Review on ⚡️ TECMATE OptiMATE 6 Ampmatic: 12V 5A Charger & Maintainer for Sealed Batteries by William Sanchez

Thing is amazing, I installed a new AGM battery on a sailboat that was refurbished a year ago, the only thing that came with it was an interior light with an LED Lamp, battery held its voltage all the time and then I installed the audio system, marine radio and fish finder/fish finder. For several days I listened to FM radio for a total of about 1 hour which drained the battery to 7V, the radio would not turn on and even the interior light looked like a candle. I plugged in a Sears charger which claims to fit all battery types, 48 hours later the voltage hadn't changed at all, dead I thought my battery was dead before I could even use it. OK, now the Sears charger claims to fit all types of batteries, probably it's referring to batteries made in Mexico, Brazil, China, etc. Boat on the box. .This charger was plugged in for 72 hours, in a few hours I recharged the battery to 12.5v, then ran some tests and everything completed as per the manual, including sporadic charging when I listened to the radio for a while two Cases. I don't want it to be plugged in all the time, but knowing that it can charge the battery in a few hours is great. I have a solar panel that keeps the power going when the boat comes out of the garage and is ready to sail. for the worldwide electrical systems - another plus point, I am very satisfied with the product.
