I love these batteries! Since they are 2000 mAh (mind where 2100 mAh, don't know why) these batteries last a long time. They last even longer than my one time use alkaline batteries per charge. That's right per charge. I'm not talking about lasting longer in the life time of the batteries because that's obvious since they are rechargable. I'm talking about fully charging these batteries only one time and they still out last Durecell one time use alkaline batteries. Finally rechargable batteries that perform better then one time use batteries.Alkaline batteries are yesterday's technology meaning they are not good enough for today's high powered electronics. Either buy one time use Lithium batteries or get these. These batteries are more cost effective since they are rechargable. My digital camera used to eat through alkaline batteries within a few hours but with these batteries I can last days on only one charge. Now that's a huge increase.
This advice is very important...to get the best performance out of these batteries and any rechargable batteries you have to fully charge and discharge the batteries at least 3 times. If not then you might get poor performance. This is just a good rule to remember because it's true for all rechargable batteries no matter what kind they are.
The recharger itself isn't that bad. I only roughly timed it but it takes about 3 hours to fully charge. It's well worth the wait for the stamina it gives you in battery life. One minor problem I did notice is that the top two connectors charge faster than the bottom two. Not a problem if you are only charging 2 batteries at a time. When you are charging 4 batteries just move the bottom 2 batteries to the top when the top 2 are done. Other than that it's a great charger.
