    Simple, elegant design.

    • Written by from Limestone

    Looking at the pictures, I thought this item would be rather bulky--like an iPod adapter brick...but it's not, it's probably the size of 4 AA batteries together. A single indicator on top informs of charging status, and getting 6 NiMH batteries is a great deal. 10 year life span according to Apple? Wow. I'll check back in 2020.

    I like that Apple has used the same battery compartment style that is in the Magic Mouse (and maybe other products). Two chrome rivets as opposed to springs. Makes for cleaner install and also like the fact that both batteries install the same way.

    You can hook directly to a 2-prong Mac cord, or use the flip plug like on other Apple adapters.

    I was a little reserved at first, but I'm happy with the $30 that I spent. The batteries look cool, too. :) Although a AAA option would have been a nice touch--but Apple obviously designed this to work with it's wireless accessories - to add a 'green' option to all the batteries that you will be using.

    Neat little charger

    • Written by from NEW YORK

    Neat little charger. Very compact (small enough to fit into a quad outlet with all the other outlets in use!), but has a very substantial feel. Great travel size... the AC plug slides out so you can use your charging cord from your Mac or plugs from Apple's Travel Adapter kit if you're traveling outside the US...

    Comes with 6 batteries - wish Apple sold extra batteries for it.

    It's a 2 x AA Ni-MH battery charger

    • Written by from Douglas

    How can a little device like this create so much understanding? It does its job very well and in accordance with Apple's claims.

    -- it charges 2 cells at a time.

    Apple's description and pictures make this clear.

    -- the indicated charge in Apple's mouse preferences will not show 100%.

    This is nothing to do with the charger but with the battery chemistry. Non-rechargeable (or primary) batteries when new have a voltage of 1.5 V. Rechargeable Ni-MH batteries have a fully-charged voltage of 1.2 V, which is around 80% of 1.5. The "missing charge" hasn't gone anywhere as it was never there in the first place. Perhaps Apple should change the Preferences display to show voltage.

    So, the good points:

    It is very compact and sits quite happily in a standard power distribution strip (at least with UK plugs).

    It has a clear, simple indication of the charging state.

    Low current draw and effective charge management mean you can leave 2 batteries permanently on charge ready for swapping in.

    The 6 cells supplied are targeted at the current wireless keyboard and mouse - 2 cells in each device and 2 on charge ready to swap.

    I have yet to find out how long the cells will last. I get the impression that the charger implements a charging rate that will give the cells a long life. Rapid chargers can reduce the lifespan of Ni-MH cells.

    The only thing I thought could be better was the UK cost - so 4 stars.

    Good little unit. Does everything you expect it too.

    Unlike others I expected it to charge 2 batteries at a time. A little look at the picture would have shown this.

    Charges batteries faster than I need them and that's all I can ask. No reason to grumble.

    Recharge Batteries and Regular Batteries not the same

    • Written by from Mayer

    Most of the reviews I read all seem to say they don't get a full charge, but you are. Rechargeable AA batteries have 1.2 Volts and Regular AA's have 1.5 Volts. That is why they never will show a full charge on the meter.

    Great charger, don't expect greatness from batteries

    • Written by from Lexington

    First, the charger itself is awesome. It's small, simple, and easy to use. That's about all I need to say about it.

    Otherwise, be careful about how you read into battery charge percentages. I have not had any flashing amber lights yet, but I did notice that even after a "full" charge, the batteries only registered around 85% as seen in the bluetooth menu. At first I thought they might actually not be charging correctly, but I have a different theory now. As it is impossible to instantaneously measure the actual capacity of a battery, I think this phenomenon is simply caused by the fact that rechargeable NiMH batteries generally have lower capacity and run at slightly lower voltages than single-use alkaline cells (due to their chemistry and some other factors). Apple's NiMH cells say they are rated at 1900 mAh, while standard Energizer or Duracell alkaline cells are typically at least 2300 mAh. Thus, if Apple decided that 1.8V is 100% charge and 1.3V is empty, and at full capacity their NiMH cells only reach 1.7V, that would easily explain the lower percentage readings. So... I would say don't worry if you see these percentages, but don't expect these batteries to last quite as long as normal alkaline cells per charge either. I am not complaining, because I'll hopefully still be saving money over time.

    Let them charge long enough

    • Written by from Mobile

    Several people said they only got them to 80-85% charge before placing in the trackpad. I saw the same thing, but I let them charge past green, until the light fully shut off. Placed them back in Magic TrackPad and they were 100%. They are evidently still trickle-charging with the green light. Hey people, don't be too quick to criticize. Investigate and give things a chance to work.

    Label batteries in pairs

    • Written by from Webster

    Love this product. I use them for the wireless keyboard, trackpad. I bought another set to use for my Nikon SB-900 camera flash unit. They're amazing for that application.

    Labeling batteries in pairs will make them last longer, as they will have the same amount and relative number of charges and use cycles.

    Nothing wrong with 85% charge...the batts are OK.

    • Written by from Cupertino

    The battery level display for the Bluetooth devices is calculated based on the battery voltage. While AA Alkaline batteries have a 1.5 Volt nominal voltage, rechargable batteries have a maximum voltage of 1.2 to 1.25 Volt. That's about 15% less - hence the 85% charge people reported seeing with fully charged batteries - perfectly normal for rechargables. Save the trip back to the store.

    Great Little Charger

    • Written by from Oro Valley

    Nice & compact. Easy to travel with. First time I tried to charge the batteries, I got a blinking amber light indicating a problem with the batteries. Unplugged it from the wall and plugged it back in and worked fine after that. So far, no issues.

    NOTE: Due to the nature of rechargeable batteries, they will NOT show 100% charge on your Mac. Alkaline batteries put out 1.5 volts, while rechargeable NiMH batteries are rated at about 1.25 volts. This means a fully charged battery will only display around 83%. Do not be concerned if Mac does not show 100% charge for your mouse or keyboard. This is normal.

    cool little charger

    • Written by from Warner Robins

    I go way back with rechargeable batteries and have had mixed results with them. One thing i have learned is that they "remember everything" and you only get one chance to abuse them. With that i mean don't discharge them fully or they may reverse polarity, don't short circuit put them in some device which draws more current than they are designed for and under no circumstances leave them on charge forever because while the manufacturers intend this practice to "maintain" charge, what it in the ends up doing is shortening the lifespan. A rechargeable NMH or Li will show aslight "peak" in voltage just prior to (under a given discharge rate) it's beginning to fall off, for the most part this occurs around 30% or .8VDC (assuming a 1.25V cell) if you plot the terminal voltage verses remaining charge current. What this means is that if you recharge these little things whenever convenient, somewhere between 25 and 35% ond only until the indicator has chaged from amber to green (don't wait for it to turn off) these should last for many, many, many cycles. I hope this helps.

    Of course rechargeable batteries don't read 100%

    • Written by from Arlington

    Devices measure available charge by voltage, and NiMH (or NiCd or Li-ion) rechargeables *never* reach as high a voltage as traditional alkalines. It's a question of chemistry. HOWEVER, the rechargeables also stay at usable voltage longer, delivering their rated capacity. So if your mouse reads 80%, it's because it's calibrated to the old-fashioned, environmently damaging disposable batteries. In terms of economics, you will break after perhaps a dozen charges even though "disposables" are cheap. Apple should be faulted if it doesn't make it clear, but they're not ripping you off. We have been using rechargeables in a Mac wireless keyboard and mouse for years. The key is to have a fresh set always ready to go.

    Apple should be faulted for not pushing rechargeables long ago. It's the thing to do, to save money, your sanity, and the environment.

    The batteries are Sanyo Eneloop with Apple branding. They are the best ...

    • Written by from Montgomery

    The batteries are said to be a version of Sanyo Eneloop with Apple branding. They are the best rechargeable batteries made. They don't deplete in storage the way standard rechargeable batteries do. I'm not keeping close track of how often I have to change batteries in my keyboard and mouse but it is not very often and it is a simple thing to just exchange two from the device with the two standing by in the charger. Better for the environment, right? Even if they don't last as long as alkaline's in the long run much less waste and less cost too.

    Have multiple computers and need more batteries? Just get a set of Sanyo Eneloop AA's and you should be able to use the Apple charger. (Apple does not sell batteries separate from the charger).

    Another great Apple product!

    • Written by from Stockton

    I have read all of the reviews to date and after using the charger and batteries felt that I should write this review. I did have a little difficulty with the charger at first until I realized that the ports on the positive contacts of the charger had a very close tolerance and the batteries were a little bit of a tight fit. So when I inserted the batteries and applied a little pressure to seat the positive end of the battery into the charger the batteries charged fine. I think that the ports on the positive terminals of the charger will loosen up after some use. As far as the fully charged batteries registering approximately 80% on the wireless mouse or keyboard... The voltage of a fresh AA alkaline battery is approximately 1.5V. A fully charged AA NiMH battery has a voltage of approximately 1.2V. The wireless mouse and keyboard are probably configured to register 1.5V as 100%. If you do the math the AA NiMH battery should register approximately 80% when fully charged and inserted into the wireless mouse or wirless keyboard. I hope this helps!

    Comes with 6 rechargeable batteries (so 2 in your Magic Mouse, 2 in your Wireless Keyboard and 2 on charge).

    The description says the batteries are delivered fully charged, but still took 5 hours on charge out of the box until they went 'green' - when put in my Magic Mouse the charge level was 88%, but this is due to them puffing out 1.2v instead of 1.5v.

    Rechargeables always give out 1.2v so perhaps Apple should change the indicator, but other than that they're fine.

    Excellent Product

    • Written by from Edna Bay

    I feel that the Apple Battery Charger and battery kit is an excellent product for the price.

    The unit is compact, compatible with other Apple AC adapter extension cables, and charges very quickly. All 6 batteries arrived with %80+ charge on them, and only took about 30-45 minutes to top off. So far the battery life is outstanding. I've been using my devices on the batteries for almost two weeks, for about 12-16 hours per day and the battery reading on my Magic Mouse is %65. So at that rate, I should get over a month between charges. That's well beyond acceptable to me. Add to that the number of charges these batteries will take, and you have an economical, and environmentally conscious product that is hard to turn down.

    I love the design of the charger, and the LED indicator. I also like the low vampire draw design that keeps even the charging LED from staying on forever after it has fully charged the batteries.

    Another excellent product that goes well with the range of wireless Apple products. I felt very pleased that Apple chose to include enough batteries to power the wireless Magic Trackpad, Magic Mouse and Apple Wireless Keyboard in one package.

    Thank you Apple!

    Disappointing product

    Quirky charger, batteries that discharge when just sitting idle. I bought three sets and all of the chargers are not working anymore. The yellow light keeps flashing.
