De-Bull Tall Tubular Battery

Product Details

The De-Bull DB-2200 Tall Tubular Battery is a high-quality, heavy-duty energy storage solution designed specifically for demanding solar and inverter applications. Engineered with advanced German tubular technology and incorporating silver calcium alloy in the plates, this battery delivers exceptional efficiency, rapid recharging, minimal water loss, and outstanding cycle life even under deep discharge conditions.

Its tall tubular plate design ensures superior deep-cycling performance, making it highly suitable for storing solar energy in off-grid setups, providing extended backup during prolonged power outages, or supporting heavy inverter loads in homes, businesses, farms, and remote locations. The silver calcium technology enhances corrosion resistance, reduces self-discharge, and allows quicker, more efficient charging while requiring far less frequent maintenance (ultra-low water topping).

This battery excels in providing sustainable, high-performance energy storage — a trusted option for solar enthusiasts and inverter users seeking durability and efficiency in challenging environments.

Key benefits include:

Prolonged backup time for inverters and solar systems
Fast and efficient recharging from solar panels or grid
Excellent deep discharge recovery without compromising lifespan
High heat tolerance, ideal for hot climates like Nigeria
Low maintenance and reduced water consumption
Robust build for reliable, long-term performance in harsh conditions

Whether you're building a solar power system, powering your home inverter during frequent blackouts, or ensuring uninterrupted energy in commercial or rural settings, the De-Bull DB-2200 provides dependable, high-capacity power with premium German-inspired engineering and silver calcium advantages for maximum reliability and value.
