Review on 🔋 YONHAN 5 Amp 6V/12V Car Battery Charger Maintainer - Trickle Charger for Car, Boat, Motorcycle, Lawn Mower, Marine Sealed Lead Acid Battery and More by Chuck Derrick

Pulse charge has been running for 7 hours but there is no capacity or charging results. Can't comment on how well this works yet, but I'm using an extension cord with a truck battery. The photos show the charger connected in this way, but the booklet that came with it tells you very little. After another 9 hours I will check again and switch to pulse charge mode if it doesn't switch itself. I also noticed that there is no labeling on my device and there is a Russian font in the instructions. I like the size and hope it works.
