Description

12V 200AH GEL Battery

Voltage: 12V means the nominal voltage of the battery is 12 volts. This is the average voltage of the battery when it is fully charged and running under load.

Capacity: 200Ah means that when the capacity of the battery is 200 amperes, the battery can provide a continuous discharge current of 1 hour under certain conditions. Capacity is used to measure the ability of a battery to store electrical energy. Generally speaking, the larger the capacity, the more electrical energy the battery can provide.

Gel battery: Gel battery (Gel Battery) is a variant of lead-acid battery. Silicone or other colloidal substances are added to the electrolyte to make the electrolyte viscous. This design can reduce the liquid evaporation and leakage risk of the battery, and enhance the deep discharge resistance and cycle life of the battery.

What Is Deep Cycle Battery ?

Deep cycle batteries are designed to provide a steady output of electrical energy over charge and discharge cycles and have the following characteristics:

Cycle Life: It has a long cycle life and can withstand multiple deep discharge and charge cycles. Deep cycle batteries are usually designed with heavy lead and electrolyte to provide more energy storage and better cycle stability.

Deep Discharge Capability: The ability to be discharged to a relatively low charge level per cycle. Relative to a starter battery, a deep cycle battery can be discharged more deeply without a serious impact on battery life.

Low Self-Discharge Rate: A relatively low self-discharge rate allows deep-cycle batteries to maintain high charge levels during long-term storage or idle periods. This means that even when the battery is not being used, it is able to maintain some electrical energy storage.

10 Hour Rate Battery:

10-Hour Rate is a standard used to evaluate battery capacity. It indicates the continuous discharge current that the battery can provide within 10 hours, usually expressed in ampere (A).

For example, if a battery has a 10-hour rate of 100Ah, it means that the battery can supply 100 amps when discharged continuously for 10 hours. According to this standard, the current output at other discharge times can be deduced.

The 10-hour rate is a common standard used to compare the capacities of different batteries. Usually, the actual capacity of a battery is affected by temperature, discharge rate and other conditions, so the exact capacity may vary in actual use.

In addition to the 10-hour rate, there are other evaluation standards under discharge time, such as 20-hour rate, 5-hour rate, etc., which can be used to more accurately evaluate the battery capacity under different conditions. Selecting a discharge time rate that suits the needs of a particular application can help determine the correct size and capacity of the battery.

The difference between GEL battery (Gel Battery) and AGM battery (Absorbent Glass Mat Battery):

Construction: GEL batteries use silica gel (Gel) as the electrolyte, solidify the electrolyte into a gel, and inject it between the separator and the plate in the battery. AGM batteries use glass fiber battery separators (Absorbent Glass Mat) to absorb and retain electrolyte, and the gap between these separators and electrodes is filled with electrolyte.

Solidification of electrolyte: The electrolyte of GEL battery is gel-like, with good stability and anti-leakage performance, even if the battery case is damaged, it will not leak. The electrolyte of the AGM battery is adsorbed on the glass fiber separator, has a higher electrolyte content, and is relatively more prone to leakage.

Life and cycle characteristics: Since the electrolyte of the GEL battery is gel-like, its electrolyte fluidity is relatively poor during the cycle, so it has strong resistance to overcharge and over-discharge, and is more suitable for long-term deep cycles. AGM batteries have better electrolyte fluidity during cycling, and respond faster to transient high current discharge and charge, so they are more suitable for high discharge demand and start-up applications.

Charging characteristics: GEL batteries have strict requirements on charging voltage and charging current, and require specific charging control. AGM batteries are relatively more tolerant to charging conditions and can accept higher charging currents.

Cost: In general, GEL batteries are expensive to manufacture because of the need for gelled electrolytes in the manufacturing process, while AGM batteries are relatively inexpensive to manufacture.

Depending on the application requirements and usage conditions, the choice of GEL battery or AGM battery will be different. GEL batteries are commonly used in solar systems, electric vehicles, ships and other applications that require stable cycle performance and require leak resistance. AGM batteries are often used in application scenarios that require high discharge capacity and fast response, such as car starting batteries, car audio systems, and emergency power backup.
