  • I have purchased one of your batteries. Where can I purchase a suitable charger?

    Power-Sonic offers a wide range of chargers suitable for batteries up to 100AH. These chargers can most likely be purchased from the same source that sold you the battery. Both our charger specification sheets and our battery specification sheets, as featured on our website, specify the correct charger required for the Power-Sonic battery. If your battery source does not offer chargers, our customer service department will be able to direct you to a suitable distributor.

    Contact details for customer service are as follows:

    Tel: 619-661-2030
    Fax: 619-661-3648

  • How can I determine how many hours will it take me to fully charge one of your batteries?
    Charging times can vary substantially depending upon so many variable factors including:
    • Depth of discharge
    • Charging temperature
    • Size and efficiency of the charging equipment
    • Age and condition of the battery For further information about charging please see pages 12-19 of our Technical Manual.

    To access our Technical Manual please go to the Literature - SLA Batteries section of our website
  • Where can I find the user manual on instructions for operating your charger?
    These are available for download in PDF form from this website. Please go to Literature and scroll down to SLA Battery Charger Operating Instructions.
  • Does overcharging damage batteries?
    As a result of too high a charge voltage excessive current will flow into the battery, after the battery has reached full charge. This will cause decomposition of the water in the electrolyte and premature aging. At high rates of overcharge a battery will progressively heat up. As it gets hotter it will accept more current, heating up even further. This is called thermal runaway and it can destroy a battery in as little as a few hours. For further information about charging please refer to our Technical Manual pages 12-19. To access our Technical Manual please go to the Literature - SLA Batteries section of our website
  • Can I charge Power-Sonic sealed lead acid batteries with an auto charger?
    The electrolytes in an auto battery and a sealed lead acid battery have different specific gravities. Different chargers are required for each type. Using an auto charger could result in heat being generated inside a Power-Sonic battery; this in turn would shorten the battery life. Please contact our technical department if you need help in determining a suitable charger.
  • What is thermal runaway?
    As a result of too high a charge voltage excessive current will flow into the battery, after reaching full charge, causing decomposition of water in the electrolyte and premature aging. At high rates of overcharge a battery will progressively heat up. As the battery gets hotter it will accept more current heating up even further. This is called thermal runaway and it can destroy a battery in as little as a few hours.
  • I have purchased a 4 volt battery from you, how can I charge it?

    Power-Sonic only offers 6 and 12 volt chargers and as such we do not have a suitable charger available for charging a single battery.

    For assistance in locating a suitable charger please contact our Technical Department.

  • Can I open the charger case to make modifications?
    Chargers do not contain any customer serviceable components and should not be opened under any circumstances. Doing so would void the warranty and could lead to damage to property and/or result in personal injury.
