An intelligent 3-stage maintenance charger for 6 or 12 volt sealed lead-acid batteries. Automatically diagnoses, recovers and recharges with up to 1.5A output current. Charge modes include constant current, constant voltage and floating charge with the unit conveniently adjusting charge settings to suit various sized batteries and charging requirements. Easy to use with power and charging light indicators, this unit also includes short circuit and reverse polarity protection.

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 to automatically limit the charging to 30 minutes or so per day.
