Work as BT1015 replacement

I was surprised at the quality build of these batteries at such an amazing price. I bought them as replacements for BT1015 bats in our old Uniden phones. With some wiggling around the bats fit into the phones and the connector plugged right into the receptacle. These new ones hold more power than the old. Mine arrived with a low level of charge (rather than empty) so you could see the phone was working right away. Very pleased with this purchase and the fact that I can update all our phones with new bats at the same time.

Five Stars

These batteries work great in my Uniden cordless phones. I have a phone system with 3 phones total. One sits on a base with an anwering machine, while the other two have seperate charger bases, allowing them to be placed in different rooms throughout the house. Two of my three units were starting to act up -hanging up at random, cutting in & out, etc. I figured it was time for a new set of phones which would easily cost me at least around $100. I decided to price out replacement batteries, first. In the store, they were about $15 each. Paying $45 just to find out if the it was the problem or not did not appeal to me. I started checking around on Amazon for the type of phone system I needed. In my search, I turned up these replacement batteries, and decided to give them a shot. The item had 100% positive reviews, and cost about what one battery would have cost me in the store, for a pack of five. The batteries arrived quickly, and worked perfectly. I have now had them for about a year, and they are still performing perfectly. I am SO glad that I decided to give these a try instead of buying all new phones.

Perfect!

I bought this for the computer that I have had since college - eek. The battery I needed to replace wouldn't hold a charge for more than twenty minutes. When I got this one, it was well-packaged, and it fit perfectly with my computer - no issues at all. Now I don't have to drag my charger around the apartment anymore.

Customer Service is wonderful.

The first battery I bought went in just fine and seemed to work, except it didn't. The laptop continuously would not recognize it, then would, back and forth, making it unable to charge the battery, let alone use the laptop because it would freeze trying to figure out what to do. I went online to ask about solutions, but found no way to do so. (fault probably on my end) I got an email from the company, asking what the problem was based on the review I left. They sent another batter without even my asking, and knowing I was past amazons return date. The new battery is working just fine. I will see in a few days, but it shows no symptoms of the problems the previous battery had. Over all I am very happy with this seller and the battery, and am pleased there is still customer service out there that knows what that means.

Saved me from buying another $100+ set of home phones!

We have spotty cell service in our house so we need a reliable land line. Our old uniden phones (see photo) just didn't hold a battery charge for longer than a 10 minute conversation and we were at a tough situation of spending a bunch of money on new phones for a landline phone that we rarely use. The brand replacement batteries were insanely expensive and not even worth it! These work amazing! They fit without any problems, were very affordable and came with some charge. I have yet to have a phone die on me in mid conversation so I can't even say how long they last, but long enough to never be an issue for me! I've had these for a couple months now with no issues whatsoever. We have 3 phones so we used all three batteries immediately and all work. I see absolutely no negative points to buying these.

Makeso your laptop last longer!

Worked out great! Renews the life of our laptop! Fit perfectly!

Great replacement for OEM batteries in my wireless phones!

Good delivery. I bought them for my Uniden wireless phones to replace the 10-year old batteries in the phones. The URPower packs were identical replacements, both in size and connector/wiring. I had no problems replacing the originals with the URPower battery packs. The battery packs all had a partial charge when I got them. I've had them in service for a week now, and have no problems with any of them.

Perfect!

This is an excellent backup battery. My computer loses charge when I'm out and about all day. I needed a back up, and this works perfect. It is easy to charge and holds a battery for a long time. No issues with fit on my laptop. Now I can use my laptop much longer when I'm not able to keep it plugged in all day.

Seems Good so Far

Fit perfectly and works well, although I’ve only had it for a few days. Longevity and durability ratings will have to wait, but I’m optimistic thus far.

After 5 years, our 5 phone system started having trouble holding a charge. One handset stopped charging completely (which finally prompted a purchase). These were less expensive than oem and stated that they hold more charge. Batteries fit properly in the handset and didn't have any trouble with the connectors. I have never really been one to have extended phone conversations, so I can't provide an opinion on improved talk time duration.
