still have not yet invented "the perfect battery" and since there is no such thing as a perpetual motion machine, the Sony BP-T23 will eventually need to be replaced. Every time you charge and discharge your Sony BP-T23 battery, a chemical reaction occurs inside the battery cells to store or release the electricity you need to power your cordless telephone. Part of that chemical reaction uses up a tiny portion of the NiMh chemistry in your Sony BP-T23 battery pack. Eventually those chemicals are depleted and once that happens, your battery goes "dead".

My Sony BP-T23 battery has a black wrapper. I see different colored telephone battery packs available. What is the deal? Is that ok?

Yes, that is ok. Several different companies manufacture and market their own version of the Sony BP-T23 battery design to customers. Many times these battery manufacturers use different colored plastic shrink wrap as part of their marketing and "branding" efforts. We have seen green, white, blue, red, yellow and tan to name a few! Rest assured, the color of your Sony BP-T23 plastic battery wrapping is cosmetic only and unimportant. What is very important is that the form factor (size), polarity (orientation of the positive and negative contacts) and of course the voltage of your BPT23 - all must be exactly the same.

How do I make certain I'm getting a quality replacement BP-T23 battery pack?

That is a good question. It is difficult to sort out the variety of offerings out there on the internet. You can find websites selling replacement Sony BP-T23 batteries at prices from $7.95 to $19.99 for what looks like "the same" (in the pictures at least) Sony BP-T23 battery. Our experience indicates that it is true - you usually do "get what you pay for". So you need to use some common sense. In this particular example, there is definitely something wrong with the two price extremes. Certainly $19.99 is way too much to pay for a Sony BP-T23 battery pack. Somebody is just trying to make a lot of money! And in most cases, $7.95 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 BP-T23 battery. At some of these low prices, one has to wonder - if it is is in fact a brand new BP-T23? Unfortunately there are probably some "refurbished" or damaged goods out there on the market. In addition many of these low teaser rates do not include shipping or handling charges. Oftentimes that "$7.95" Sony BP-T23 cordless phone battery ends up being $16.99 or more after the hidden shipping and handling charges are added at the end of your checkout proceedure. So make sure you are looking at the final whole price of these "great deals".

What should I look for when buying a replacement Sony BP-T23 battery?
