Full-liquid Lead-acid (wet Battery) Batteries Are One Of The Mo

  •   What is a "lead-acid dip" battery

      Full-liquid lead-acid (wet battery) batteries are one of the most common battery types in deep cycle applications. The main difference between a wet battery and a closed battery is that the end-user can replenish the water lost due to deflation through the exhaust cap on the top of the battery. A fully charged battery has been around for a long time, but it is still popular because it strikes a good balance between price and performance. The price of a gel or AGM battery is usually about twice the price per ampere hour of a fully charged battery. A fully charged battery does require more maintenance than a sealed lead-acid battery, because the battery is not a recombined battery, and moisture will be lost through the top of the vent cover when charging. Replacing this lost water can sometimes be an onerous task.

      What is a "sealed lead acid" battery (VRLA)

      Sealed lead-acid batteries are often referred to as "maintenance-free" or valve-regulated. In a sealed lead-acid battery, the device is sealed, which means that water loss can be kept to a minimum, and you don’t need to add any water to the battery. Most sealed VRLA batteries are recombined, which essentially means that the water lost through the discharge of hydrogen and oxygen in the overflow battery is the most common sealed lead-acid battery or SLA battery we carry, namely AGM (absorbent glass mat ) Battery; the other is a GEL type battery.

      AGM battery has a very thin borosilicate glass pad between the inner plates of the battery. About 95% of the mat is full of electrolytes, rather than fully saturated. The significant advantage of such batteries is that they can be operated in almost any direction, and can even be used underwater. Even if pierced, they will never leak.

      The electrolyte of the Sealed Maintenance Free Battery is stored in gel form; even if the battery is broken, it will not overflow, and it can also prevent other types of batteries from delamination. However, gel cells do have some limitations. Their charging speed is slower than that of an AGM battery of the same size. If overcharged, voids may form in the gel, permanently reducing battery capacity.

      However, for deep-cycle applications, the price of sealed lead-acid batteries is much more expensive than similar water-immersed lead-acid batteries. However, sometimes a sealed battery will meet your needs better than a fully charged battery. Especially in marine applications where stability is not always stable and ventilation space is difficult to obtain, it is usually suitable for sealing lead-acid batteries. Another advantage of AGM and Gel batteries over flooded batteries is the low self-discharge rate. If a full-filled battery will lose about 13% of its power in one month, AGM or Sealed Gel Battery will lose 1%-3%.
