POWEREX MH-4AA270-BH 2700mAh 4-Pack AA NiMH Rechargeable Batteries (Made in Japan) w/Carrying Case

Pros: I use them in my mustache and beard trimmer. Great Rechargeable Batteries

Cons: none

Pros: Powers toothbrush, remote, toys, keyboards and mice, and anything else I put them in. Will power digital cameras for quite a while.

Cons: None

Other Thoughts: Need to get some triple A

Pros: High current rating, long lasting

Cons: none

Other Thoughts: Initial cost for batteries with good charger are a bit steep, but savings over disposable batteries more than make up for it. I've got six year old kid with lots of battery operated toys, these are perfect for them. Have tried a few other name brand rechargeables, they can't compete with these. Currently own around 20 of these, the oldest are more than year old and still working well

Pros: high capacity. I use them with my flashlight NIKON SB600. easy can take 500-600 pictures with single charge.

Cons: none

Pros: This is my third set of these Powerex batteries (16 total, now), and they outlast, outperform anything on the market as far as charge capacity and charge retention. I can charge these up today, drop them in a bag and they will have 85-90% charge after 3-4 months in storage. They last as long as Alkaline batteries (usually longer) in my cameras, flashes, and other high-drain devices.

Cons: None

Other Thoughts: I charge mine in a Powerex C9000, programmable charger that I picked up locally (with my first set of batteries), although any quality charger will do (even the cheap, Energizer brand ones from Wal-Mart... you just have to prevent over-charging if using a cheap charger, and make sure it can handle at least 3-amps.

Pros: Amazing in my digital camera, they really last longer than any of the best name brands available in any store.

Cons: NONE

Other Thoughts: I have bought these several times for myself, parents cameras, kids toys only because they are truly amazing! And even though I always post dozens of helpful reviews...

Newegg fails to acknowledge any of them because they omitted all of my reviews from the current contest... where ever I used the word amazing ?

Pros: they hold a huge charge and hold a charge for along time

Cons: no cons i can see

Pros: I have been using 12 of these now for my Nikon SB-600 Flash unit for quite a while now and they are fantastic. They give me a quick refresh rate for full power and almost constant instant flash for 1/4 power or less. The SB-600 (as well as most high end TTL Shoe mount flashes) eat batteries like nothing you have ever seen. Its stupid to not use these batteries. make sure you have a good MAHA charger.

Cons: On super quick discharge I have noticed they get fairly hot, but that's to be expected. They drain a bit over time when not in use, but nothing 10 min in a charger can't fix.

Other Thoughts: I have used these in a LED flashlight too with very good results.

Pros: Worked well why they lasted. Carrying case was a plus.

Cons: Didn't recharge as many times as the Canon batteries I bought with my Powershot A80. I continued using the Canon batteries when I upgraded to an A100IS. When they finally gave out after years of use, I purchased the Powerex batteries. After just over a year the Powerex batteries don't hold a charge. I just placed an order for Canon batteries.

Pros: High discharge battery for frequent use items.

Cons: They ain't cheap, but they are quality.

Other Thoughts: For best results, use a high quality charger (like Maha).

These Maha Powerex batteries are for items you recharge batteries for daily or weekly. These are not the type of battery you can let sit for 6 months or a year.

Buy the Low Discharge Maha Imedion (or eneloop style) for TV remotes, clocks, emergency flashlight type items.

For some devices/users this is simply the best battery choice. That is a fairly narrow market, however. The majority of users could buy a Low Discharge NiMH battery that functions better for their needs at a lower price.

The batteries work better than any battery I have used in a couple of devices. In those devices this is the only battery I will use. In the majority of my other devices I use less expensive Low Discharge batteries (always ones made in Japan)
