After placing your order and upon receipt of your new battery pack you may note that they have a good charge in them, but you should still charge them fully before using them for the first time. If the battery is being fitted in something like a UPS system then you can miss this step as the onboard circuit will do a better job of charging it than you. You do not need to leave it on for hours on end. it will probably not take very long at all depending on the charger. just until the charger has indicated that it has finished. You may well be impatient and use the equipment without charging but it's worth waiting until it's fully charged as it will help to 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. Allowing your new batteries to sit without charge is not a good idea, as soon as you have finished using them put them back on charge, you should never deliberately go out of your way to try fully discharge the batteries. It will not reset them, this will only reduce their life span and cost you money in the long run, 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 twenty-four hours.
