Review: So far these have been great... - ...just be sure to put it in trickle mode if you want it to maintain the battery. In charge mode it will charge the battery, then shut off. In trickle mode it will charge at a lower rate, then also shut off. However, in trickle mode, if the battery drops to 12.5v, it will turn back on and bring the charge back up. It will stay in trickle mode if the power goes out, as long as it is connected to a battery with some charge. That means that it is a reliable battery maintainer. I have ~10 of them running on tractors, mowers, and vehicles. In trickle mode they do their job unattended. I do have a couple of gripes: - The wall wart configuration is a pain. They will not fit next to one another on a power strip. I much prefer a device with an actual power cord. - I also wish that the charge mode would come back on when the battery voltage drops below 12.5. The trickle mode does this, but only charges at 1 amp max. The charge mode runs up to 1.75 amps.
Review: Great little chargers - Love these little trickle charges. Very dependable and worth having if you have multiple vehicles you don’t use as often or for winter storage. Actually showed me I had a bad 12 volt battery with 6 volts on the charger indicator. Further testing that battery with a load tester indicates it had three dead cells in that battery. Very nice to know you can just walk by and see what the charger is actually doing. Will turn off when fully charged.
