An intelligent 4-stage maintenance charger for 6 or 12 volt lead-acid batteries. Maintains and extends battery life by constantly monitoring and correctly charging the battery indefinitely across four stages: pre-charge, constant current, constant voltage and float charge. Select from four charging modes, including: 6V/1A (slow), 12V/1A (slow), 12V/4A (fast), and 12V/4A (low temperature). The LCD interface clearly displays modes and measurement detections to ensure ease of operation. Safety features include short circuit and reverse polarity protection, wrong battery prompt, over temperature protection and power down memory. Numerous charging options make this a great choice for many vehicle, home and industrial battery charging requirements. The handy retractable hook means you can hang it where you need it.

NOTE: These chargers are not recommended for long-term "maintenance" charging of unsealed lead-acid batteries, the types with removable filler caps and liquid elctrolyte. Long-term continuous float charging of this type of battery may cause loss of water from the electrolyte, ruining the battery. If you are intending to use this charger on these batteries please use an appliance timer such as MS6113 to automatically limit the charging to 30 minutes or so per day.
