Good charger for its price. In heavy use, it lasted about 4 years. Permanently connected to a large 12-volt 140 Ah battery that I use as a backup in case of power outage. It always kept the battery charged without overcharging it. When it reached 100%, it entered a maintenance process.
Unfortunately, all good things don't last forever and our charger gave up on us. In the photos, it can be seen that some components couldn't handle the heavy workload and "burned out". Luckily, they didn't catch fire, they just smelled burnt and the charger died.
I had other chargers of this category, but this was the only one that reached the true 10 Amps in the charging process and, when reaching full charge, it lowered the Amps so as not to strain the battery. It also immediately restarted and continued charging after a power outage.
Even though it burned out after 4 years of continuous operation, I ordered it again because it served me perfectly all this time. If the new one lasts another 4 years, I will be equally happy.
For someone who needs it to occasionally charge batteries, it is the best.
