5 of 5 Great Product at Excellent Price Tuesday, April 08, 2008
A Customer from Seattle WA  
I have been using these batteries for close to 2 years now, and they are still performing well. They are much better than the original batteries that came with the phone. The price here also was much cheaper than elsewhere.

This was the battery I was looking for. The price was right, and the shipping charge was appropriate. This is the second time I have bought batteries thru this site, and it is a breeze.

5 of 5 10X Better than OEM Tuesday, December 19, 2006
A Customer from St. Petersburg, FL  
This Ni-MH batter is 10x better than the old ni-cad. No memory effect, longer lasting, and better range. This is the battery that makes a good phone GREAT! Do not buy another Panasonic ni-cad.

5 of 5 Panasonic should have it in the phone to begin wit Thursday, January 19, 2006
B.Cook from Florence, SC  
ER-P511 works great I purchased one of these 6 months ago to replace the NiCd battery Panasonic provided with the phone. It's been great. It fits well (exact fit) and it provides long talk-times. Just the way Panasonic should have sold the phone to begin with.

5 of 5 The only Replacement to Use! Thursday, December 01, 2005
Al from Chapel Hill, NC  
Thank goodness someone finally made available a replacement for the P-P511 that is an actual improvement. Talk time is 5 times better on my phones...so good that I actually replaced a brand new P-P511 with the ER-P511. Great product and I highly recommend it!

5 of 5 Couldn't be better. Monday, May 09, 2005
toywlf from Atlanta, GA  
The factory-supplied battery died within 1-year. This is a workhorse battery that won't die, no matter how much I talk on the handset speakerphone. Highly recommended for < $11.

5 of 5 Great Battery - Great Price Wednesday, April 27, 2005
A Customer from Joliet, IL  
I orded 2 of the Energizer ER-P511 batteries to replace the stock battery in our Panasonic cordless phone handsets. With the original battery, the handset battery level was very unreliable - full power one minute, beeping due to low power the next minute. The ER-P511 battery has completely eliminated that problem and has been working perfectly! Also, the price at buy.com is great. Another electronics retailer that thinks they are the "best buy" (get it? :-) ) wanted about 2 1/2 times more than buy.com. Even with shipping, buy.com's prices was only about 1/2 of the retailer's price. Shame on Panasonic for not providing a better stock battery in the first place. The phone itself is great.

5 of 5 Great improvement over the stock battery Tuesday, February 22, 2005
F D H from Massachusetts  
This battery made a world of difference in the performance of my cordless telephone. I was ready to destroy my phone because the talking time was sooooo poor. Now I don't get the low battery beep unless it has been off its cradle for a few days.

5 of 5 GREAT BATTERY, GREAT PRICE!!! Wednesday, February 16, 2005
A Customer from Chicago, IL  
I have 4 of Panasonic cordless phones; their original batteries were always running out too quickly--those awful NiCd's were sooooo frustrating. Initially, I bought only two batteries because I was a little weary about the website and the low price, every other place I searched had the batteries for about double the price, the actual store prices were almost triple. I've had the batteries in use since the first week of Feb/05, and now, three weeks later I just ordered the other two batteries needed, also from Buy.com. The batteries are truly great! The batteries arrived quickly and well-packaged. Bravo!!!

5 of 5 A battery that finally lasts! Sunday, January 23, 2005
Allison from Huntington Beach, California  
We just ordered four of these batteries for our Panasonic expandable phone system and so far they have been great! The original batteries in our system would last at best 25 minutes before having to recharge. The new energizer batteries last for hours! Buy.com has the best price on this product and they are a fabulous company!

5 of 5 ER-P511 works great Monday, August 30, 2004
A Customer from Chicago, IL  
I purchased one of these 12 months ago to replace the NiCd battery Panasonic provided with the phone. It's been great. It fits well (exact fit) and it provides long talk-times. Just the way Panasonic should have sold the phone to begin with.
