Seems to work, but erratically
I was pleased to see this device, as it really annoys me having to throw out alkaline batteries. Here is an opportunity to get some more life out of them so I don't feel quite so bad when they finally make it to the landfill.<br /><br />I tried this on duracell and energizer alkaline AAs and it seems to have re-energized them, although it does seem a little inconsistent.<br />One thing to note is that the LCD display is not reliable. I have 4 AA batteries in the device overnight and they were marked as charged in the morning. I pulled back the spring loaded connectors in the unit and reconnected to the batteries and then all 4 were no longer marked as charged and kept charging again for another few hours. I did a quick check of all the batteries as they came out to see if they would operate a small 2 x AA flashlight. Some worked fine, others hardly at all. If I find my voltmeter I may make this a little more scientific.<br /><br />So, overall I give it 3 stars at present as it seems to work in part. I won't (and didn't) expect miracles for the price.
