The batteries you receive from us will be almost fully charged, but you should still charge them before first use, if you are using the battery in something like a UPS system you can skip this step as it will complete the charge for you after installation automatically, and do a far better job of it than you could do manually, the charger will have LED lights which will indicate whether it is still charging or not, you only need to charge them until they are ready, probably not very long at all, do not be impatient, wait until this first charge has completed before using the equipment, it will contribute to overall battery life
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, after you have used your more portable equipment you should get a charge back into it as soon as you are able, do not leave it sitting around in a partially discharged state for any longer than absolutely necessary, do not attempt to deliberately discharge the batteries, it will not rejuvenate them, it will only do them harm and will reduce the life span, it is important to keep a charge in the batteries for long life, so if there is any period of time where they are not being used then charge before hand and top this up every four weeks but do not leave on a charger for more than 24-hours
These 12-volt batteries are valve regulated and AGM or absorbed glass mat, not need for any liquid as the acid is held within the glass mat, this means they will not spill and not-hazardous so safe for use around the home and or portable equipment, they are deep cycle which would be required in this sort of application
