The batteries will be delivered with a very good charge in them, but even so you should still charge before using for the first time, if the battery is being fitted in something like an UPS system then you can miss this step as the on board circuit will do a better job of charging it than you, just charge them until your charger LED lights indicate that it is ready, it will probably not take very long, do not be impatient, wait until this first charge has completed before using the equipment, it will contribute to overall battery life
it may well take up to ten charges and alternating use in your equipment for the battery to fully condition and be able to take a full capacity charge, this is all quite normal, as soon as you after each use put them back on charge, do not allow them to sit in a discharged state, do not try to fully discharge the batteries, it will not rejuvenate them, it will reduce the lifespan and cost you money in the long run, if not using them recharge every 4 to 6-weeks but do not leave on the charger for more than 24-hours at a time
