Generally, when a non-rechargeable battery runs out of power, it retains about 20% of energy. When you connect it to an alkaline battery charger, this energy is reactivated and will last longer.

After this, the battery will have been completely worn out and needs a replacement. If you can, check for signs of leaks after charging it for the third time.
