When you receive your order from us they will have a fairly high charge in them, but you still need to fully charge them before first use, this will not be necessary only if being fitted in something that is always connected to the mains like a UPS system which will do this job for you, the time of the first charge will be dependent on the charger, just leave it on until its finished, it will probably not take very long, while you may well be tempted just to use them without charging first, if it's going in a portable device or mobility electric vehicle it would be unwise to miss this out
Most users will not even notice but it will take a number of charges and associated use in your equipment before they are capable of accepting a full capacity charge, this is quite normal and part of the conditioning process, each time you have used your battery then recharge as soon as you can, do not leave it sitting in a semi discharged state, do not attempt to discharge the batteries fully, this will defiantly not extend the life of them, quite the contrary, with this type of technology it will only reduce life span quite drastically so cost you money in the long run, If there are extended periods where the batteries are not being used then ensure they are fully charged beforehand then recharged every four weeks but you should not leave on the charger for more than 24-hours
