Sometimes its a crap shoot buying batteries for your cordless phone. i've even gone to a retailer and they've screwed up just looking at the package.I like that these batteries are not only very reasonably priced but that they show a good picture of the connector at the end of the cord. it looked like it would be compatible with what i was looking at - already in my phone.fit perfectly and after charging is working like a charm and holding the charge very well!

Did not have any issues with delivery, in fact they arrived almost immediately. These batteries last me over a year, which I'm satisfied with. Once they are plugged into the phone, they are instantly charged and I can use the phone right away. They have allowed me to continue to use my V Tech phones - all 4 of them - and not have to worry about running to the local stores to purchase them at a cost of twenty dollars each. So the cost factor alone makes for considerable savings. Satisfied customer.

The original batteries in my V-Tech phones, four of them, worked well for about 6 years, and then progressively failed, one by one. After an Internet search, I bought 6 of these battery packs with the hope that at least four of them would work. The first four of these replacement batteries appear to work very well! They were partially charged as I got them and they quickly charged when put in service. I am very pleased to have my array of V-Tech phones back working correctly. My concern is how long these inexpensive battery packs will last. I am hoping for several years, at least. But we are off to a good start, and I hope I don't know the answer for several years.

Purchased Sep 29, 2013. I was originally getting 9-10 days of stand-by time. 15 months later and the battery is still going strong though I now only get about 5-6 days of stand-by time. I don't really use the phone all that much, maybe 30 min. a day on average, and I only place it back on the charger when the phone beeps that the battery is low.Rechargeable batteries have a certain number of discharge/charge cycles. You don't want to put the phone back on the charger after each use if it doesn't need a charge. Doing so will use up those cycles and shorten the useful life of the battery.At the rate the battery is holding up, I probably won't need to replace it for another year. The original AT&T battery (3.6V and 600 mAh) lasted about 3 years. This one is 3.6v and 800 mAh. The higher the mAh (milliampere-hour), the longer the charge.For under $3 and what will probably be 2.5 years of use, this is a bargain.

Before I got the new battery My pphone would only last at the most 2 minutes. I put the new battery in and it last! I hope they stay in busisness so I can order again when I need to.

I have a V Tech phone set that I bought at Costco like 8 years ago and they are still going strong. When one of them stopped charging my first thought was that they were finally going out. I took a shot on these batteries and the problem is solved! Why replace your whole set because of one battery? Cheap and worked.Note: these batteries need to be disposed of correctly. They can't be thrown in the landfills (trash can). Search the net for local places that take your batteries and dispose of them so we don't have the bad stuff leach in to our water system. Please!

This replaced a 10 year old battery in an AT&T handset. Phone powered right up and is working fine. I have not had the new battery long enough to rate it on longevity. I have had several 45- 60 minute calls with no issues or low battery warnings.

My order appears to be lost in mail contacted seller needed repl overnited seller refuses.- : -It is apparent the items are lost in the mail. Items purchased on 1/7 seller shipped on 1/8 yet tracking info shows shipped 1/18 out of Salt Lake City as of 1/23 they are still in Salt Lake City Utah? I contacted the seller explaining that I needed replacements sent immediately. I am a disabled senior and I only have my land line and all the batteries in my 4 cordless phones died at the same time. (I thought this strange but after speaking to others who have had the same thing happen, it seems to be common when you buy a new phone system where batteries are incl, which this was.) I explained to the seller that I do not own a cell phone and my only way to contact emergency services if needed are with my cordless phone. I begged him to send replacements overnite and that if the original order ever arrived I would return it to him. I also asked if he would only overnite 1 ($3) battery so I would at least have a phone until the missing order arrived and the seller still declined to help. I have now been forced to purchase from another seller w/guaranteed delivery by Thursday 1/24. I will be returning the batteries from this seller if they ever arrive but need to file a claim with Amazon now and cannot wait longer. I am a senior on a fixed income and cannot afford paying for these batteries twice in one month and desperately need a refund for the missing order.Amazon kindly gave me a credit so I wouldnt have to wait. NOTE I wanted to work out this situation and I tryed but this seller was not willing to make an exception.
