Should I charge new Duracell ActiveCharge NiMH cells before I use them?
It is not necessary to charge Duracell ActiveCharge NiMH cells before use because they retain up to 75% of their capacity after one year in storage. However, it is necessary to charge Duracell Base NiMH cells before their initial use as they lose 1% to 2% of their capacity per day while in storage.
