iSecure 12V20A is a 12V200Ah deep cycle battery that designed to have a large amount of stored current discharged between charging sessions, with very heavy non-porous battery plates to withstand repeated major discharging and charging cycle(deep cycle). It uses a different chemistry for the plates active paste material, and a slightly stronger electrolyte than normal battery electrolyte, which allows for a much longer life in deep cycle applications like E-bike, Emergency Power System, Power tools, Solar and Wind Power System, Cable Television and more.
