In the world of lead-acid batteries, the word "tight" refers to the way the electrolyte is retained, which is mainly divided into open type (rich liquid type) and valve-regulated type (poor liquid type). The terms "small density", "medium density" and "large density" that we often refer to are a common classification of valve-regulated sealed lead-acid batteries (VRLA) within the industry. They are mainly based on the volume and structure of the batteries, and their characteristics and application scenarios also vary.

Small sealed batteries, usually referring to small sealed batteries, such as the common 12V7Ah, 12V20Ah, etc. They are small in size and mostly have ABS plastic shells, making them the most widely used category. The Xiaomi battery is designed to be easy to maintain and is affordable, but its cycle life after deep discharge is relatively short. It is mainly applied in fields such as uninterruptible power supplies (UPS), emergency lighting, electric toys, and alarm systems, where space and cost are sensitive and discharge is not very frequent.

Medium-density batteries lie between low-density and high-density ones, with larger capacity and volume, such as 12V65Ah, 12V100Ah, etc. It has been strengthened in structure, with thicker plates and more electrolyte reserves. Therefore, its cycle life and deep discharge recovery capability are superior to those of small-density batteries. Medium-density batteries are often used in small solar energy storage systems, backup power supplies for communication base stations, electric tricycles, golf carts and other medium-power scenarios that require a certain number of cycles and a relatively long backup time.

High-density batteries refer to large sealed batteries with a single cell voltage of 2V, which are connected in series to form systems of different voltages. Its core feature is the adoption of tubular positive plates, which have an extremely long float charge and cycle life (up to more than 10 years), strong seismic resistance and the most stable performance. Of course, its volume, weight and price are also the highest. Dami batteries are the absolute mainstay of backup power sources in key fields such as large data centers, financial system computer rooms, industrial control, and new energy storage power stations.

In conclusion, the choice of which type of battery to use depends on the application requirements: compact, economical and portable, suitable for daily backup; Medium-density, balanced and durable, suitable for small and medium-sized power and energy storage. The great secret is solid, long-lasting and reliable, providing a dependable guarantee for key systems.
