🔌 Efficient 12V SLA Battery Charger: 1300mA with Short Circuit Protection Review

As always, first connect the positive cable to the battery and then disconnect it in the opposite direction. I checked before and after connecting with a digital voltmeter that it works correctly - as it is. It has been used several times with no problems on a couple of small batteries. In my opinion it is good value for money and I would recommend it to a friend.

Seems to do a great job of charging my kids 12v batteries. The charger has an orange-red indicator while charging, which turns green when the battery is fully charged. I keep an eye on it throughout the day while charging, so I'll be sure to remove the charger as soon as the light turns green. I was told that it has no shut off or safety feature to stop charging and therefore could damage the battery if not turned off after charging is complete. I wouldn't leave any of them overnight just in…

I think it works but I don't know because; My problem is that there is no guide or guide to know when your battery is fully charged. Another problem is that not everyone knows that the minus must be connected LAST, otherwise it may suffer. There should have been a warning about a product like this that deals with potentially dangerous products. Luckily I knew, but what if someone didn't? Also, the covers on the negative and positive sides are slippery, which can lead to touching wires, which…

I bought this charger to get colloidal silver and colloidal copper. I have already made two batches of colloidal silver and am now starting a batch of colloidal copper. So far this has worked great. 👍Note: If you're using this to make some sort of colloid, make sure what you're doing doesn't build up too much debris. In this case, the charger lights up red instead of green. It should have a green light when you prepare your colloid. I figured it wouldn't work anymore and I'd have to buy a new…

Either the device I received is defective, or this product is not a three-stage charger (see Wikipedia and other sources for a description of the three-stage (smart) charger. The three-stage charger changes the output voltage and therefore the current when the battery goes from discharged to fully charged in three stages.After the battery is fully charged, the charger should go to the final phase, which is the charging (charging) phase, where the voltage is about 13.5 V. This charger has its…

I don't usually give rave reviews but this little charger works great. I have several famous chargers that I use. However, there are times when they simply refuse to charge batteries whose voltage has dropped below a certain level. Sometimes such caution is warranted, but not always. In my case, I just replaced the batteries in the backup power supply for someone. After a few weeks, they noticed that the backup power supply was disconnected and would not turn on. It turned out that the…
