Customer Reviews

Much better than the Panasonic battery
I think the Panasonic expandable cordless phone systems are great... I've used several of them at home and at work for the last two years.
However, the Panasonic battery life is not very good, even when brand new.
This Energizer replacement battery is much better.
I no longer have to worry about making certain to put the phone back on the charger every night.

Price Confusion
I agree with all the reviewers regarding the factory installed Panasonic batteries vs. the higher quality Energizer replacement batteries. What really threw me is the drastic difference in prices for ths same product (ER-P511). I noticed that at one dealer alone, in this case DB-Roth, they had 4 different prices for the exact same product. The prices ranged from $6.99 - $10.49. However, finding the best deal is not as simple as choosing the lowest priced item. Once I added in shipping, prices for 5 of the batteries (I wanted to have extras for our phones) ranged from $51.34 - $65.54. Strangely, the lowest total price came from the batteries that were listed at $8.95 each.

I ended up buying from DB-Roth simply because I was sick of comparing prices, but I would not be surprised if there is a cheaper alternative out there. I advise everyone to compare prices, even within the same dealer, to be sure you're getting the best deal offered.

WORKS WELL!!!
Much more efficient than the original Panasonic batteries. They last much longer. Amazon has these cheaper though. Get them from Energizer instead of Eveready. Same thing for less. $9.95 new instead of $12.95. They are just like the Energizer Bunny. It keeps going and going and....
