The C rating refers to the discharge time with the C10 (10 hour discharge) rating being the most common rating used. The available energy stored in a battery is known as the battery capacity which is measured in amp hours (Ah) at a specific C rating. Battery Capacity And Depth Of Discharge (DOD) There are many well established trusted companies manufacturing high quality tubular gel lead-acid batteries for solar applications. Tubular Gel batteries can offer very high cycle life, up to 5000 cycles (15 years) at 20% DOD and 3000 cycles at 40% DOD, if the specific charging parameters are met, and the battery is maintained within the correct temperature range (usually 15-30 degC).Īdvanced tubular gel deep cycle batteries are a proven technology with 15+ year design life. The manufacturers listed below use advanced tubular-plate electrodes with woven polyester gauntlet and solid grids in a corrosion-resistant lead-calcium alloy. These are often referred to as OPzV (Ortsfest PanZerplatte Verschlossen) batteries, which is German for ‘stationary tubular plate closed’ battery.

These tubular gel VRLA single cell (2V) batteries are linked together in series to form 24V or 48V deep cycle battery banks. There are several high quality battery manufacturers which have engineered very high performance, high cycle life batteries, specifically designed for solar installations. There are several companies which manufacture lead-carbon batteries with nano carbon or advanced cathode alloy materials including Japanese manufacturers GS Yuasa and YHI Power. The REXC series Lead-Carbon batteries from Narada uses a nano carbon material cathode which the company claims also provides a much longer cycle life than traditional lead-acid batteries.

Tubular Gel OPzV Lead-Acid BatteriesMuch like the common Gel sealed batteries, lead-carbon batteries are also sealed and typically use a gel electrolyte for improved safety and low maintenance.
