5 out of 5 eggsExcellent Charger

Pros: Versatile charger, tracks and charges batteries individually, high capacity (8-AA). Will "slow" charge, rapid charge, or "cycle" batteries. One of the best investments I have made, no more disposing of AA batteries.

Cons: None so far.

5 out of 5 eggsAwesome battery charger

Pros: This battery charger has been perfect, charges relatively fast even on "soft" mode and the battery reconditioning mode helped get back the battery life of a few of my older batteries.

Cons: No backlit LCD, but I already knew this when I purchased it.

2 out of 5 eggsMH-C800S Charger Review

Pros: When it worked, it charged the batteries well.

Cons: The screen is dim and hard to read.

Other Thoughts: I used this sparingly (charged approx 2 AAs each month) for 11 months. During this time the charger worked well. However, after about 11 months I plugged a battery in and it wouldn't recognize it. I disconnected the power, let is sit for a while, and then plugged the charger power back in without any batteries installed and was disappointed to see "done" flashing for each battery location (despite no batteries being installed). I called Powerex's tech support and the guy told me that the charger needs to be replaced. Luckily, it has a 3 year warranty so I just had to pay for return shipping...but I'm hoping this isn't a sign of how unreliable the charger will be.

2 out of 5 eggsnot so good

Pros: It has 8 circuts for 8 different batteries at once.

Cons: Maybe mine is bad but it is extremely picky about what batteries it will charge. Most of my batteries and 3 of the 4 AAs that came with it as a gift it won't charge consistantly. All of these batteries seem to work fine in my department store generic charger.

Other Thoughts: The display is worthless. It is so dim I cant read it. The should stop giving away useless junk with this charger and just lower the cost.

5 out of 5 eggsBEST CHARGER for AA batteries

Pros: My family now owns 3 of these chargers. They are the best chargers we've ever owned for AA batteries.

The ability to properly charge each individual battery has made them last longer (battery life, number of recharges).

Cons: Not really a con, but I wished the power connector on the charge tray was L-shaped instead of straight.

Other Thoughts: We now always have a quick way to recharge the AA batteries used in our Wii controllers, 2-way radios, camera flashes, etc. LOVE IT.

1 out of 5 eggsGood While it Worked

5 out of 5 eggsGood quick charger

Pros: 8 charging slots, quick, works as avertised

Cons: Cells can become hot during charging - especially AAA

Other Thoughts: This charger has worked out really well and it is great to be able to charge 8 cells simultaneously. The refresh function is great for AAs and the soft refresh works well for AAAs. To access the soft refresh function you simply place the first cell and press both buttons at the same time.

5 out of 5 eggsGreat charger for heavy usage

Pros: We use 2x this charger at my work to charge 16 AA Sanyo batteries at a time. We use the batteries in wireless lapel mics for 1-3 hour classes. We then charge the batteries. This happens at least 2-3 times per day. These chargers have held up to this usage for the last 6 months without issues.

Cons: Nothing major, just wish the screen was easier to read. Or there were led's to indicate finished or charging so I could see if the batteries were done from across the room. But the included screen gives a great amount of information.

4 out of 5 eggsWorks well for me

Pros: Charges batteries one at a time. Multiple charging functions, including a fast charge. Easy to understand display.

Cons: Display not backlit.

Other Thoughts: This is a great charger for the prices. Great for charging AA and AAA batteries to keep up with the kids toys, especially the AAA for GeoTrax. The conditioning mode is great, it brought some batteries back to live. The display is not backlit, but I don't find that a big deal.
