🔋 BMK Smart Battery Charger: Portable 12V 5A Maintainer for Car, Boat, Mower, Marine Battery – Fast Charging Trickle Charger with Detachable Alligator Clips & Rings Review

My car battery in the car I only drive about 2000 miles a year, weekends and sunny days, barley to run. Received the BMK charger quickly and the connection instructions with pictures were easy to follow. and explained the loading steps. My battery was charged to 100% in 48 hours and a trickle charge is currently being applied.

This is a great charger for keeping my RV batteries in tip-top shape over the winter. I just wish there were more ads for this type of device such as B. the actual battery status and the phase that the charger is in. But the lack of information is common in such devices, so it doesn't matter. I hope it lasts longer than what I previously bought.

Inexpensive, easy to use protective covers to keep the ends of the connectors from touching, simple and effective. I've been using a Minnkota charger for both of my marine batteries and everything has been fine, but lately it's been overheating and eventually died. I researched this and am pleasantly surprised. Affordable and three times more effective than others. It charges my batteries faster and fuller, I will definitely buy again. Excellent purchase.

I use these to keep our farming equipment's batteries charged as some parts can take days (or longer) between uses. A tractor has several on-board computer modules that constantly consume a small amount of energy. This charger has worked very well for all of them. The only problem was that I forgot to take it off and drove into a frozen field - it fell and I drove over it. Not the charger's fault, just a dumb case! I've ordered two more!

This is a simple battery charger: small, easy to use, easy to store and does the job well. Love the fact that it has a sealed case to protect the electronics and make it splash proof. My only gripe, and it's a small one, the documentation doesn't make clear the difference in what the FLASHING and STEADY LEDs mean, although it becomes crystal clear after a few minutes of use. Basically thumbs up. I would buy it again with great pleasure. This review comes after just a few days of using Group 31…

Digital meter confirms charging 4.99A from a fully discharged 18Ah battery, which is not coincidental, and a charging current of 5A indicates! The charger delivered a constant current of 5A (voltage changes as needed) from empty (battery at 10V) to over 75% charged. Then the current decreased and dropped to zero as the open circuit voltage approached 13V. And stayed on zero as it should be! (Make sure the charger and charge are unplugged, then let the battery sit for a few minutes before…

EDIT: As I keep testing/using this thing I realize as some other reviewers have written that it just DON'T PAY. Measure battery voltage, charge overnight, after 12 hours the battery voltage is LESS than when you started. My car's parasitic current draw (around 50mA) will drain the battery (as expected) but the charger will NOT charge it. I need to leave it running (charging the generator) or hook it up to another offline charger to see the battery charge. ORIGINAL REVIEW: I wasn't expecting…

I bought this charger thinking I could use it to charge my car battery. nope It's a 'smart' charger that seems smart enough to determine if I'm worthy of a charge. I can't. When the car battery I bought last November was too weak to start my car, this 'smart' charger decided the battery was also too weak to charge, so it politely declined. I had a dead battery and a charger that refused to charge it. Correct me if I'm wrong, but isn't that the only reason to buy a charger: to charge the…
