Product Description
The La Crosse Technology BC700-CBP battery charger works with all NiCd and NiMH AA and AAA rechargeable batteries and can actually increase the power capacity of some older rechargeable batteries. Choose the Discharge Mode to completely discharge the batteries energy and then recharge it to full capacity in one cycle. The Refresh Mode restores the maximum capacity of your batteries by utilizing a 20 cycle discharge and charge mode. The BC700 also offers a Test Mode that determines the true capacity of your batteries. Includes power adapter.

 If only it would hold AAA batteries properly November 27, 2009

The charger worked fine except for one serious flaw: AAA batteries consistently popped out slightly and would no longer charge. The batteries need to be seated firmly in the charger and the shorter AAA batteries use a separate clip for the positive (+) terminal. That clip doesn't push back hard enough to keep the battery in place. The battery needs to only ever-so-slightly out of place to no longer charge. With all the positive reviews, I think most others have not had this problem, but it rendered it useless (and returned) for me.
 Nice idea, wretched QC November 26, 2009

A couple of years ago I ordered a BC-900. It was DOA from Amazon, with a completely nonfunctional keypad, and I returned it for a full refund. Eight months ago, naively presuming LaCrosse had improved the reliability of the newer BC-700, I ordered one. It worked. Yesterday the keypad quit working, despite moderate use in a very clean environment. Tomorrow I will be taking the charger apart to try and fix whatever has failed. It's not worth paying to ship this thing back to the maker for warranty repair. If it is unrepairable, then straight into the trash it goes, along with my opinion of LaCrosse products' quality.
 NICE CHARGER! November 24, 2009

Hi,
First I was a little scared to buy this costlier charger. And, costlier because i was used to other $5-$10 chargers and my eneloop USB charger's cable broke so i needed one. After reading reviews about this one and bc900 and finding that I am not going to use features of bc900, I decided to buy this one and it is really doing its job. I am using it for past 1 month and I haven't had any issues with burning or over heating. I have charged my energizers (2500) in discharge/refresh cycle and they got charged in 5 days. but they lose their charge really fast. I have eneloop 6 batteries which I charged with Test mode and they are working even better. They retain charge for long time so I am happy with charger and my personal eneloop batteries.
I'd recommend this charger to anyone with enelopp battries, It's very easy to get started and it comes with instructions which are pretty clear. Thanks to Lacrosse.

It's a good product with great features. I would recommend getting the better BC-9000(with BC-9009 charger & batteries) if you can get for it $40 or less.
You have to be smarter than the BC-700 to use it effectively. It's easy to overcharge certain batteries(ie. Duracell AA or RayoVac AAA) if you leave it on default charge rate of 200mA. Most La Crosse chargers and some similar chargers are not able to terminate (or stop charging) with low charge rates and will overcharge certain batteries. So you need to monitor the mAh(capacity)Display and/or Total charging time with new batteries or those that have known issues with overcharging at low charge rates. Even though you can set it to the its highest charge rate of 700mA to help it terminate properly, you'll need to a press 2 buttons a couple of times within the 8 sec time window.
FYI, if you overcharge your batteries, you will shorten its life or even ruin them permanently.
Most Battery manufacturers recommend between .5C to 1C for the preferred charging rate. Setting it to 500mA takes 1-2 steps. The 500mA charge rate is above .5C for most AAA batteries.
Let's say that you're charging four 2000mAh AA batteries. Using the max charge rate of 700mA, you will be charging at .35C(Or 35% of the batteries' 2000mAh Capacity). If you use a BC-9009 or BC-900, you can charge at 1000mA which is .5C or 50% of max capacity. That's more likely for the charger to terminate the charging process for each 2000mAh battery.
Pros:
+Nice LCD Display
+Sophisticated Charger that Refreshes your older batteries.
+Individual Circuits for each battery.
+Price is right when you get it for $25 or less.
Cons:
-Need 1000mA Max charge rate since most new AA's are a least 2000mA. Charging at 1000mA will alleviate overcharging issues.
-Not Non-Techie friendly, [Wish they gave a video tutorial.]
-No Fail-Safe for Overcharging. Want the ability set Max mAh Allowed. (ie. to the max capacity of your highest battery) For AA's I would set to 2600. My BC-700 allows charging over the 3000mAh Capacity even though you're not supposed to use 3000mAh batteries.
-Needs an easy option to jump start really weak batteries which end up displaying "null."
-You can't change to a higher charging rate for additional batteries placed in the empty slots since it restricts the Max Rate to the initial charging rate you set for your first battery. The only way to reset the mA charging limit is to remove all the batteries or unplug the charger.
If the BC-700 had defaulted to the 500mA charge rate instead of 200mA, I would have given it 4 stars.
Plus if it had the Max Charge Rate of 1000mA, I would've given it 5 stars.
I hope La Crosse will make updated models with a toggle switch to set higher default rates.
