Battery Aa Rechargeable


I ordered the batteries for my phone because I thought that I was getting the Panasonic Brand at a great price. What I got was a "generic" which I had to pay to return.

I find it difficult to find this specific battery - Panasonic Brand - at any stores. For the cost that you would pay for 8 of these real Panasonic batteries - you could buy a new 4 phone system. Panasonic NiMH AAA Rechargeable Battery for Cordless Phones (HHR-4DPA/2B)

I purchased this bet of batteries thinking, "What a Great deal!" I was let down when I opened the box and discovered a cheap Chinese knock-off. You know hte old saying "If it looks too good to be true, then it probably is too good to be true. This applies to this set of batteries. They do work in the phone but they aren't as advertised. You be the judge!

Dr...

As many other reviewers have found out: depending on from which vendor you order those Panasonic NiMH AAA Rechargeable Battery for Cordless Phones, you may receive either the genuine Panasonic brand, or some off-brand substitutes. Neither outcome is a good deal in my opinion. Allow me to explain...



Check the battery compartment of your Panasonic cordless phone (for example, the Panasonic KX-TG1062M DECT 6.0 Cordless/Corded Phone). If you see just two loose AAA cells instead of a battery pack, you're in luck! You can put any AAA rechargeable NiMH cells in there, and the phone won't know the difference. When the handset is placed into the charging cradle, the charger won't know the difference either. So it will just continue to charge the batteries at a low current (around 50mA). As long as your replacement batteries have capacity equal or higher than the original batteries, you are good to go.



That said, I highly recommend getting some good-quality LSD (Low-Self-Discharge, also known as 'Pre-Charged') rechargeable batteries, instead of either genuine Panasonic brand or off-brand rechargeable batteries. This is because:



1. Genuine Panasonic batteries have capacities of 550-650mAh, which is very low by today's standard for AAA rechargeable NiMH cells. Also note that Panasonic is not a battery manufacturer. So those 'Panasonic' batteries are just rebranded cells from some unknown battery maker.



2. Off-brand batteries advertise higher capacities such as '1000mAh', but they usually suffer from rapid self-discharge problem. That means if you leave the handset outside the cradle for just a few days, the batteries will be dead due to self-discharge.



3. LSD batteries are pre-charged from the factory, and they are ready to use right out of the package. That means you can start using your phone with those batteries right away, instead of having to charge the handset for several hours before testing.



As of this writing, you can set a set of 4 good-quality LSD cells for about the same price as just two of those 'Panasonic' batteries. Consider, for examples:

- Sanyo eneloop AAA Pre-Charged Rechargeable Batteries (800mAh)

- Rayovac Hybrid - Battery 4 x AAA NiMH (800mAh)

- GP ReCyko AAA Rechargeable Batteries Pre-Charged (850mAh)

- Tenergy Centura AAA Low Self-Discharge NiMH Rechargeable Batteries (850mAh)



All those batteries above offer higher capacity than the original Panasonic batteries. Furthermore, you get batteries with known quality, instead of trying your luck. That may be more important than cost-saving alone.

I just ordered and received these a couple of weeks ago, they are exactly as pictured on the product page, the same Panasonic batteries that came with the new phone. For whatever reason, it looks like the company switched as of this year, as it looks like most or all of the 2010 reviews are saying that the Panasonic brand batteries are what they got.



When i needed new batteries for one of my phones, i looked on Amazon, found these batteries, read a few reviews and only saw reviews saying that the off brand batteries were received. Those who got the off brand and kept them did not mention any problems with them, and since i needed the batteries and didn't have time to shop around locally for them, and because i think most things like batteries are probably made in China anyway, including the brand name ones, i went ahead and ordered some, expecting them to be OK either way.



What i received were the Panasonic batteries as pictured. They are working fine so far.

I ordered these to replace the rechargeable AAA batteries in my Panasonic phones. I had read reviews of previous purchasers who said even though the batteries worked they were NOT Panasonic branded. As far as I can tell, the ones I received ARE Panasonic branded and appear to work great. Thanks Amazon, You're my best friend.

I bought what I thought were a pack of 4 but it was only a pack of 2. They did not have a picture of the prduct otherwise I would have seen it was only two. Sony's similar product comes in a pack of 4 and is only .14 cents more.

Suggest Duracell AAA "precharged" rechargeable batteries:



Our Panasonic original batteries (the ones that came with the phone) died quickly in one of our phones (the other phone is doing ok). I'm sure the manufacturer would not recommend this, and you'd have to try it at your own risk, but we tried Duracell AAA "precharged" rechargeable batteries (these hold their charge for months) and so far they've been working great! Nice thing is you can get these at most any store. We just let them charge in the phone charger (e.g. we do not take them out to charge them separately in a Duracell charger) and they've been fine so far.



This saved us hunting around for "Panasonic specific" batteries, hoping the were good quality, etc.'
