The batteries that you obtain from us will be almost fully charged when delivered, but you should still charge them fully 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
If you are a normal user then you will probably not even notice it but it can take up to ten charges and associated use in your device before its capable of accepting a full capacity charge, this is all part of the conditioning process and quite normal, recharge after each use, do not let them sit in a partially discharged state for any longer than absolutely necessary, you cannot rejuvenate this kind of battery by running them down, going out of your way to do so will shorten its life and cost you money, if there are extended periods where you are not using the batteries actively then fully charge before putting them away and again every six weeks, do not leave on the charger for more than 24-hours at a time
The battery type is AGM which is short for absorbed glass mat construction, they are also valve regulated, they means they can be used around the home or in portable devices without the fear of any leakage, with deep cycle properties that this type of installation would require, they will require no maintenance throughout their entire life span and are not hazardous
