About

Founded in 2002, Ritarpower is a private headquartered in Shenzhen, China with approximately 5000+ employees specializing in Solar, Wind, Energy Storage.

Ritar International Group has been manufacturing battery energy storage systems (BESS) since 2002. The company provides comprehensive energy storage solutions across multiple chemistries: lithium iron phosphate (LiFePO4) batteries with 10-15 year design life and up to 6,000 cycles at 80% depth of discharge; advanced AGM (Absorbent Glass Mat) batteries featuring sealed, maintenance-free operation; and proprietary solid-state OPzV tubular batteries for grid-scale applications. Products range from 12V to 800V systems and serve residential solar, commercial and industrial energy storage, telecom backup power, data center energy management, railway applications, and motive power. The company maintains state-of-the-art automated production facilities and distributes globally through 11 international logistics centers. All lithium systems are certified to UL1973, UL9540A, and IEC62619 standards and feature integrated intelligent battery management systems (BMS) with IoT monitoring capabilities.

Frequently asked questions

published by the company
What types of batteries are commonly used in BESS systems?

Lithium-ion batteries, lead-acid batteries, and flow batteries are the most common types used in BESS. Lithium-ion is preferred for high energy density and fast response, while lead-acid is more cost-effective for stationary applications.

How long do BESS batteries typically last?

The lifespan depends on battery chemistry, usage, and environmental conditions. Lithium-ion batteries typically last 10–15 years, while lead-acid batteries last around 3–7 years under normal operation.

Can BESS batteries be safely used for residential and commercial applications?

Yes. Modern BESS batteries are designed with advanced safety features, including thermal management, overcharge protection, and battery management systems (BMS), making them safe for both residential and commercial energy storage applications.

How does an AGM battery differ from a standard Flooded battery?

The primary differences lie in the internal structure and maintenance requirements: Maintenance: AGM batteries are maintenance-free and sealed; flooded batteries often require water topping. Vibration Resistance: The compressed mat design of AGM makes them much more durable in high-vibration environments. Mounting: AGM batteries can be installed on their side or at various angles (except upside down) because they won't leak. Flooded batteries must remain upright.

Can I use a standard charger for my AGM battery?

No, it is not recommended. AGM batteries are sensitive to overcharging. Standard chargers designed for flooded batteries often use higher voltages that can "cook" the electrolyte in an AGM battery, leading to premature failure. You should use a "smart" charger with a dedicated AGM setting that regulates the voltage precisely (typically around 14.4V to 14.6V for charging and 13.5V to 13.8V for floating).

What are the main advantages of AGM technology?

Faster Charging: AGM batteries have low internal resistance, allowing them to accept a charge up to five times faster than flooded batteries. High Cranking Amps: They are excellent for "Start-Stop" vehicle technology because they can deliver high bursts of power. Low Self-Discharge: They lose their charge very slowly when sitting idle, making them ideal for seasonal vehicles (like motorcycles or boats). Deep Cycle Capability: They generally handle deeper discharges better than standard starting batteries.

Are AGM batteries the same as Gel batteries?

No, though they are both sealed VRLA batteries. AGM uses a fiberglass mat to hold liquid acid. Gel uses a silica additive to turn the electrolyte into a thick, jelly-like paste. AGM batteries are generally better for high-current applications (starting engines), while Gel batteries are often preferred for very deep, slow-discharge solar applications.

How long do AGM batteries typically last?

Under ideal conditions, a high-quality AGM battery can last 6 to 10 years. However, lifespan is heavily dependent on: Depth of Discharge (DOD): Consistently discharging the battery below 50% will shorten its life. Temperature: Excessive heat is the "number one killer" of AGM batteries, as it accelerates chemical degradation.

Why are AGM batteries more expensive?

The cost is higher due to the premium materials (high-purity lead and fiberglass mats) and the more complex manufacturing process required to ensure the cells are compressed and sealed perfectly. Most users find the extra cost is offset by the longer lifespan and lack of maintenance.

Do AGM batteries need to be vented?

While they are "sealed," they still have safety valves (VRLA) designed to release pressure if the battery is severely overcharged and gas builds up. Because of this, they should still be kept in a space with some ventilation and should never be placed in a completely airtight container.

What exactly is an AGM battery?

An AGM battery is a type of Valve Regulated Lead Acid (VRLA) battery. It uses a special Absorbent Glass Mat—a thin fiberglass mat saturated with electrolyte—sandwiched between the lead plates. This design keeps the electrolyte in a "dry" or suspended state rather than liquid form, making the battery spill-proof and highly vibration-resistant.
