5.0 out of 5 stars BC-700/900/1000 FAQ August 30, 2007
[Update on April 4, 2012]
My original review was written back in August 2007. Now, nearly 5 years later, most of its content is no longer current. So I will use this spot for publishing my "Frequently Asked Questions" relating to BC-700/900/1000 family of chargers. This list is work in progress and will grow with time. Let me know if you have new questions to be added. Here goes...

[Q1] There are four operation modes on the BC-700 (Charge, Discharge, Test and Refresh). Which mode should I use and when?
[A] Most of the time you just need CHARGE mode. That means put in the batteries and select the charging current desired (500/700mA, etc)
- If you want to know how much capacity your batteries can actually hold, use the CHARGE/TEST function. Be careful not to run this operation if the batteries are freshly charged (doing so may lead to over-charging).
- If you want to find out the remaining charge in a battery, run DISCHARGE/REFRESH and record the 'mAh' number at the end of the first discharge.
- If you suspect your batteries suffer from reduced capacity, run the DISCHARGE/REFRESH operation. Or you can use this mode to refresh your batteries once every 6 months or so. Don't over do it!

[Q2] Why won't the MODE button response when I press it?
[A] Press and hold the MODE button for 3 seconds, then toggle it to change mode.

[Q3] What is the difference between TEST and REFRESH?
[A] TEST starts with a full recharge, then it discharges the cell once to determine its capacity. Next it recharges the cell to full again.
REFRESH starts with a discharge to determine the cell's remaining charge capacity, then it charges the cells back up and drain it down again to determine its new capacity.

5.0 out of 5 stars Best charger I ever owned April 28, 2008
Amazon Verified Purchase
UPDATE: (08-12-2012) It has been 5 years since I wrote this review. This charger is still working great!

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, the BC700 can only go up to 700mA (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 for the batteries.

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
- Multi-volt up to 240v. Very useful if you travel a lot to other countries.

Cons:

Now I have to stop myself doing impulse buying on NiMh's because I enjoy using this charger too much.

1.0 out of 5 stars 700 vs WizardOne March 10, 2010
Amazon Verified Purchase
I own both the Lacrosse BC-700 and the Maha WizardOne chargers. The Wizard is larger and it spaces the batteries nicely for cooling and the lighted display, very bright and large, is all-informative. I don't mind that the display toggles between cells, rather than displaying the information on all cells at once. This is my main at-home charger. I keep the Lacrosse at work. More compact in size, the Lacrosse's unlit LCD display is also smaller than the Wizard's but it also is very informative. The BC-700 charges at 200, 500 and 700 Ma, while the Wizard can charge much faster if needed. Frankly, most of the time, I charge at a low 200 Ma on either the Lacrosse or the Wizard for the benefit of longer battery life. The Lacrosse is cheaper and a little more compact, but if you need faster charging (higher than 700 Ma) then the Wizard will fill the bill.

October 2010 update: The Lacrosse now has developed a bad habit of undercharging batteries placed in charger bay #4. Even though the display indicates that all the batteries are fully charged, if one toggles to the accumulated charge screen, it shows that the battery in bay #4 is only half-charged. Sure enough, when I charge that battery again, it will take another half charge to fill it. I now have to do this each time I charge batteries--always have to replace the fourth battery in another bay and continue to charge it for about 6 more hours. This works, but is very frustrating. I would not purchase the Lacrosse again.

December 2010 update: The Lacrosse 700 now is totally unreliable. Several charging bays are indicating full prematurely. I now put batteries back in and watch the 700 continue to charge for hours after it initially displayed "full." Even then I can't trust its readings.

Best charge mode for new batteries?
Run a TEST (Charge/Discharge/Charge) operation on your new batteries, using 700mA charging current.

- If the capacity is significantly lower, run them through the REFRESH operation, at... Read more

Why is there no "battery status" function?
That's like driving up to a gas station and expecting the pump to know how many gallons your tank holds. All it and the charger know is how much it's just put in.

Charging AAA Batteries
There are two negative contacts for each slot of the charger. Align the negative terminal (flat end) of your battery with the inner/smaller contact, then press down the positive terminal.
