Best charger I ever owned
I have owned at least 8 chargers in the past, Maha's, Panasonic, etc. It is nice to see that this charger shows you the mAh on the LCD panel as the battery charges up. Most chargers you only see an LED indicator to signal when charging is done.
Compared to the specs of BC-900, BC700 can only go up to 700mAH (the max) which means it is somewhat slower than the BC900. But the faster the battery charges, the hotter it gets. And one of the worst enemy of rechargeable batteries is heat. Less heat means longer life.

Pros:
- 3 adjustable charging speeds
- Will show you the actual capacity in mAh. This is good so you know which battery needs to be refreshed. You always want to use batteries with the same capacities in pair or in a group.
- 4 independent charging stations with individual LED readouts. "AA's" and "AAA's" can be charged in different combinations. Don't you hate those gadgets that only use 3 batteries like portable radios? (walkie-talkies). You end up with 1 un-used battery if you bought a 4-pack. How will you charge it if your charger only charges in pairs?
- Reasonable price for an excellent charger
- Small and light. Better portability

Cons:

Great charger but.......
This is a great charger and when I bought it it was about $15 less than the BC-900. Now the BC-900 is less than this charger. The difference between this charger and the BC-900 is the lack of the faster charging speeds and the accessories. Definitley buy the BC-900 and the accessory package for less money. It seems they are constantly playing games with the pricing on these two chargers. The BC-700 charger does a great job of reconditioning batteries and the charging speed is usually between 2-3 hours for the different capacity batteries that I have. (1800mh - 2650mh). Time is not an issue for me as I have about 10 sets of AA's and can just keep swapping them out. From what i've read the slower charging speed is better for the life span of your battery any way.

Very versatile battery charger
The BC700 battery charger is extremely versatile. You can charge AA and AAA rechargeable batteries at the same time. You can also charge at different speeds. If I need my batteries charged quickly I will set the charger at a higher current but if I have some time, I'll set it to a slower current, which is better for the batteries. This is one of the best, if not the best charger out there for the price.

Handicapped version of BC900
Just in case you were looking for the La Crosse Technology BC-900 AlphaPower Battery Charger: please be advised that ths is NOT the same charger.

Except for the color, the BC700 looks exactly the same as the better-known BC900. However, it is actually a "handicapped" version of the old charger. Its charging current can only go up to 700mA in three steps (200/500/700). The BC900, on the other hand, can go up to 1000mA for 4 cells, or 1800mA for 2 cells. Also the BC900 package includes eight NiMH rechargeable cells (4 AA and 4 AAA), eight C/D cell adaptors, and a carrying case. The BC700 does not come with any bonus items.

This is not to say that the BC700 is a bad product. Quite the contrary, it is better than any other NiMH AA chargers in the market except for BC900 and Maha MH-C9000. If you can find it at a substantial saving (like maybe 30% off from the price of BC900), it is still a good buy. But as it is right now, I recommend getting its older brother instead.
