Not for Older Cars
In 2011 I purchased an inexpensive trickle charger from a local retailer to keep the battery in my 2003 Hyundai Tiburon charged. It worked until it died in November 2022. I read the positive comments on the GooLoo Smart Battery and decided to purchase it. As much as I tried it would not keep the battery charged on this vehicle. However the GooLoo worked great for our newer Hyundai's, but the not the 2003. For this reason I didn't return and kept for the other cars.I brought another inexpensive trickle charger on Amazon and it worked perfectly! At a recent car show I was talking to another car enthusiast who mentioned they experienced the same problem with similar smart chargers when storing their classic cars. Words of the wise.

Bought 2
Working great. I use one on my Indian and another on my C8. I did have to shave down the plug (just a tiny bit) with a razor blade to get it to fit into the Indian (blame that on Indian, idk). I bought another brand before this one and it broke after using it the first time.

Does what it's supposed to
I was going to reorder the brand I have three of since I know what the silly pictures mean. The display on this one is a little more intuitive but I wouldn't have guessed 12M was for maintenance since I assume/hope that if it's in charge mode it would switch to maintenance when fully charged? It would be nice if it displayed the charge voltage rather than just FULL when in Maintenance mode. Checking with my OTC brand VOM I saw 13.8V when the charger displayed FUL. Disconnecting it the battery was indeed at 13.8 and dropped rapidly (13.6V in about 30 sec). I think nominally the battery can hold ~13.2V when not connected to a load. Reconnecting the display showed 13.6 and rapidly climbed up to and help 14.4. IIRC that's about the voltage the alternator supplies. It's a bonus that this charger can be used as a 12V supply. Not sure when that might be useful but if you have something that is powered from the "cigarette lighter" I guess you could use this outside of a vehicle. I think maybe it's to replace a battery of a car that's in storage but you want to keep the memory and maybe have the dome light work.The backlight on the display is a nice feature.

A Bit too short.
Seems to work good. Cables and / or power plug cord is too short. Does not reach battery like all the previous chargers. May work fine for most.
