How to choose Lead Acid replacement?
Solar street lights have now become the main equipment for road lighting in cities and villages. The equipment is simple and does not require a lot of wiring. By converting light energy into electrical energy, and electrical energy into light energy, it brings a piece of light to the night. In the meantime, Rechargeable and dischargeable batteries play a key role.
Compared with the previous lead-acid batteries or gel batteries, the commonly used Lead Acid replacements are better than the power and other aspects, and it is easier to achieve fast charging and deep discharge, and the lifespan is relatively long, so it also brings us good. However, there are differences in the quality of Lead Acid replacements. Let's start with their packaging forms to see what characteristics these Lead Acid replacements have, and which one is better. The packaging forms often include cylindrical winding and square stacking. There are also three types of square coils.
In short, the solar lithium battery is a cylindrical battery (cylindrical winding type), which generally uses a steel shell, and also has an aluminum shell. The process is relatively mature, small standard, active in groups, low cost, sophisticated in technology, and good in commonality; after grouping, the heat dissipation is not well planned, the weight is heavy, and the specific energy is low.
Shaped batteries (square wound type), most of them were steel shells in the early stage, and most of them are aluminum shells now. Good heat dissipation, simple design in groups, good reliability, high security, including explosion-proof valve, high hardness; high cost, many types, difficult to match the technological level, it is one of the mainstream technical paths.
