When place your and receive an order you will note that the batteries will be almost fully charged when received, but you should still complete a charge before first use, this will not be necessary only if being fitted in something that is always connected to the mains like an alarm system which will do the job for you, it shouldn't take long, just until the charger lights indicates its ready, if really in doubt overnight will be more than enough but it's doubtful you would need to leave it on the charger that long, you may well be impatient and use the equipment without charging but it's worth waiting until its fully charged and will help extend overall life expectancy
It's not always apparent but it will take up to ten charges combined with use in your chosen device before a full capacity charge can be achieved, this is just a normal part of the conditioning process, when you have used your portable devices then put the batteries back on charge, you do not want to allow them to sit in a partially discharged state, never go out of your way to deliberately discharge fully, this will only reduce overall life span, there may well be extended periods where the batteries are not being actively used, if so ensure they are charged fully beforehand and then recharged every 4 to 6-weeks but do not leave on the charger for more than 24-hours at a time
