Digital camera reviews of Energizer Er-P511 Replaces Panasonic P-P511Ý
Digital camera Review: 3 AA NiMH batteries, packing tape, aluminum foil, and scissors is all you need
Summary: 1 Stars
Tired of paying through the nose for these proprietary format batteries that deliver far less power than what is available out there in standard battery sizes ?
Well, make your own battery!
It turns out that this particular battery, designed to replace the dreadful OEM Panasonic P-P511 battery (a NiCad 850mAH battery), is pretty easy to build yourself, as long as you are somewhat handy with arts and crafts. You don't have to know too much about electronics to build this battery.
First of all, save the original P-P511 battery that came with your phone. Study it. The P-P511 battery is essentially made of three AA batteries linked together in series. Linking batteries in series just requires that the minus pole of one battery contact the positive pole of the next battery, and so on. These links can be made by using wires or strips of metal.
Take an Exacto knife or something similar and cut/peel away the outer plastic wrap of the battery. The bottom part of this old battery will have a hard plastic frame that holds the three AA batteries together. Save this plastic frame for re-use.
Next, note how the original three AA batteries are linked together. The alignment of the three batteries is such that the one on the left will have the minus pole down, the one in the middle will also have the minus pole down, and the one on the right will have the positive pole down. The plastic holder has two holes, one in the middle, and one on the right side to allow the middle battery's minus pole to contact the handset's spring leads, and the right side battery's positive pole to contact the handset's spring leads.
OK, so now all you've got to do is figure out how to hook up the batteries in series so that these two battery poles end up at each end of this daisy chain series.
Take heavy duty packing tape and some heavy duty aluminum foil (the kind that comes in the large heavy duty lengths work fine), and cut small 1/4 inch strips. Tape the end of one such aluminum strip to the minus pole of what will be the left hand battery. Run this aluminum strip flush along the body of the left battery to the other end of the battery, and tape the other end of the aluminum strip to the positive pole of the middle battery.
Next, tape these two batteries to the plastic frame holder and cover up the aluminum foil generously with some of the packing tape. The next aluminum strip needs to run directly over the positive pole of the middle battery without making any electrical contact with it, so the positive pole of this middle battery needs to be well covered with tape and insulated.
So, tape down one end of a strip of aluminum foil to the top minus pole of the right hand battery, and run the foil strip across the top of the middle battery, and make contact with the bare positive pole of the left hand battery. Tape dowm the aluminum foil to the top of the left hand battery.
Tape the right hand battery to the other two batteries and the frame, and then wrap the whole group of three batteries in tape again, just to make sure the whole thing stays together.
Voila! You've made your own P-P511 battery!
The reason for doing all of this is of course that the technology for NiMH batteries has far outstripped what is being offered in this battery here (only 1200 mAH!), and you can make yourself a far better battery.
The batteries that I used were Everyready Energizer 2500 mAH NiMH type. Way better than the original, way better than this Everyready ER-P511!
Addendum - the best NiMH batteries at holding a charge that I've found are the Eneloops by Sanyo. The Energizer NiMH batteries I originally mentioned above turned out to have this bad tendency to lose their charge after a few months. Thanks to the comment by Casey for reminding me to update this review.
Digital camera Review: Another home made battery user here!
Summary: 1 Stars
After reading these revues I got a pack of Duracell 2650 mAh AA NiMH batteries and made my own with aluminium foil and electricians tape. Works great and the range is AT LEAST doubled!
Best of all, it only cost $12, vs. ~$20 for a "real" battery!
Digital camera Review: BETTER PHONE BATTERY FROM ENERGIZER
Summary: 5 Stars
I have four digital phones in the home from Panasonic and have used Radio Shack and Panasonic batteries in the past with minimal life. The Energizer battery exceeds the life of the others. I used an Energizer in the past and forgot the benefit and went with Radio Shack and was sorry for the change!!!!Digital camera Review: Be careful what you buy!
Summary: 1 Stars
I purchased several of these batteries at a signifcant discount from local companies. Now I know why they were "significantly less" than local retailers....they don't last half as long!!!! Might be cheaper, but in the long run, paying full price an honest retailer is worth it!! Very disappointed in the performance of these batteries!Digital camera Review: Best Replacement
Summary: 4 Stars
Kept my phone system working. Tried other cheaper off brand batteries, returned some after 2 weeks and even the replacements didn't last. Finally threw them away after using these.
