I ordered this charger to replace an older one. I have used several different charges on the same phone.  Once a non-replaceable phone battery is more than a year old I notice it doesn't hold a charge as well as it did when it was new. It's like that with cordless home phones as well. Rechargeable batteries need to be replaced at least once a year. On phones where the battery cannot be replaced that's basically the problem.

Update: cell phone batteries can be replaced. There are cell phone repair places that will replace rechargeable batteries for a reasonable price. I had my battery replaced and now use this charger. Works like a charm. Could not be more happy!

The reason to buy rechargeable batteries is so you can charge them and then play Xbox.  These batteries do not hold a charge.  As soon as you unplug the batteries they immediately die, which completely defeats the point of them.

I have acquired several of these batteries over time and, (in my opinion) will be saving money in the long run. So far, they have been holding up really well. I have several items that require AA batteries, and they do eventually run down. I keep at least 16 charged at all times. I chose the energizer because of use in the past. I suppose there may be others to claim they are better, but for me, I'll stay with these. Thanks.

Very convenient. Now I don't have to waste money on batteries. Thanks a lot!

My son told me about this item as I have had variable results with rechargeable batteries.
Watch for sales, as I did not. However, this works as advertised.

2014 review: In the past, I used to buy those dozen packs of batteries (YES, BOTH AAA/AA) from Costco or Walmart. Usually for xbox controller batteries, portable radio walk-men, etc. Although lately I'm sick of wasting a lot of money into buying them......that I might as well try this product out.

2017 review update: I thought I would dispose this product already, but I still have this with more rechargeable batteries charging once a week. This product is perhaps the best batteries I ever spend on. Haha, the reason I put this as a 4 star is because it takes 3-3.5 hours to charge my batteries completely. Luckily I charge them a day before taking them for camping, night riding for 30 miles out of town (use for "Bell" bike flashlight), and obviously music for my old Walkman.

This is going to save us a ton of money. No more tossing perfectly good batteries or guessing which batteries are good in the drawer.

Great way to save money. Now I don't have purchase batteries every couple years for my lawn and garden equipment or anything that is stored for extended periods.

I go through a lot of throw away batteries. I decided to make a large one-time investment and purchase rechargeable batteries and chargers. I bought this plus extra batteries, a Ray-O-Vac Charger and extra Ray-O-Vac batteries and have no regrets over the purchase. The charger and batteries work as advertised and arrived promptly. As advertised, batteries arrive charged and they hold their charge well while waiting to be put to use. They charge quickly and can charge in any charger, not just the Duracell one. The charger has a small red light on front that lights up when charging and shuts off when the batteries are charged. There is no cord; the plug is built into the unit and folds out for use. I'd say it takes about 6 to 8 hours for the batteries to charge. A great investment I will use over and over again. This is a product I can recommend without hesitation.

{This is an update. After three months, these batteries started losing their charge faster. Within a short period of time, they no longer held more than three hours. So I changed my review to three starts instead of five.}

These batteries have made my cordless phones like they are new, not like before, with the old batteries. I was only getting an hour of use out of them. If I could, I would give these Panasonic Ni-MH Type 29 (HHR-P104B) batteries more than five stars. My only complaint is, and this is a good thing, I can't seem to use them enough so I can recharge them from dead to life. I am so happy I can use my phone speakers again, even though I've used them for days.

The price was exceptional for them as I checked with a battery store here, and they wanted $17.95 for one! Getting two for the price of one was cream cheese icing on the dark chocolate cake. (One of my favorite desserts.)

They came right on time, within a week. So my phones were up and running after the 24 hour charge time recommended by the seller.

I have recommended them to my friends and family so they can save money and have batteries that meet more than their expectations. If you want batteries that will last a long long time, and not have to pay an exorbitant cost for them, buy these. You can't go wrong.

Initial review is below.  After reading the review the seller contacted me and offered to make good via shipping a new unit or taking $5.00 off my credit card to compensate me for the new batteries I'd had to buy.  I elected the $5.00 as I had, indeed, already bought new rechargeable batteries and a charger.  I'm satisfied with their response to my uncomplimentary review but I stand firm that the manufacturer should be checking the batteries they send with their units to make sure they will work properly.

Right out of the box this thing is defective.  The batteries provided won't take a charge.  Rather than go through the hassle of sending it back I went to Harbor Freight and bought a set of rechargeable batteries and a charger.  I see others have had the same experience I have, i.e., the batteries supplied will not take a charge.  The manufacturer is not, apparently, paying any attention to the reviews.

I am so glad I own this product. This and my rechargeable 9 volt battery have saved me so much money. I like that you can charge two batteries at once, so you can always have back up. Not much more you can say about a battery charger.

I like these solar light detectors because they seem as bright as powered ones, but I am now having to replace the batteries after 4 months now at $10.00 a pop. I bought these in July when the days were long. The old batteries were beyond recharging when I replaced them today,  so I am considering a recharger for the long haul. I am in the Pacific NW so its dark by 5pm. I am going to see how long these second set of batteries last with the short days this fall and winter season, but I already suspect a recharger is a necessary addition (that will pay for itself within a few months) if I am going to use these year round.

I'm usually hesitant to buy off brand batteries because my experience has usually been bad.  It turns out that I'm still too cheap to buy the Sony branded batteries so I took my chances again.  I was not let down this time.  These batteries work really well.  I now have more battery power than shooting time on my flash card so I don't have to stop because I'm out of power.  A 2-pack with a charger for less than you would spend on one single Sony battery - what a deal!

Batteries are always something we need. I can never have enough batteries. I normally don't buy rechargeable but it makes sense that they would be very useful. Buying regular batteries is very wasteful. And let's face it they can get costly. With a device that drains batteries easily I can easily have to replace batteries once a week. So evidently I run out or have to make sure I'm fully stocked. But the few rechargeable batteries i did try ran out so fast. They didn't last as long as a normal battery and I was replacing/recharging them once a day.  So that was a big pain in the Behind!
I love that these can be recharged up to 500 times when fully or partially drained. Most rechargeable batteries cannot be charged that many time.
The package includes 4 batteries so you will always have spares.
These do last longer than other rechargeable batteries and that is a huge plus. They are also durable in any temperature so I can keep them in the camper or shed and not have to worry about the heat/cold draining or ruining them. They are fit for Flashlight, Headlamps, search light lamp, and other electronic products so they will have lots of use around my house.
I received this product complimentary in exchange for my honest opinion but the opinion expressed is all my own.

works well and saves on batteries. I would have given it five stars except I felt the price was too high
