La Crosse Technology Alpha Power Battery Charger, BC1000

 

Customer Reviews

I purchased the La Crosse Technology BC1000 Alpha Power Battery Charger, not because I needed another advanced battery charger/analyzer (I already own the La Crosse BC-900, BC-700, BC-500 and the Maha MH-C9000), but because people kept asking me: "Is there any difference between BC-900/9009 and BC-1000?" So here it is, to put the issue to rest...
[Exterior]
Except for the color, the BC-1000 looks and feels EXACTLY the same as my old (circa 2006) BC-900. Even the boxes they came in have identical illustrations on them. Check out the customer images I uploaded to 'Customer Images' section and you'll see what I mean.
[Electrical Spec]
The specifications are EXACTLY the same for both chargers, namely:
- Operations: Charge, Discharge, Charge/Test, Discharge/Refresh
- Charging Current steps for 4 cells: 200mA (default), 500mA, 700mA, 1000mA
- Extra Current steps for 1-2 cells: 1500mA, 1800mA
- Acceptable battery capacity: 300-3000mAh (my previous testing showed the BC-900 can actually charge up to 3700mAh)
[AC Adapter]
Again, the two AC adapters looked identical except for the colors. Both are rated for 100-240V AC input, and 3V 4A output. There is, however, a small difference in their open-circuit output voltages. The BC-900's adapter measures 3.0V, while the one for BC-1000 measures 3.17V
Date code on the back of BC-1000 adapter says '4710', which means 47th week, or November of 2010,
[Firmware Version]
My old BC-900 has firmware version '33'. The new BC-1000 shows '37', which is the same version for BC-9009 sold since middle of 2010.
Note: firmware version is the number briefly displayed in the rightmost column, after you plug in your BC-900 or BC-1000.
[Quirks]
Sadly, the same limitations for BC-900/9009 are carried over to the BC-1000:
- If you put in a completely depleted cell (battery terminal voltage under 0.5V), the charger cannot recognize it and the display says 'null'
- If you were previously charging at 500mA, for example, you cannot subsequently increase the charging current for a new cell to higher than 500mA. You need to remove all cells in order to reset the maximum limit.
If I stopped my comparison right here, I would have concluded that the BC-1000 is nothing more than the BC-900/9009 with a cosmetic update. But wait, there's more to the story...
[Interior]
After I removed the base from my BC-1000 (by the way, don't do this unless you know what you're doing), I was surprised to find a very different printed circuit board inside. There are significantly more components on the BC-1000 board compared to that on the BC-900 (refer to my uploaded picture in 'Customer Images' section):
- The BC-900 has just one 'glop' covering the controller IC
- The BC-1000 has two 'glops' on its PCB, suggesting that there is an extra controller. Given the past history of 'meltdown' problem with BC-9009, the most likely function for this controller is to monitor temperature during charging.
- The BC-1000 also added four bulky thru-hole diodes ('B220' 2A 20V Schottky diode) on the PCB. Again, the most logical explanation is to burn off excessive power during charging, to prevent other surface mount components from over-heating and suffer a thermal runaway.
[Conclusion]
The BC-1000 may look exactly like the older BC-900 and BC-9009 from outside, but there is significant design overhaul that took place inside. Note that I cannot testify that BC-1000 has solved all thermal-related problems, because I have never witnessed any over-heating problem before. But as an engineer, I know that no company will accept a design change that ADDS cost to an existing product - unless it is absolutely required to fix a problem.
Assuming the alleged 'meltdown' problem is really solved, one question still remains: is the BC-1000 a better value than the Maha MH-C9000 (currently available in the same price range)? Personally, I think the user interface of BC-1000 is much better, but other people may disagree. So it comes down to whether you can make use of the bonus items (4xAA + 4xAAA cells, 4xC + 4xD-cell spacers) in this package. If you can use some of them and feel that they are worth paying $10 for, then go for the BC-1000. Otherwise, you may want to consider the BC-700 at half the cost.

I just got this a few months ago, and it's been serving me quite well. It's main advantages are the amount of manual control it gives you and of course its ability to report data on the status of the batteries being charged. It also comes in a travel bag and is paired with plenty of accessories like 4 2600 mAh AA batteries, 4 1000 mAh AAA batteries, and 4 C/D-size spacers to allow you to use AA batteries in places that take C or D-size batteries. The manual that comes with it is very brief and uninformative; you can get a better one at www [dot] lacrossetechnology [dot] com [slash] bc1000 [slash] manual [dot] pdf.
An overview of the modes:
Charge Mode: Charges 1-4 AA or AAA batteries individually at user-selectable currents: 200 mAh, 500 mAh, 700 mAh, and 1000 mAh. If you are only charging 1 or 2 batteries (for 2, they must be placed in slots 1 and 4), you can also do 1500 mAh and 1800 mAh. For some reason, it lets you charge AAA batteries at 1000, 1500, and even 1800 mAh. My advice: just don't. Let's keep it safe at 700 mAh. Display can be configured to report mAh accumulated, time spent charging, and current.
Discharge Mode: Discharges the batteries until empty, and then charges until full. During discharging phase, reports mAh discharged, time spent discharging, and discharging current. Once a battery begins charging, the display resets into charging mode. Otherwise the same as Charge Mode. Use this option if you have NiCd batteries and need to deep cycle them to remove the "memory effect," or just want to find out the current mAh capacity of a battery.
Refresh Mode: Performs multiple charge/discharge cycles. Good for old batteries that need to be reprimed. I haven't used this mode before.
Test Mode: Charges to full capacity, then discharges fully, and then recharges back to full. Reports capacity of battery based on discharged mAh at the end. I've had some troubles with this mode on new batteries. AA Eneloops, which are supposed to give 1800 mAh on their first charge out of the pack, only showed up as values ranging from 200-500 mAh when I did Test Mode. After a charge/discharge cycle, the reported capacity went up to 2050 as expected.
There are four buttons, one in front of each battery compartment, allowing you to individually configure each battery. At the bottom are the three important buttons: Current, Display, and Mode. Current cycles between 200, 500, 700, 1000, 1500, and 1800. Display cycles between (dis-)charging current (mA), time elapsed (HH:MM), and capacity (mAh). Note that capacity switches to Ah with 3 significant figures at values of 2.00 Ah and above due to lack of space for digits. Mode cycles between Charge, Discharge, Refresh, and Test. A potential con is that the bottom three buttons feel rather cheap and loose. I have a friend with a BC-9009 whose buttons have fallen off, and must be manually pressed with a pencil.
Here are my ratings:
Performance 5
Features 5
Reliability 3
Usefulness 5
Ease of use 4
Value 4
Overall 4.5
I'll round it up to a 5 for the actual Amazon star rating because I really, really like this product.
