 Don't over-pay for generic AAA rechargeable batteries Aug 13, 2011
By NLee the Engineer
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 550-630mAh, which is very low by today's standard for AAA rechargeable NiMH cells.
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.

 GENERIC PANASONIC SUBSTITUTE Nov 15, 2009
By C. ROWE
"ECOMOM2008"
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.

Bofore you purchase those 'Panasonic' brand replacement batteries, check the battery compartment of your cordless phone (for example, the Panasonic KX-TG1062M DECT 6.0 Cordless/Corded Phone).

1. Genuine Panasonic batteries have capacity of 550-630mAh, 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.

Not A Panasonic Battery as advertised Oct 29, 2009
By Jeffrey V. Ferguson
"dr.ashtray"
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!
