If your battery is discharged too low to attempt this, there are battery chargers available that are designed to recover severely discharged batteries. These devices work by sending pulses to the battery terminals in order to reverse sulfation.Why do rechargeable batteries not last forever?
This is because the battery actually destroys itself over a discharge—either depleting electrodes as they discharge, or building up reaction products on the electrodes preventing the reaction from continuing. Once this happens, the battery ends up in the bin (or hopefully the recycling, but that's a whole other topic).Are Duracell or Energizer rechargeable batteries better?
