2V Dry Cell Battery:
A 2V dry cell battery is a sealed, maintenance-free lead-acid battery designed for deep-cycle applications. Unlike flooded batteries, it uses a gel or AGM (Absorbent Glass Mat) electrolyte, making it spill-proof, vibration-resistant, and ideal for solar storage, UPS systems, and telecom backup.
Key Features & Benefits
✔ Long Lifespan – 8-12 years with proper care
✔ Deep Discharge Capability – Up to 50-80% DoD (Depth of Discharge)
✔ Maintenance-Free – No water refilling required
✔ Safe & Stable – No acid leaks, minimal gas emission
✔ Wide Temp Range – Performs in -20°C to 50°C
✔ Modular Design – Connect in series/parallel for higher voltage/capacity
