    Batteries deliver as promised

    • Written by from Saint John

    I was skeptical about trying these batteries after reading some of the reviews posted on here but after receiving them i must say i am quite happy with the results.

    A few reviewers had posted that they would not fully charge in the charger and the batteries would only show a level of 85% on the battery indicator for the magic mouse after charging for several hours. I have a feeling that the reason the battery life indicator is reading less then 100% is a result of NiMH batteries running at 1.2V vs 1.5V for alkaline batteries.

    When i received the batteries i topped up a set in the charger for about an hour, until the green light came on indicating a full charge. I placed them in my Magic Mouse and used them for a solid 8 hr work day and only witnessed a drop from 87% to 86% which is great! The charger is small and fits easily in a packed power bar which is a big plus for me too.

    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.

    Defective Product

    • Written by from Atlanta

    I got this product yesterday and after a full 7 hour charge i could only charge the battery to 85%. I went back to the apple store and got a new replacement. I still have the same problem with the new piece and hence getting ready to return this one tomorrow.

    Works great with apples batteries. Tried Energizer NH15 2500mAh NiMH AA

    The batteries and charger got REAL HOT!!!! after 1hr. Did not charge brought the Energizer NH15 2500mAh NiMH AA back to store.

    Does apple sell extra batteries only?

    79% charge and why only two?

    • Written by from GRAND BLANC

    Just like the other reviews stated, my batteries only charged to 79%.

    Also, why would Apple make it so you can only charge two batteries at a time, my wireless keyboard takes three batteries!

    Six batteries are included so it would have been nice to charge three at a time only having to swap the sets twice.

    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!

    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.

    Don't spend the money! These batteries don't charge!

    • Written by from Hockessin

    I can't get these batteries to charge - the amber light stays on and the green full charge light never comes on. Even overnight charging doesn't seem to work. This is going right back to the local Apple Store for a refund. Save your money - use regular old Alkalline batteries instead.

    Save your money!

    • Written by from Fairfield

    I've been using rechargeable AA batteries in my mouse and keyboard for years (The standard Energizer/Duracell type). They come out of the charger, go right into my mouse /keyboard (at about 84-87% battery charge) and then after about 10 days, they go right back into the charger. It is really rare at my use rate that they last any longer than 10 days. It is a hassle, so I decided to see if Apple's attempt was better than the standard.

    My first batteries came out of the charger (after being charged for 24 hours at only 74% battery power and it took 7 tries to get the new batteries into the charger so they would charge without having the flashing Amber light which says that I either have the wrong or damaged batteries-straight out of the box. Not good!

    Save your money and shipping charge and buy the regular Energizers-they hold a bigger charge.

    Bad Batteries

    • Written by from Boulder

    There appears to be a problem with the batteries, at least for some people. All three sets of batteries included with my order would only charge to between 81-89%, according to my Magic Mouse. When I put in a fresh set of Energizers, it registers 100%. With good batteries this will be a good product.

    All Three Battery Pairs Were Defective

    • Written by from Los Angeles

    I wanted to love this product, but all three sets of batteries flashed amber after charging them, and once installed in my wireless mouse, only registered about 50% capacity. I will return this product to the Apple Store for another, hoping I can change my assessment.

    Great value for a great price.

    • Written by from Bacliff

    It's really nice to see a company come up with something to reduce both landfill contaminates AND consumer cost. I've been looking for a way to have my replaceable battery items to have rechargeable batteries, the only thing holding me back was the initial cost. At $29 on average for a battery charger (without batteries, which depending on brand can be half the cost of the charger for only two), I considered that to be too pricy. I'm not saying the environment isn't worth it, but I'm just a blue collar worker, don't really have the $70+ to get all my devices on rechargeable. Well, thank you Apple Inc. and Mr. Jobs for giving me the opportunity to help the environment without costing me an arm and leg. This is a great product at the price, and with the battery type, I can get more than the initial six it comes with and still not cause my wife to go insane because I'm trying to save our environment and money for the long run.

    A Must Have

    • Written by from Vernon

    This is one of the best accessories that apple has created in a long time. The rechargeable system is a must have with any wireless items. I hate to say that the normal batteries don't last long in my wireless keyboard/mouse/trackpad. I find myself having to change the batteries once every other month or so, and that really adds up to the number of batteries I go through each year. At least with the new rechargeable system, it only takes 5 hours for a full charge, and the batteries have a 10 year warranty.

    Excellent design and simple to use.

    • Written by from Pontiac

    The charging unit is very compact and the charging time seems to be fairly quick. The six batteries that come with the charger is a good amount (for use in Keyboard, Mouse & Track Pad). I am really happy about this purchase and glad that now I don't have to recycle batteries all the time.

    Apple Battery Charger

    • Written by from Federal Way

    I just got mine today! I'm pleased with it so-far; although, I thought it said the batteries would be charged and ready to goI

    So I plugged it in with the two batteries in place as shipped and it gave me a red light. In about an hour it changed to green.

    I'm happy with it!
