As my original battery of the Samsung S3 mini was having issues, i needed a new one. These replacement batteries by Hausbel are a great alternative to the original ones as you get a pair, instead of just one. These batteries were delivered on time and came nicely packaged (see photos). They fit my phone perfectly and so far i am getting a good performance of my phone. The second battery always comes in handy if you have a portable external charger.  Personally i am totally satisfied with these batteries. I received this product at a discount in exchange of my honest and unbiased review.

These batteries hold a charge longer than the oem batteries and are much less expensive. The cells in these are also replaceable unlike the oem batteries.

I purchased these replacement batteries for my aging drill/flashlight combo and was very pleased to have them restored to as new with their new power source. These fit a bit more snugly than the originals battery packs but it's not a problem. Thanks for an affordable replacement!

The original batteries and the VTech's replacements both started going bad after only a few weeks and barely able to hold their charge for a long teleconference call.  But these last for hours the way a proper phone should.  Tight squeeze though. And it won't fit into the older version so make sure you get the correct kind!

They properly replaced all three of my at&t phone batteries.  Just almost 2 months in and no issues so far.
I don't have high expectations but hope they'll last more than 2 years.  Good replacements so far to get my phones all back up and running =)

This is definitely a cheaper alternative than replacing all those cordless phones.

I agree with the other reviewers that these batteries are as good or better than the original. They fit better and lock in place more positively(maybe that's due to the old batteries being worn), and hold a charge  for a very long time. I have three of the paslode nail guns so I was very pleased to find these at half the price of the originals.

Love these batteries as a cost friendly alternative to the original Canon. I always buy a couple extra when I get a new camera (since canon insists on changing the battery pack with each new model). Charges fine in the canon charger, battery life is pretty close to comparable to the original.

A much less expensive alternative to the OEM battery.  So far I'd have to say I'm very pleased with my purchase.

These batteries are just as good as the ones with the product name that you are replacing and about 1/3 the price.  Thanks for a really good product.

Great replacement batteries. They are smaller than the original but have more charge capacity and it was much cheaper than buying a new set of cordless phones

I purchased these batteries as a replacement for my VTECH home cordless phone. I actually only needed 1 battery, but for the price it would be foolish not to purchase this and receive 3 of them! Additionally, the mAh rating on these batteries (800mAh) is considerably higher than the original battery, so you are getting a longer lasting battery for an excellent price. So for the replacement unit has performed very well, giving excellent life. Perfect fit in the phone.

A much more economical alternative to buying direct from the OEM. This is not the first set of Wasabi replacement batteries I've bought, and it won't be the last.

The battery works well works fine and last as long as the original batteries they replaced.

I bought 4 of these as replacements batteries for my Tripp Lite UPS I purchased from Costco over the past several years.  As other reviewers have noted (thanks for the heads-up!), some of these units clearly were not made for easy user replacement of the battery.  Two of mine were of this vintage.  Thanks to the warnings from other reviewers, I took note of the positioning of everything as I disassembled and they went back together pretty easily.  My other two units were, I guess, more recent purchases and the battery replacement couldn't have been more straightforward.  So far, the batteries are working just fine.  Time will tell...

I agreed completely with everything "R. Chase" said about these.
These appear to be the best alternative to the Olympus battery and have worked perfectly for me.
As he noted these weigh almost as much as the Olympus batteries. Other aftermarket batteries I have tried are much lighter and, of course, do not last nearly as long.

Was a little leary at first ordering these batteries and not factory replacements.  Was pleasently surprised when the batteries charged up and performed just like the originals. Have used them several times and have had no issues.

After replacing the batteries in my Uniden phone with these and fully charging them for a few days I kept the phone off the cradle to see how long the batteries would last with normal usage. They last a week or more before needing a recharge. My old batteries would barely last a day. These batteries are the ones to get and look and act just like the batteries that came with my Uniden phone.
