They work great for me
I bought 2 of these chargers and they have worked great on the batteries in my boat, 4-wheeler, scooter, motorcyles, garden tractors, and stored car. I haven't used it on a 6V battery yet so I don't know how the auto select feature works. I wish they included more plugs for all my vehicles.
Hook it up and forget about it.
This battery tender has worked fine for my motorcycle and auto batteries. I like that fact that it includes both a slow (1.5 amp) charge mode and a monitor mode so you can hook it up to a slightly under charged battery and forget about it. It will charge the remaining capacity and then switch to maintenance mode. Has worked fine so far.
Schumacher's SpeedChargeMaintainer maintains both 6-volt and 12-volt batteries, keeping them at full charge using float-mode monitoring. The unit will automatically switch from full-charge to float-mode monitoring when the battery is charged to prevent damage. Smart display LEDs indicate whether the unit is in charged, charging, or trouble modes. The SEM-1562A is perfect for charging small batteries, maintaining small and large batteries kept in storage, and batteries for motorcycles, classic cars, ATVs, and boats. It features a quick disconnect harness for easy removal, and reverse hookup protection in case the clamps are accidentally connected to the wrong terminals. In cold climates, this unit is indispensable for keeping batteries warm overnight and ready for starting.
