My landlord has his car here for storage but needs it every now and then. I was about to take it out to keep the fluids going and found out the cars dead. Tried a different but popular brand battery charger maintainer and after a jump start. Let it charge overnight. Woke up to try it again and found out it was dead still.
Got this shipped same day and immediately it started charging the battery without needing the force charge. Let it sit overnight and surprised the performance was much better. Yes it's slowly charging (box says 30 hours or more) but the connectivity is reliable and strong. Temperature I noticed was warm but not hot. And checked on it again and saw the indicator went to above a quarter charged which is already much better.
Small and powerful, it will charge batteries from dead but it is a slow charge. Very much value for money when it is on sale but it works so well I'm going to use it on my weekend car that sits in the garage or maybe buy a second one because it works so well and has options for other kinds of batteries!
