The batteries that you obtain from us will be almost fully charged, but you should still charge them fully before first use, you can skip this step if the battery is going in a device with its own always connected mains charging circuit, maybe a UPS system as this will do the job for you, there should be no need for many hours, it will probably not take very long at all, just until your charger indicates they are ready, this will of course depend on the charger capabilities, you may well be impatient and use the equipment without charging but it's worth waiting until its fully charged as it will help to extend overall life expectancy
If you are a normal user then you will probably not even notice it but it can take up to ten charges and associated use in your device before its capable of accepting a full capacity charge, this is all part of the conditioning process and quite normal, you should fully charge as soon as you can after every single use, do not leave them sitting in a semi discharged state any period unless really necessary, do not attempt to deliberately discharge the batteries, it will not rejuvenate them, it will only do them harm and will reduce the life span, if for any unforeseen reason they are not being used make sure they are fully charged first, then recharge every four weeks but do not leave on the charger for more than 24-hours
