Great Automatic Charger that runs cool and is easy to operate.

Great Automatic Charger that runs cool and is easy to operate.
Purchased this charger as I have a 1982 Landcruiser 4WD with a 4.2 Litre engine which needs good cranking power to get the engine started on cold frosty Australian mornings.As the 4WD isn't a daily driver I wanted an automatic charger that could be connected for days on end, without having to worry about overcharging etc.Plugged this charger in, hooked it up to the 4WD battery (85 Ahr 720 CCA N70ZZ battery), and monitored it for the first few hours just to see what went on. The LCD displays the batteries voltage when you first connect it (with NO AC Power), then switches to it's charging cycle when AC Power is turned on.Left the battery to charge, and heard the cooling fan turn on and off a number of times during the test. Felt the charger and it was always cool to the touch, so there's no heat issues to worry about. Voltage readouts on the charger matched the multimeter throughout the test. Checked on the charger the next morning and it was on trickle charge, showing a fully charged battery on it's LCD.I now leave the charger connected on a regular basis, and the unit feels cool each time I check on it, so I can certainly give it 5 Stars. It does what they say, and seems to do it well.Also tested the charger on smaller batteries that had been sitting in the garage for a few months, and both batteries went from around 1/2 capacity to full in around 5 hours - No problems at all. One last test was on a small 7 Ahr Gel Cell Sealed battery we use for running camping lights, which was fairly flat, and the charger had no problem bringing it up to Full charge in only a few hours.Only observation I have with the charger, the AC Power Lead is quite short, so you may need an extension lead for it to reach your battery, but that's no real issue for most people. The user manual has pictures so is simple and easy to read, and the unit itself is surprisingly light. Overall I'm impressed with the charger - Works great.

I bought this for my motorbike which doesn't get alot of use. It charged the battery (21 aH) from below 75% to fully charged in about 30 minutes and then continued in float mode so worked perfectly. I tested the battery with a multimeter to ensure it was fully charged, which it was. The instructions indicate suitable for batteries up to 40 aH (although information on the rear of the device indicates suitable for batteries up to 60 aH) so as my cars have 62 aH and 80 aH batteries it would probably struggle with re-charging them but may be OK to maintain the batteries. I haven't needed to try the repair mode. The charger is very easy to operate and the on board lights give a good indication of the battery during the charging process. Overall, a great charger probably best for smaller batteries.

 I am quite impressed with this fantastic battery charger. Its very light weight and get the job done without any hassle. I used it in toyota crolla 6.8l engine car, just connected red terminal in +ve and black in -ve sign, boom, it started displaying current battery level(25% attached picture for reference). In 5 hours I got the battery fully charged. First bottom blue led lit steadily and the gradual gorwth of beattery level indication is very helpful to track how far the battery is charged. The green indicator is quite handy when it indicates fully charged state. When I disconnect it from power terminal, it displayed battery status with four blue LEDs lit. I recommend this product. It is delivered on time. It is two in one, (1)battery status/condition checker & (2) Battery charger.

This is my second GOOLOO product and I am very happy with both. I also have their jump starter and find it very helpful. This unit is well made and comes well packaged. It comes with an original AU plug and specifically made for the AU market.

This has been perfect during the lock-downs when the car is hardly used. I can keep the battery completely charged even if I do not use the car often. The manual is well written in English. It is easy to operate and it detects most of the settings automatically. For example when I connect it to a 12V battery all the 6V options are not available to select. This makes the operation of the unit really safe because you will not be able to select a wrong option.

It also has the repair option and I can use this on my child's toy car to renew the old battery.

Overall this is an excellent product for any household and easy to use by anybody.

I highly recommend this product to everyone.

I bought this one to try and maintain/extend the life of the battery in the small car we don't use that often. It's an intelligent charger, so there's little risk of leaving it connected overnight or while you're out of the house.

There's not much in the box: the charger and a manual. Plug one end into a wall socket and the other onto the battery! The unit itself also has mounting holes, so you can securely fasten it somewhere if you regularly use it in the same spot. I'd recommend keeping the manual nearby to decode the different modes it can go into and how to respond to them.

I tried it on a few older batteries that I thought were completely dead - it confirmed one was gone, but went into low voltage repair mode for the other. Left that one overnight and now it's charged!

Overall it's a great little unit, perfect for what I was after and at an affordable price.
