Fo how many hours should the AAA Recharge Power Plus pre-charged batteries be charged for the first time (Two are on my Panasonic house phone)?
Normally the advice is to charge new batteries overnight or for like 12 hours. Have these pre-charged ones been through the first time charge so they just need to be charged full by their customers?
What happens if they are not charged fully the first time by the customer, would it shorten their lives, even though they are precharged?
What does pre-charged mean?
