What are the specifications of the Panasonic P-P504 battery Pack?

Most Panasonic PP504 batteries are rated at 3.6 volts and between 500 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 P-P504 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 typical useful life of a Panasonic P-P504 Battery Pack?

Most consumers get between 3 to 5 years of service out of their Panasonic P-P504 phone battery before needing to replace it. This lifespan absolutely depends, of course, on individual patterns of usage.

But I thought Panasonic P-P504 batteries were rechargeable. Why do they wear out?

True, the Panasonic PP504 battery is in fact rechargeable. Unfortunately, we still have not invented a perfect battery and since there is no such thing as a perpetual motion machine, the Panasonic PP-504 will eventually need to be replaced. Every time you charge and discharge your Panasonic P-P504 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 NiCd chemistry in your Panasonic P-P504 battery pack. Eventually those chemicals are depleted and your battery goes "dead".

My Panasonic P-P504 battery has a black wrapper. I see different colored telephone batteries available. Is that ok?

Yes, several different companies manufacture and market their own version of the Panasonic P-P504 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, yellow, blue and tan to name a few! Rest assured, the color of your Panasonic P-P504 plastic battery wrapping is unimportant. What is important is that the form factor (size), contact (plug), polarity (orientation of the positive and negative contacts) and of course the voltage of your PP504 need to be exactly the same.

How do I make certain I'm getting a quality replacement Panasonic P-P504 battery pack?

Here is where you have to use some common sense and be a wise shopper. Sure, you can find websites selling replacement Panasonic P-P504 batteries at prices from $5.95 to $19.99 for what looks like "the same" (in the pictures at least) Panasonic PP504 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 $19.99 is too much to pay for a Panasonic P-P504 battery. And, in most cases, $5.95 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 P-P504 battery. One has to wonder - is it a brand new P-P504? Unfortunately there are probably some "refurbished" or damaged goods out there at some of those low prices. In addition many of these low teaser rates do not include shipping or handling charges. Oftentimes that "$5.95" Panasonic P-P504 cordless phone battery ends up being $15.99 or more after the hidden shipping and handling charges are added. So make sure you are looking at the final total price of these "bargains".

What should I look for when buying a replacement Panasonic P-P504 battery?

If you are interested in buying a quality replacement for your Panasonic P-P504 battery, go with a proven company that offers at least a 30 day money back guarantee, 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.
