Pros: Sale price, quality, and performance.

Cons: None here

Overall Review: At this time the Fujitsu rechargeable AA batteries are the best to be had without having to worry whether or not you may get a sub quality batch from China like Panasonic does with Eneloop. Since Fujitsu is in control of the factory that made eneloops even the good Japan made eneloops are technically these Fujitsu batteries.

Pros: Last a good long time on a charge Rechargeable Lifespan should be over a year even if charged everyday Heavy, but you know it has to be good

Cons: Price is a bit expensive, wait for a sale Heavy Charge time is a bit longer than the lower Mah batteries (mine take about 2 hours or so from a 'mostly' drained state)

Overall Review: I bought a set of these mainly for use in a motorola Xtn series walkie. With a good set of Duracells the walkie would last about a 40 hour work week with shutting off during lunch/breaks. These last just as long if not longer (truthfully after the work week they aren't fully drained but I take them home to recharge anyway). As a comparison: with a set of 1350Mah Rayovac rechargeables I only got a days worth of use on the motorola. I use the smart charger that came with my rayovacs and it seems to charge them just fine, time will tell about longevity. I will buy these again even if just to have spares.

Pros: An energy level above the rest

Cons: A little on the expensive side.

Overall Review: After refreshing them in a my bc700 La Crosse charger, these batteries keep performing where my other 2300mAh ones couldn't match. With the Fujitsu High Capacity, my camera (with flash on) has super fast cycle time and the battery level indicator reads full way past expectations. I truly recommend these for hgh drain useage. Otherwise the standard white Fujitsu 1900+ mAh ones (which I highly recommend also) will do the job nicely in LOWER drain devices as remotes, clocks, radios, etc. Whatever your reason, BUY FUJITSU (Made in Japan).

Pros: Best NiMH batteries made. Made in Japan. Very well made. Reliable. Actual capacity is true to stated capacity. High performance cells best for high drain devices. Withstands extremes in environmental temperatures while in use.

Cons: May not fit some devices due to High Capacity cells being larger in diameter than standard cells if battery compartment is "tight".

Overall Review: Best used in High Drain devices. Use of a good charger/analyser is HIGHLY recommended for best performance, and longest life of rechargeable cells. Cheap "time" based "quick" chargers will rapidly degrade, and destroy rechargeable cells.

Pros: Much Brighter than other brands Ni-MH batterries when I use with flash lights and led lights~!!! Stay longer than the others...

Cons: none so far~

Pros: -Longest lasting compared to any other rechargeable AA.-Rated capacity is accurate. I have an OPUS charger and it has a function to drain the cells and recharge. After a drain/charge cycle, the charger showed that all four batteries took over 2500mAh from the charger. (and this is after 3 years of use!!!)

Cons: -none

Overall Review: -Highly recommend to anyone looking at rechargeable AA's.-Would definitely purchase again and will if they ever come back in stock.

Pros: Not that I can think of

Cons: This battery I got based on the reviews and capacity but whenever I use this during an event with speedlight, after 4-5 shots they heat up and next one flash do not get fire. On the other end if use Panasonic BK-3HCCA4BA eneloop pro AA High Capacity then that never had any issue. Something is wrong with this product.

Pros: I had 8 before. I bought 4 (16 x AA) again from Newegg. I will have 24 x AA batteries. Best NiMH batteries in the world! Work perfect with my powerful high drain flashlight name is EA81 Nitecore that is where I bought from Am---n for about 101 dollars. Insane powerful AA flashlight in the world. I'm very happy with them! But I know AA batteries for flashlight can do reach to about 4,000 Lumens to throw more powerful light like mini sun light! But my EA81 Nitecore flashlight have light drive system strict limited to 2150 lumens. LED name is CREE XHP50 have output 2546 lumens. I will buy more powerful flashlight (don't matter what brand name) which use 12 x AA or 16 x AA batteries and have CREE LED light name is XLamp XHP 70.2 have more bright twice than my EA81 Nitecore and longer run time (must have more batteries to run more longer run times! LOL! :-D). That XLamp XHP 70.2 LED use 4292 lumens! I found info on cree website have fact about lumens on there. You can look up on cree website and you will interest in them! :-) I not interest in buy 18650 batteries, because I'm very scared that something can explode on me! I look up on internet and it's really very dangerous kind of batteries are Li-ion and Lithium are easy to catch fire then explode and can kill us. Avoid them! I have many Duracell NiMH rechargeable batteries (all are made in Japan) that never leak and never explode for many years like about 5 - 8 years old and still never dead yet. They are still strong batteries! I know that is very safe batteries in the world than all other kind of dangerous batteries. :-)

Cons: 500 cycles are short and very cheap. I wish battery companies need to advance NiMH batteries to make more powerful and voltage need to boost to 1.6 voltage similar to standard alkaline batteries. I will call super NIMH to have 1.6 voltage instead of 1.2 voltages. Soon next generation of NiMH batteries will rechargeable 1 to 2 millions cycle times due to new technology like solid state batteries will replace all old batteries in near future. It will reduce a lot of waste to very few (example like fault cells or defect and other issues). I'm tired of cheap alkaline and throw out all of times in trash end up in landfill. All battery companies must phase out support or stop produce on all alkaline batteries to replace to NiMH or other types of batteries which are more powerful and more afford to save money and reduce a lot of waste from them.
