I have a charger for 9 years. It is a top charger and would buy it again calmly. I highly recommend it to all. This is one of the best on the market and also in the price / performance ratio. After years of moderate intensity use (both at home and on the road, and holidays, etc.). I easily vykloktal power connector, so charging from time to time been reset. I resolved that I removed the connector and the cable přiletoval fixed. It tramples on. Otherwise no problem and maximum satisfaction. Charger monitors as cell temperature, and Delta moment, so it's smart charging without overcharging articles. Perfect function is also reviving old articles or tes cell capacity. Using other functions, you can leave the battery before recharging completely, giving it formatted and better battery recharges Charger handles both micro and tužkovky. It operates with a capacity of 3000 mAh / article, but if I know, so far no such capacity battery manufacturers failed to overcome. In conclusion, one trick: if you load a completely totally discharged cell (and does not have to be a dead piece) that has no voltage, charger and insert it does not detect! It happened to me a few times. I solved it so much that I took a 4.5 V battery and attach it to the dead to the article about a minute (plus + and minus -). Article will exhibit measurable voltage charger and then recognizes him. Then you can do anything with Article (revive, test, charge, discharge, etc ..)
4 shafts - each can at one moment to perform a different function for each manhole can also at the same time watch another value (cell voltage, charge current, time, size of the current to charge the battery) charging current selection option discharge currents
Perhaps there could be a backlight .. but that you invent. Someone had mentioned a cheap buttons, come to be just fine to me, are plastic function well, it seems to me better than rubber buttons that time dealings and then mostly angry. If I were a designer, I do not know how I would solve those buttons better.
