Panasonic HHR-75AAA/B-6 Ni-MH Rechargeable Battery for Cordless Phones, 700 mAh (Pack of 6)

You can always use rechargeable batteries with higher capacity numbers, such as 700-800mAh instead of 630mAh. The phone will work exactly the same with higher mAh batteries, except for longer talk time between recharge cycles.

If you listen to everyone you may, as I did, end up with those that don’t work. If you want the phone to perform as well and as long as it did when you got it check the manual — it will tell you what you need battery wise and for any other replacement parts. You need the model # first and foremost. If no manual — lo… If you listen to everyone you may, as I did, end up with those that don’t work. If you want the phone to perform as well and as long as it did when you got it check the manual — it will tell you what you need battery wise and for any other replacement parts. You need the model # first and foremost. If no manual — look in the phone’s battery compartment and it’s above the batteries. For example, my phone is a KX-TGA680, and as it turned out, the manual for my model said it needed HHR-4DPA batteries. I thought the number on the original batteries in the phone was what I needed — turns out it wasn’t. I got the phone in 2013-14 and it’s still working though it’s gotten very scratchy sounding, cuts in and out, and doesn’t hold the charge very long.
If you need to find your manual, once you have the model #, 1) go to the Panasonic website (search Panasonic.com and it will come up na.Panasonic.com ; the na is for North America). Make sure you have the right website, no sales sites, etc. or so called instruction manual sites etc. Once at Panasonic, 2) go to the menu and select Sales and Support, 3) select Consumer Support, 4) you will see boxes – you want Instruction Manuals or select Telephones. Makes no difference both get you where you need to be. And then go from there putting your model number in the proper area. IMPORTANT NOTE: if your phone is more than 7 year old, save yourself time and trouble and go straight to “IF YOU KNOW YOUR PHONE IS MORE THAN 7 YEARS OLD” and follow the cues to where you put your model number in the box as indicated.
Whether an older model or newer, your manual will come up. Personally, I haven’t had good luck with off label batteries. I find they don’t last as long as the original ones, nor do they perform as well. After getting stuck a few times, I just won’t buy no name or not well known to most people. I also find it’s better to stick with the same brand of battery that came with the device no matter what it is. I want batteries with a company I know and can go back to if issues like they catch on fire etc. and destroy my device or worse. We have all seen these in the news to often and you have to wonder if it’s a cheap not well made battery. I hope this answer helps someone.

I would imagine so; all things being the same as the phone; need to be recharged. They are 1.5V rechargeable batteries.

You can always use rechargeable batteries with higher capacity numbers, such as 700mAh instead of 550mAh. The phone will work exactly the same with higher mAh batteries, except for longer talk time between recharge cycles.

They work fine in my KX-TGA101S even though it calls for HHR-55AAABU. Under "Customer Q & A’s", others have said they work in the KX-TGA402.

I’m sorry I don’t have the answer for you I just ordered the exact battery that was in my cordless phone regardless of the model number of the phone

I installed these batteries in my 5-line Panasonic phone system and they are perfect.
They are a standard "aaa" size.

Yes they are.

If your phone take AAA batteries then these will work great.

Yes this battery will work for you

If it takes t 3AAA batteries it seems logical.

They worked for me I have three phones KX-TGA1015 I l did one phone at a time and let them charge for 24 hrs.

I thought the same also but the new batteries worked out even better. Mha’s too small to worry about your chargers should work fine with upgraded batteries, go for it!

Replaced batteries in cordless Panasonic phones about 20 years old. Have worked great.

They are charged internally (in the phone) when the phone is on the base.

Pros…
1) I replaced the batteries for all 3 of my Panasonic home phones and immediately heard the difference! The phone had better clarity and felt like the phone could go for a bazillion hours without even the thought of going out.

2) The items shipped quickly and was received quickly.

Cons…
1) Everything should be free! Buuuuut that is just my take on it. Overall, from what I remember, the price was reasonable. The batteries were also a higher capacity than what I had which were the previous ni-mhes which lasted 12 years sooooo no complaints here. lol…

Summary…
If you are in the market for these type of batteries, you will likely be happy with this purchase.

I bought the Panasonic brand primarily because we have some Panasonic cordless phones in our home and I wanted to ensure 100% compatibility. Probably could have used other Ni-MH batteries, but these were by Panasonic and were indicated to be compatible with our phones. They were also price competitive, so it wasn’t a big financial choice make. Since replacing the old batteries with these new ones, our coreless phones do a great job at holding a charge and giving us good talk time.

At least a few years ago, maybe more we bought one of the Panasonic KX-TG6400 phone sets with a base and two handsets. For the past few months they’ve been acting flaky and not holding a charge for very long. With one of the sets, every time the phone rang it would shut off and display the "Charge for 7h" message. We talked about replacing them when it occurred to me it could just be the rechargeable batteries being worn down and sure enough, that was it.

The batteries are super-easy to replace, no tools needed. The bottom cover on the handset slides off, batteries pop-out. new batteries pop-in and cover snaps back on. The batteries do not come pre-charged so they needed the standard 7h charge.

All the handsets now work like they are brand-new. Perfect!

This was the perfect replacement battery set for our three 5yr old Panasonic house phones when one started to malfunction. They have a similar part number but the new batteries have a higher mAh than the originals. They are working with no issues in all three phones.

My wife had trouble with other aftermarket batteries, so I ordered these, and she is as happy as a lark. The batteries hold the charge for many days, and she likes being able to talk with sister without interruptions. A happy wife makes for happy life.

These were originally in the phones we bought. Best to use what came with your phones. I learned the hard way with my computers. Do not use cheap second hand Chinese made batteries in your equipment. You will be sorry like we were. Our carpets caught on fire and were damaged. The insurance company took care of it, but if we hadn’t been home, we could have lost everything. Use original equipment when you can.

My wife kept complaining about the short talk time on our phones so I was looking to replace them as we’ve had them many years and I thought maybe they were just worn out. Duh…they have batteries in the phones…MAYBE those are worn out? Anyway, these seem to be working out fine and I haven’t heard any of the moans about the phones so I think they have solved the immediate issue.

We are pleased with our new batteries. So far they work well. I did not respond to “longevity or battery life” because we just started using them about two weeks ago. Otherwise, no problems with the batteries.

The batteries were delivered as stated and placed on my porch. The batteries were enclosed in a ziplock bag in good condition. I ordered these for battery replacement in my Panasonic cordless phone. After installing in my phone, everything worked perfectly. The cost of the group of six batteries was economical when compared to other configurations offered by other vendors. I have no idea of how long they will last since I just installed them but Panasonic is a name I trust.

So far, so good.
I work from home and use my cordless phone ALL day for conference calls.
I prefer to have a seperate landline instead of VOIP, as my internet is not 100% stable. Besides, the sound on my phone is crystal clear and allows me to move around the house without being tappered to the desk/laptop.
This is the exact battery my Panasonic system uses. I will probably buy again soon, just to have a set on stand-by.
