This AGM type battery does not need any outside maintenance, except of course charging, the nasty acid, familiar to many is safely contained within a glass mat between the plates so will not leak out if laid on its side, it is not-hazardous so can be used indoors and indeed often used in portable devices.

This new 12v battery pack will be delivered to you almost fully charged when you receive it. Still, unless it's going in a device with its own always-powered mains-connected charging circuit like a UPS system, then it will still require that critical first charge before use, also charge after every single use, do not try to run it down deliberately, this will only shorten its life and if not being used for long periods then also every four weeks to help prolong the life expectancy, by not keeping your new battery fully charged you are risking a shorter life which will cost you money in the long run.
