La Crosse Technology BC-9009 AlphaPower Battery Charger Reviews
I must say that I thought all chargers were more or less the same. After purchasing a myriad of chargers and batteries I now realize that the various batteries and chargers make all kinds of silly claims that rarely meet expectations. I use AA NiMH batteries for some electronic devices (mice, radios, etc.) and my two Canon cameras. Since my S2 and S3 cameras have a healthy appetite for batteries I decided to check out some reviews and buy from Thomas-Distributing. They are an excellent, if pricey, source for rechargable batteries and chargers. The array of choices is dizzying. I now own two LaCrosse BC-900s that I purchase from Amazon at a much better price. Thomas-Distributing also sells the full line of Maha chargers that seem to garner top ratings but I think the Maha model that is similar to the LaCrosse, costs more and offers fewer features. I own two lower-end Maha chargers and I think they are great. But, the flexibility and information offered by LaCrosse makes this model the best and quite possibly the only charger for AA/AAA batteries that you will ever need. The AC adapter is external and adds bulk so this charger is perhaps less compact than those all-in-one plug in the wall types. But the features built into this model make this my absolute favorite. Other chargers require that you charge two batteries together and the LaCrosse allows you to charge up to four batteries independently at separate rates using separate functions. This is important if you have different batteries with different capacities. The display allows you to monitor each battery for current/time/voltage/capacity side by side. This way you can refresh one battery while discharging one battery while charging one battery… you get the idea. Unlike the Maha model, the display shows all four battery status levels side by side. No scrolling through menus for each battery one by one. At a glance you can check each battery and compare it to the next battery. Most chargers from department stores or camera shops are designed to rapidly charge the battery within a few hours. The high current does charge more quickly but generates heat and reduces the effective life of the battery. Furthermore, those blinking lights don’t have accurate meters so you have no information about the true capacity and no idea about the condition of your batteries. Some chargers have a conditioning button which discharges and recharges but still does not give any accurate information. The LaCrosse lets you charge, discharge, measure, recondition and effectively revive batteries. I usually use the lowest default current and refresh my batteries over one week. This takes time but brings my batteries to full capacity. The maH capacity of the battery printed on the battery is often overstated so here is your chance to compare the brands of batteries. (I think the Powerex and Sanyo batteries from Thomas-Distributing are the best.) If you are in a big hurry simply choose a higher current and rapidly charge your batteries. Did you know that any device using multiple batteries will have a battery life limited by the battery with the lowest capacity? Let me explain, If you have four AA batteries that state 2400 maH capacity each, if one battery is weaker than the true 2400 mah (lets just say 1800 maH) then the combination of all four batteries in your device will function to a capacity of only 1800 maH. I’ll illustrate… bought four expensive 2400 maH batteries and found that they would run out faster than my old 1800 maH batteries! Using the LaCrosse I discovered that one battery had a capacity of only 1500 maH and the other three were about 2200 maH. I refreshed all four and they all exceed 2500 maH now! Now I take several hundred photos on a single set of batteries. After purchasing eight chargers and throwing away most of them, it’s clear that this is the one charger that really shines. It will save you money by reviving old batteries. The price is great and the charger comes with a set of AA and AAA batteries. The included battery adapters may come in handy in an emergency if you need C batteries for a flashlight or toy. My only complaint is the external AC adapter which makes it less portable; I think this is really a minor quibble. If you prefer a rapid charger without all these features check out Maha. Hope this helps.
