UPDATE: (02-21-2011) It has been more than 2 1/2 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 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 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. La Crosse Technology BC-700 Alpha Power Battery Charger
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.
[update on June 13, 2008]
Recently the price of BC700 has settled to a level much lower than that of BC900 (partially because the price of BC900 has gone up), so it is now an excellent buy - especially if you intend to buy some low-self-discharge NiMH cells separately. In light of this, the criticism in my original review now seems unnecessarily harsh. Too bad I'm not allowed to change the star-rating for this product.
[Update on April 7, 2010]
I hope my overly critical review above did not discourage anyone from buying the BC-700. As of this moment, it is the best value if you are looking for an advanced battery charger/analyzer. This is because:
- The BC-9009 has been recalled recently due to excessive overheating/meltdown incidents.
- The Powerex WizardOne Battery Charger-Analyzer is more powerful, but costs twice as much as the BC-700.
- The newest La Crosse BC500 has severely limited functions compared to the BC-700 (see my review for details), yet it costs more.
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.
I am a medium to heavy user of AA & AAA rechargeable cells and also an early adopter - started with 300mah Panny NiCds many years ago - I remember the excitement when 450mah versions were released! :-) Over the years I graduated through the technologies and was using Sanyo NiMH 2500mah cells till I recently discovered Eneloops - they are simply amazing! Now back to the charger review - I have always been an advocate of chargers that have individual charging channels / circuits and can charge 1,2,3 or 4 cells individually. My earlier charger was a Panasonic BQ390-A that still works very well and is very portable. However, faster & adjustable rate charging currents, battery reconditioning, testing etc. drew me to the BC700.
I did not consider the BC900 as the 8 cells bundled with the package were of no use to me (I have enough to last many years) and the 1.8A charging current capability on the BC 900 is something that I would never use.
Amazon was great in it's order processing - as always. I received the charger on schedule. The quick user guide printed on the back of the charger package is a really nice touch. I was eager to test the unit and unpacked and set it up. And that is when I noticed that -ve tab for the AA cell in the 3rd channel was too far behind to connect with the cell. After looking at it closely, I figured that the tab was bent backwards - at least that is what it looked like - very dissapointing for a brand new unit that was packed so well! This is the only reason that I cannot give this Charger a better rating - poor manufacturing processes and very poor quality control!
Having never seen the innards of an intelligent charger, curiosity got the better of me and I decided to try and fix it myself. On dismantling the unit completely and removing the PCB - I discovered that the tab was indeed bent back and had not engaged with the plastic channels on the top of the case that hold these tabs in place when the PCB is inserted. After some delicate work with a needle nose pliers the tab was straight once again and it engaged with the channel.
I must warn others toying with the idea of opening their units - DO NOT TRY IT unless your unit is out of warranty AND you really have a need to AND you are a very capable and advanced electronics hobbyist - putting the BC700 back together is a very complex task - especially aligning the LCD panel contacts with the contacts on the main PCB - if that gets spoilt, the LCD display will be dead and so will the charger!
In my case I managed to put it all back together again and the charger works perfectly now. It is very easy and intuitive to use and does everything that it is supposed to. I prefer the 500mah charge rate and it charges 4 AA Eneloops in a little over 4 hrs.
So this is a happy ending to the story/review. As mentioned earlier, my only concern is with the Manufacturing and QC processes followed by La Crosse - it was indeed very disappointing to see such a basic (and visible) flaw in a brand new unit! It makes one wonder whether there are any other flaws that have not been noticed till now ... I guess time will tell ... - Rechargeable Batteries - Battery Charger Aa Or Aaa - Nimh - La Crosse'
