AA battery charger info
If you own a digital camera or remote control, or any electronic device that comes with AA batteries, chances are that you also have AA battery charger. A battery charger is a device used for storing energy in a secondary device or cell which can be also called battery. When we plug in a charger electric current runs through it to the batteries and recharges them. I bought my camera long time ago and used many alcaline batteries. I used them and tossed them in the trash can. After using disposable batteries (they were cheaper than rechargeable) for quite some time I gave a thought over buying rechargeable batteries. I often use my camera, therefore I need AA battery charger. I calculated how much money I wasted on disposable alkaline or energizer and decided to give a shot on AA battery charger. Well, I spend almost 50 dollars on Albinar recharger and 4 AA Albinar batteries, but it was worth it. Almost 4 years have passed and I'm still using them. Of course, the working time is not as long as it was in the beginning, but 4 years is quite a long time. Albinar charger get my batteries up to full charge in 4-6 hours working under quick 550 mA charge mode. There is another standard charge mode of 230 mA whicg would get your batteries up in 14-16 hours. Now, that's a really slow charger.
NiMH AA battery chargers
Let's talk about quicker and more efficient NiMH AA battery chargers. Most battery chargers are made for both AA and AAA batteries since these batteries are the most common types. These battery charges usually have 4 or 6, some even 8 slots for batteries. Battery chargers that are sold in USA usually differs from those sold in Europe. If you're a european, make sure you have an adapter and your battery charger can work both with 100 and 220 volt outlets.
A normal and efficient AA battery charger should have a charge and discharge mode. Some vendors suggest that if you want your new batteries working longer, you should charge and discharge newly bought batteries for 3 times without using them.
The best AA and AAA battery chargers have built-in protection for preventing overcharging. One of the best chargers in the market is LaCrosse BC-900 battery charger. The price in Amazon varies from 35 $ to 40 $. It has such features as charging and discharging current, accumulated capacity and terminal voltage. There is a small LCD display that helps you monitor charging process and one more thing - you can charge both AA and AAA batteries at the same time. This kind of charger is called "smart" charger. It has 4 separate charge channels, therefore you can charge one or two, or four batteries at the same time. Besides this charger comes with four AA and four AAA batteries (altogether 8 batteries).
Maha Powerex MH-C9000 WizardOne
Another super cool device is Maha Powerex MH-C9000 WizardOne Charger. It is the most advanced MAHA product development so far and the most significant product released in 5 years. It can charge, condition and analyze from one to four AA and AAA batteries. It presents individual and independent operation of each slot. It has a large LCD monitoring screen and digitally displays capacity, voltage and time elapsed. Besides, it has adjustible charging rate from 0.2 to 2.0 A. A user can even program the number of cycles to charge or discharge in the cycle mode. The costs of this charger varies from 48 $ to 60 $ on various websites. You can buy it on Amazon for 55,5 $.
Generally speaking the fastest battery chargers will cost you from 48 dollars. The chargers that charge batteries in 6,7,8 hours are considerably cheaper. You should know that even fastest chargers can recharge batteries only in 1 hours, no less. If you don't want to spend on fast battery chargers 10 or 15 extra dollars, I think you can buy standard chargers just fine. So called fast chargers (15 minutes chargers) aren't always the best. They do not always charge in full, the charged batteries get burned out or get little life even after a full charge. If you want a complete and full recharge my suggestion is - stick with chargers that charge for at least 1 hour.
