    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.
