Digital camera reviews of Energizer Er-P511 Replaces Panasonic P-P511Ý
Digital camera Review: Replace those horrible Panasonic batteries with this one
Summary: 5 Stars
The batteries that come with the Panasonic phone are terrible, dying very quickly. After several frustrating months and having replaced them twice, we tried this battery and it's 1000 times better! Highly recommended.Digital camera Review: S&H Cost is more than the battery
Summary: 5 Stars
$7 might be a good deal for this battery, but the shipping and handling charge is $11.50 for one battery, $17.50 for two. I am not sure how the seller, eek Technology can get away with this, but if Amazon doesn't have a problem with it, perhaps they can sell the batteries for $2 each to draw in customers and hope they don't notice the $16.50 S&H charge.
I'll check if Radio Shack sells them locally.
Digital camera Review: So easy. works great
Summary: 5 Stars
So easy to order. phone works great with this battery (much better than the original batteries the phone came with).Digital camera Review: The heck with these expensive batteries. Make your own replacement battery!
Summary: 1 Stars
One star because they are too expensive for what you get. You can make them cheaper:
I own 5 Panasonic KX-TG2720 telephones. I bought them new on clearance for $20 a piece. They were probably on clearance since they came with the terrible, Panasonic P-P511 Nickel Cadmium recharable batteries that lasted less than 6 months. NiCad batteries are terrible since they are plagued by "memory" and a relatively short life span. This is likely why Panasonic discontinued the P-P511 NiCad and replaced it with the HHR-P402 Nickel Metal Hydride. This step was an improvement but it should have come with the phone in the first place.
Replacement battery packs for Panasonic phones are not cheap. They generally run over $10 a piece. Therefore, I took DarthRad's advice below and made my own using Duracell DC1500 2500mAh NiMH batteries. I bought four 4-packs for about $28 and made 5 replacement recharable battery packs for the Panasonic phones. Since each recharable battery pack uses 3 batteries, I had one left over.
I embarked on this project for 3 reasons:
1. You can save a lot of money
2. You can make a far better recharable battery pack since even the ER-P511 is only 1500mAh as opposed to the Duracells which are 2500mAh (this translates into longer talk time and increased range)
3. I like excuses to the use a soldering iron.
I will not repeat DarthRad's great instructions below but I will say that I was able to use all of the materials of my existing NiCad batteries for use when I ran the Duracell's in electrical series. Therefore, I did not need to find some aluminum foil as DarthRad suggested.
I carefully extracted the 2 strips of thin aluminum. (For the purposes of description, if you open the back of the handset, battery #1 is on the left and the bottom of battery #1 is covered by the plastic at the bottom.) There is one aluminum strip on the top between battery #1 and battery #3 and another longer strip that runs from the top of battery #2 to the bottom of battery #1.
Instead of tape, as DarthRad suggested, I used a small amount of solder to hold the aluminum strips in place. I suppose you could use tape but it is not as secure as using a soldering iron.
I will mention that commercial batteries have a small 'nub' on the positive terminal so they are slightly taller than those I replaced in the recharable battery pack that did not have a nub. This really did not matter all that much. They will still fit in the handset. I imagine if you had to use tape to secure the aluminum strips, it may be a tighter squeeze.
THE RESULT: Cheaper, better batteries that last longer and enable a longer range from the base. Plus you have a good sense of accomplishment. ...There is nothing to it. And no, you won't burn down the house. The home made packs are no different in functionality over the ER-P511.
Digital camera Review: This will last for almost 2 years
Summary: 4 Stars
This will last for almost 2 years which is better than the original Panasonic one. Those last for only 3 months. This battery makes the Panasonic phone work as advertised; I could use the speaker phone for the first time. The price is lowest but the shipping is a rip off. I was about to checkout and then noticed the high shipping. Finally brought this from Cyber gift center.
