12V/6Amp Car Battery Charger, Smart Fully Automatic Battery Charger with Temperature Compensation for Most Types of Lead Acid Batteries, Red, AC Connection Required

I’ve literally used this charger a million times for my car batteries — it’s that reliable. Fully automatic, smart charging, and it handles temperature changes well, so I never worry about overcharging. It’s easy to connect, and it works with 12V batteries perfectly. Definitely a go-to for keeping batteries topped up, especially during winter or if a vehicle sits unused for a while. Pros: Fully automatic and smart Handles temperature variations Easy and safe to use Makes a nice fan noise which I find relaxing hahah Cons: cable too short Overall, a must-have for anyone who wants a hassle-free car battery charger.

Good product saved the car battery

Purchased to use on my 2011 VW Golf MK6 as it was failing to start, didn't have my hopes set too high but figured it was worth a shot. Hooked it up to my car battery and it was detecting and displaying correctly on screen, and after plugging into the mains the battery began charging from the 20-40% region. I checked hourly, and after around 4 hours it hit the 80-100% region. I gave it another 3 hours and it was still in that same charge region (I figured post-80% it begins trickle charging as to not damage the battery?) so I stopped there, ~7 hours total. Most importantly, after disconnecting and going to start my car it did so perfectly, smoother than it ever has since I first bought it last year. Value for for money is great, about 1/3 the cost of a new battery so I'm impressed. Reason for the 4 stars is the cables (both the positive and negative cables, and the cable for the 3-pin plug) could be a little longer, as mentioned by many others but it's not a dealbreaker.

It works well, does what it says on the tin , at least the once I have used it. Simple to use,

Fantastic buy

Great Price

I brought this because my car battery kept dying - it is quick and easy to set up, it seemed to charge my car battery to a point where it was workable in just a few hours. It’s a small, light, sleek and nifty gadget that has saved me a lot of money!! Great quality product.

Very good unit. Works fine for a Classic Ford lead acid battery
