Sealake FM628 battery 6v sealed rechargeable VRLA.
Replacement Sealake FM628 battery a compact rechargeable 6v energy storage source that will not-spill so suitable for portable equipment as well as things like alarm systems and emergency lighting.

Unless the battery is going into something like a alarm system as a battery back up which has its own charging circuit then you should keep it charged, charged before first use and after each and every one, you do not want to allow it to sit in a discharged state as this will prematurely reduce the overall life if it, also if not being used for longer periods then give a little top up charge every couple of months, more frequent if stored in a cold damp place.
