Not good
from Gerald Nicholson on 2/25/2020
Used it on their Li-ion battery 7.2v 7000maH used for a Metz 60 CT-1.Aafter about 10 - 12 charges suffered a catastrophic failure due to internal fault. Using a 1amp multi-volt (3 - 12v) power supply ever since. Battery still seams OK but not its best after several years
