Review of Charger Heseny HXY-18650-2A (4.35 volt)
Heseny HXY-18650-2A (4.35 volt)
This is a 4.35 volt charger, i.e. it cannot be used for the normal LiIon batteries, but only 4.35 volt cells like LG 18650 D1 3000mAh (Pink) and Sanyo UR18650ZTA 3000mAh (Magenta). I bought it from Fasttech and it was shipped in the usual envelope. Only contents of the box was the charger, nothing else. Specifications on the back says universal voltage and 1A charge current. At the + end is a + mark and the connections will work with flat top batteries. I am missing some big letters saying 4.35 volt. The - end has the usual springs and red/green leds. The charger can handle 70 mm long batteries. The bottom of the slots is marked with battery size and orientation, but again without any warning about 4.35 volt. Measurements
The rated 1A charge current is difficult to see in the chart, because the charge current drops with voltage and with empty batteries it is dropped to about 700mA. The led switches to green after about 6 to 7 hours, this is before the batteries are charged, wait about 3 more hours and the batteries are up to 4.35 volt. The charger does never turn the charge current off. As usual the yellow line shows where the charger says the battery is charged, i.e. led changes from red to green. The second channel is slight faster. Running both channels at the same time, does not change the charge speed. Testing with 2500 volt and 5000 volt between mains and low volt side, did not show any safety problems. Conclusion The charger will fill 4.35 volt batteries and as long as the batteries are removed when they are full, the charger is useable. But without any termination, misleading ready led and slow charging I would look for another charger. I am missing a 4.35 volt marking on the top of the charger. Notes The tests were done at 110VAC mains power. Here is an explanation on how I did the above charge curves: How do I test a charger
