Battery Type: Rechargeable sealed lead‐acid deep‐cycle battery — designed to discharge and recharge repeatedly without needing water top‐ups.
Voltage: 12 V (standard for small inverter/backup systems).
Capacity: 40 Ah (Ampere‐hours) — this rating indicates how much current the battery can deliver over time; 40 Ah means it can ideally supply 1 A for 40 hours or 2 A for about 20 hours before needing recharge.
Construction: Sealed and leak‐proof, with heavy‐duty grids and low self‐discharge for longer standby life.
Protection: Often includes overcharge and deep discharge protection, which helps extend battery lifespan.
Compact Design: Sized for easy placement in inverter cabinets or small solar setups.
