Nickel Hydride No. 5 batteries

　　What are the classifications of Nickel Hydride No. 5 batteries and what should I pay attention to when adding water?

　　Nickel Hydride No. 5 batteries can be divided into: ordinary batteries, dry-charge batteries and maintenance-free batteries. The service life of maintenance-free batteries is generally twice that of ordinary batteries. In addition, when adding water, be careful not to touch the replenishing fluid with metal, and the replenishing fluid must be It is dedicated and cannot be used casually for drinking pure water. The relevant content is introduced in detail below.

　　1. Classification of Nickel Hydride No. 5 batteries

　　1. Ordinary battery

　　The plates of ordinary batteries are composed of lead and lead oxide, and the electrolyte is an aqueous solution of sulfuric acid. Its main advantages are stable voltage and low price; its disadvantages are low specific energy (that is, the amount of electrical energy stored per kilogram of battery), short service life and frequent daily maintenance.

　　2. Dry charge battery

　　Its full name is dry-charged lead-acid battery. Its main feature is that the negative plate has a high power storage capacity. In a completely dry state, it can store the power obtained within two years. When using it, just add electrolyte solution, wait 20 - 30 minutes before use.

　　3. Maintenance-free battery

　　Due to its structural advantages, maintenance-free batteries consume very little electrolyte and basically do not need to replenish distilled water during their service life. It also has the characteristics of shock resistance, high temperature resistance, small size and low self-discharge. The service life is generally twice that of ordinary batteries.

　　2. Pay attention when refilling the forklift battery

　　1. Do not open the control valve for too long. If a small current repair solution is adopted, the control valve should be closed immediately, otherwise impurities in the air will enter the battery and affect the battery life;

　　2. It is best to replenish water at the end of battery charging, so that the water can be replenished at once, and it is not easy to add too much and it is not easy for impurities to enter.

　　3. The so-called "replenishing liquid" must be dedicated, and the resistance value must be measured before use. Drinking pure water cannot be used casually.

　　4. Be sure to take good care of the control valve and keep it clean.

　　5. It is absolutely forbidden to touch the replenishing fluid with metal.

　　After each replenishment, the battery is in an overcharged state to change the battery from a 'quasi-liquid' state to a 'liquid-poor' state, and this overcharging is beneficial to increasing battery capacity.
