When you receive your order from us the batteries will be almost fully charged but even so you should still charge before first use, you can skip this step if it's being fitted in something with its own always connected mains supply like an UPS system as it will complete this 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
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, ensure that after every use that you put the batteries back on charge, letting them sit in a partially discharged state is not wise, we have heard of people trying to extend battery their life by running them down, this will not work with this type of battery so do not try it, it will only shorten the life costing you money in the long run, 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
