If you saw my other post in the batteries section, you might be familiar with the issues I was having with the 4sevens Single Bay Charger I got 2 weeks ago. And the fact that it was acting strange when charging 2 Soshine 18650's. (plus a couple of 16340's)
After several emails back & forth to 4sevens, they gave me an RMA... but I was doing some final tests to determine if the problem was isolated, or indeed an overal charger issue. Meanwhile, outside of those "affected" cells, the tests have been positive. To cut to the chase...I just found out today that they've already mailed me a new charger! They state that I can just refuse it, if I believe the original is working okay. Anyway, so now I'm wondering whether to keep the old, and send the new one back... or vise versa! The easy answer is to keep the new one...but then I need to package up the old and pay the postage.
What would YOU do? -- or have you "been there" before already?
