OPzV Tubular Gel Batteries

OPzV batteries are sealed lead acid based. They have gelled electrolytes and tubular positive plates, which work together to deliver a superior cycle count. OPzV batteries are maintenance free and spill-proof, just like all other VRLA batteries. However, one of the most important differences between OPzV and other lead acid batteries is that, OPzV technology utilizes a very high design life of 20 years. This is thanks to the unique battery construction, which is enhanced with a positive tubular plate and a higher lead density. Other lead acid batteries are designed with flat plates, which deliver a good cycle count, but not nearly close to the cycle counts offered by OPzV. This makes them ideal for applications requiring reliable batteries that deliver many years of maintenance-free and headache-free operations.

Basic Information:

Sohigh Solar 2V OPzV series is a tubular plate gel battery that offers 20+ years of design life.

With a new design and technical improvement, it offers maximum efficiency and reliability for the widest variety of applications. This series is highly suited for all standby power applications that require the highest levels of reliability and security.

Tubular plate and Gel electrolyte make the battery a super long cycle life.

For big power bank projects, OPzV batteries could be a reliable choice, even comparing to lithium batteries.

Features and Benefits:

Safe, sealed Construction, and leakproof.

Maintenance Free, oxygen recombination technology.

Gel technology, fewer plate corrosion, super long cycle life.

No internal short-circuit possibility, because of the advanced AGM material, 300% increased the puncture resistance.

Heavy Duty Grids, PbCaSn alloy for plate grids, less gassing, less self-discharging.

Flame retardant ABS container, ensure the safety of energy product.

High purity raw material, ensure low self-discharge rate and long service life.
