Review on 🚗 RD510 3-in-1 Car Battery Tester, Desulfator & Regenerator | 12V 4Ah-100Ah Smart Automotive Charger with Pulse Repair & Trickle Charging Capabilities by Troy Hamilton

I used to have a separate charger and tester, so I had to take both with me if I had to. The charger is limited to 5A, but that's all you need before you start removing the covers and venting the cells anyway. This device really is better than most others on the market. Here's why I really like it: - Finally a charger that shows the actual charging current. Most devices simply show the setting you have set (even if they have a display) - Multifunctional display, bright and easy to read - Can test, repair and charge batteries. I tested it on regular filler and AGM and it worked great! - The tester is fairly accurate (within 10-15 CAA) of the professional tester I compared it to. You must ensure the battery posts are very clean before attaching the clamps for accurate readings. This type of tester tests the battery's internal resistance, so a poor connection between the terminals and clamps will result in inaccurate readings. It has a very functional menu that allows you to turn the sound signal on and off. It's amazing how many of these devices have annoyingly loud beeps that you can't even turn off. - You can set the charging time manually if you don't want to rely on automatic mode. - He has a fan! Many blocks are sealed so they will eventually overheat and fail. Unfortunately, it's not waterproof, but I would have preferred good cooling to resistance. I kept them in a dry place during use anyway. The only thing that could be improved is the cables. Cables with alligator clips and the power cord feel fragile and are easily damaged. The clips themselves are good and strong. It also doesn't have a supply mode, but it's still rare to find. I can't say anything about the repair function. This varies greatly depending on the condition of the battery, so if your battery has already served its purpose, repairing it will not do much.
