    FAQs about How to charge the backup battery power supply

    Can a battery be recharged with a DC power supply?

    You can easily recharge batteries if you have a DC power supply. All that is needed to recharge battery cells is DC current. With DC current, electrons will flow back into the battery, establishing the electric potential, or voltage, that a battery was meant to have when it's fully charged.

    Do back-ups products ship with their batteries disconnected?

    All Back-UPS products ship with their batteries disconnected to conform with the department of transportation. All current Back-UPS products will still turn on with the internal battery disconnected, however they will also give a repetitive audible alarm and flashing icon until the internal battery is connected.

    Does a battery need a DC power supply?

    All that is needed to recharge battery cells is DC current. With DC current, electrons will flow back into the battery, establishing the electric potential, or voltage, that a battery was meant to have when it's fully charged. A DC Power Supply is needed that allows for adjustable voltage and current.

    How much current do you need to recharge a battery?

    And the answer is, the battery you are recharging should come with a specification of the amount of current needed to recharge the battery. For example, a Duracell Rechargeable 'AA' Battery 2650mAh battery specifies the standard charge of 270mA for 16h. This means to recharge, you must supply it with 270mA.

    Can a battery be charged manually?

    Batteries can be charged manually with a power supply featuring user-adjustable voltage and current limiting. I stress manual because charging needs the know-how and can never be left unattended; charge termination is not automated.

    What should I do if my battery is not charging?

    Disconnect the charge. Also disconnect the charge after 16–24 hours if the current has bottomed out and cannot go lower; high self-discharge (soft electrical short) can prevent the battery from reaching the low saturation level. If you need float charge for operational readiness, lower the charge voltage to about 2.25V/cell.
