What are the differences between gel batteries and lead-acid batteries? Which one is better?

1. The battery life is different. Battery lead-acid battery is generally: 4-5 years; colloidal battery is generally: 12 years. 2. The battery usage 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. Battery safety. Lead-acid batteries have acid creeping phenomenon. Improper management will cause explosions. Gel batteries have no acid creeping phenomenon and will not explode. 4. Lead-acid batteries have fewer specifications than gel batteries. Lead-acid batteries have six specifications: 24AH, 30AH, 40AH, 65AH, 100AH, and 200; 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. Beware that the battery capacity caused by the small specifications is larger than the actual demand, and the battery is discharged when the discharge is small The plates are damaged. 5. Electrolyte adsorption technology: The colloidal 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 average, and in the case of high-rate discharge, the plate will not be deformed and cause internal short circuits. (4) The specific gravity of the acid is low, (1.24), the corrosion of the electrode plate itself is relatively low. The lead-acid battery adopts 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, 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 to the electrode plate itself is relatively large. 6. The 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 with extremely low self-discharge rate. 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 protection between gel battery and lead-acid battery. Gel battery has a deep discharge protection mechanism inside, and the battery 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.
