A mains powered Lead Acid battery charger designed for 12V batteries. Features intelligent automatic charge controller to stop charging when the battery is full and maintain the battery with a 'floating' charge mode. This feature allows you to leave the charger connected to the battery without risk of overcharging and know your battery is always ready to go. Includes a 2m long cable with interchangeable DC plug and Alligator clips. 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.
