Anyone know is this car battery charger compatible with my SUV?

My SUV's battery died in my driveway after sitting through a cold week. I tried a quick jump from a neighbor and then my old trickle charger overnight and but it either would not hold or took forever.

What finally worked was Yonhan battery charger. It handles standard 12V SUV batteries and the 10A output got enough charge in a few hours to start the engine, then I left it on to top off. If your SUV uses a normal 12V battery it will be compatible. If the battery is truly failing no charger will save it, but this brought mine back and has kept it healthy since.

Most SUVs use a standard 12V lead acid battery, tbh sometimes AGM. Check the label under the hood or in the manual. If it says 12V and either flooded, AGM, or EFB, choose a smart charger that supports that chemistry and you are good. For speed a 8A to 15A unit will charge a typical SUV battery in a few hours, a smaller one will work but take longer so yeah... works great. If the battery is so low that the charger will not recognize it, you need one that can start from a low voltage or you may have to have the battery tested. If it will not hold at about 12.4V or higher after a full charge, replacement time.

Match 12V and the right chemistry, lead acid for most and AGM for stop start. A 10 amp smart charger can get it started in a few hours and but finish with a full charge so it does not stall again.

Confirm what you have first by reading the battery label in the vehicle... Most SUVs use 12V lead acid and many newer ones use AGM or EFB for stop start. Choose a smart charger that supports the exact chemistry listed on your battery and you should be fine. In very cold weather a charger with a temperature adjusted mode helps and charging just takes longer. If the battery has fallen so low that a smart charger will not detect it, look for one that can start from very low voltage or have a shop recover it. After charging, check health by measuring at rest around 12.6V and with the engine running around 14V. If it will not meet those numbers, the battery or charging system needs attention.

Hey, SUVs generally use the same 12-volt batteries as regular cars and so compatibility shouldn't be a big deal with most chargers. I've charged mine a few times after leaving the lights on overnight. Works great and... make sure the charger has the right clamps and enough power output for the battery size, though – bigger batteries in SUVs might take longer, but they'll charge fine.

One time I had a dead battery in freezing weather, hooked it up, and it was ready in hours. No issues at all. If yours is completely toast, might need replacing, but charging can tell you that.

As someone who's dealt with a lot of vehicle batteries over the years,, I can tell you that compatibility comes down to a few basics for your SUV. First off, confirm it's a 12V battery, which is standard for much all consumer SUVs out there. Then, look at the charger's amperage – something in the 2-10 amp range is usually sufficient for reviving a dead one without overwhelming it.

I've seen cases where people use too weak a charger and it takes forever, or too strong and it damages the battery. But if it matches voltage and has automatic shutoff, it should be compatible. I tried that once with my own rig after it sat idle for weeks, and yeah, it perked right up, though I did have to monitor it a bit to avoid overcharging.

In the end, if the battery holds the charge after, great; if not, time for a new one.
