What is the difference between gel batteries and lead-acid batteries? Who is good?

Lead-acid batteries are generally: 4-5 years; colloidal batteries are generally: 12 years. 2. The use environment is different. Generally, the working temperature of lead-acid batteries cannot exceed minus 3°C. Gel batteries can work at minus 30°C. 3. Safety Lead-acid batteries have acid creeping phenomenon, and improper management will cause explosions. Gel batteries have no acid creeping phenomenon and will not explode. 4. Lead-acid battery specifications are less than gel batteries. Lead-acid battery specifications: only 24AH, 30AH, 40AH, 65AH, 100AH, 200 six specifications; gel battery specifications: from 5.5Ah, 8.5Ah, 12Ah, 20Ah, 32Ah, 50Ah, 65Ah, 85Ah, 90Ah, 100Ah, 120Ah, 165Ah, 180Ah, 12 specifications, which can meet most of the needs, to prevent the battery capacity caused by the small specifications from being larger than the actual demand, and the battery will be damaged by the small current discharge during discharge The plates are damaged. Gel battery 5. Electrolyte adsorption technology: The gel battery adopts the colloidal adsorption technology: (1) The inside is gel electrolyte, and there is no free electrolyte phenomenon. (2) The electrolyte has about 20% capacity margin, so it is still extremely reliable in high temperature operation or overcharging, and the battery will not dry out. The battery has a wide range of high and low temperatures. (3) The upper and lower concentrations of the colloidal electrolyte are the same, and there will be no acid stratification. Therefore, the reaction is uniform, and in the case of high-rate discharge, the plate will not be deformed and cause internal short circuit. (4) The specific gravity of the acid is low, (1.24), the corrosion of the electrode plate itself is relatively low. The low-lead-acid battery uses glass wool adsorption technology: (1) The acid is absorbed in the glass blanket, and there is a large amount of free electrolyte. exist. It is likely to leak under strong charging conditions. (2) The amount of electrolyte is less than 20% (lean acid state), so the reliability is low during high temperature operation or overcharging, and the battery will inevitably dry out. (3) Due to the deposition of the liquid electrolyte, there is a difference in the upper and lower concentrations (acid stratification phenomenon, and the acid stratification is irreversible), so the reaction is uneven, and the electrode plate is deformed during high-rate discharge, and even breaks down the plate. Internal short circuit. (4) The specific gravity of the acid solution is high, (1.33), and the corrosion of the electrode plate itself is relatively large. 6. Comparison of the positive electrode of the gel battery and the lead-acid battery The positive electrode plate of the gel battery is a high-quality cake-free alloy, and the self-discharge rate is extremely low. At 20°C and normal temperature, the self-discharge rate is less than 0.05% per day, and it still maintains 50% of the original capacity after two years of storage. The general lead-calcium alloy plate of lead-acid battery has a high self-discharge rate. Under the same circumstances, it must be recharged after storage for about 6 months. With longer storage time, the battery will face the possibility of damage. 7. Comparison of the protection of gel batteries and lead-acid batteries. Gel batteries have a deep discharge protection mechanism inside, and the batteries after deep discharge can still be connected to the load. Charging within four weeks will not damage the performance of the battery. The nominal capacity of the battery will be restored soon after being charged, and the battery life will not be affected.
