Customer Review: Uneven charging!
Summary: 3 Stars
I bought a package of the following,
T-1199B Universal Battery Charger With Timer Control + 8 Tenergy D 10000 mAh High Capacity Batteries.
I also bought a package that had just one more 4-cell charger. That way, I could put all eight D-cells on charge simultaneously.
Charging those batteries with the bundled chargers, I became concerned that the batteries are being charged unevenly. I noticed that the batteries felt to have different temperatures, so I measured them all with my (kitchen) infrared non-contact thermometer. Right now, the four D cells in one of the chargers showed these temperatures, Fahrenheit: 110 F, 97 F, 92 F, 88 F. The other charger has four more D cells, which show temperatures in a similar progression. Both chargers have made the room smell of hot electronic components - many of you know what I mean.
The power supply end of the two chargers indicated 118 F and 120 F, respectively, just now. I checked the end with a slots in the case for air to circulate, and the temperatures I reported are the highest indications that my thermometer showed as I scanned over the case.
I suppose that I am getting my money's worth, because these chargers were cheap (particularly when bundled with the D cells). And, the batteries must be charging, since they are warm. (The room is only about 77 F.)
Note that, as other reviewers already said, this charger does not monitor the batteries and charge them until they are full. This charger only charges its batteries for a fixed time period, with no regard to what the batteries need. That does, indeed, protect the batteries from cooking indefinitely on the charging current. However, that behavior is dumb (ignores the condition of the batteries) and can subject batteries to harmful continued charging when they are full.
I'm not happy, and I have now ordered a better charger! (Amazon didn't offer one, that I could see.)
