When you receive the order you will note that the batteries will be almost fully charged, but you should still complete a charge 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, you only need to charge until the LED on the charger indicates that its ready, it probably will not take very long at all, it is very important so not a step you should overlook, you might just want to use them, but that would be unwise, unless as stated above, missing out on charging them first could shorten 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, you should fully charge as soon as you can after every single use, do not leave them sitting in a semi discharged state for any period unless really necessary, never go out of your way to deliberately discharge fully, this will not reset them, only reduce overall life span, they may be protracted periods where the batteries are not being used, if this is the case ensure they are fully charged first, then top up every four weeks but do not leave on a charger for more than 24-hours
These 12-volt batteries are sealed lead valve regulated or VRLA and further benefit from using AGM technology, this means they will not spill so can be used indoors or in portable equipment without fear of leakage, capable of deep cycling as would be essential in this type of application, they are not hazardous
