Q: Can i use it to charge 12v SLA battery? Questioned by bobseee, 11-May-2016

Dear customer, the full charged voltage of a “12V Sealed Lead Acid Battery” is often about 14V. So if you use this charger, your battery will not be fully charged. Please follow the full charged voltage of your battery. If the full charged voltage is greater than or equal to the charger output voltage, then obviously you can use this charger.
