About HULKMAN Sigma 1 Amp Automatic Car Battery Charger and Maintaine
Overall Feedback:
77% positive
92% were impressed with the fast charging speed
After charging the battery for a day and a half, I measured the voltage of the battery to be 12.1v.
90% found it compatible with various devices, but 10% didn't
I can charge just about any 12v battery with the battery charger.
The product claims to be AI driven, but manual selection of battery type is required.
94% found it easy to use, but 6% found it difficult
The display is bright, easy to read, and beautiful.
The charger is easy to use and read, except for the issue with the terminal clamps.
89% praised the built-in safety features, but 11% experienced issues
I am concerned about the effectiveness of the battery repair mode. It only displays the repair function and shows the battery as full, without indicating whether the repair function is actually working.
