How to classify lithium 3400mah 3.7v 18650 battery and how to disassemble them?
lithium 3400mah 3.7v 18650 battery are classified into ordinary batteries, dry-charge batteries and maintenance-free batteries. The voltage is relatively stable and the price is relatively cheap. In addition, the disassembly method of the car battery is to disassemble the positive connector: use the same method to disassemble the positive connector; next Let me introduce the details to you.
1. Classification of lithium 3400mah 3.7v 18650 battery
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 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 liquid, 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. There are also two types of maintenance-free batteries on the market: the first type requires a one-time addition of electrolyte when purchased and does not require maintenance (adding replenishing fluid) during subsequent use; the other type is that the battery itself has electrolyte added and sealed at the factory. , the user cannot add refill fluid at all.
2. How to disassemble the car battery
1. Loosen the nut of the negative electrode connector: Open the two fixing buttons of the insulation cotton, and you can see the two red and black insulation covers on the positive and negative electrode connectors. Open the insulation cover and you can see the locking nut;
2. Disassemble the negative electrode connector: Use a wrench or hex socket to unscrew the fastening nut of the negative electrode, then use a flat-blade screwdriver to slowly pry open the fastening block, and then pull out the negative electrode connector;
3. Disassemble the positive connector: Use the same method to disassemble the positive connector;
4. Disassemble the locking strap: Unscrew the nut used to fix the battery's locking strap, loosen the locking strap, and then take out the battery.
5. When installing a new battery, just follow the reverse steps. However, it should be noted that the order of installing the positive and negative connectors is "positive first, then negative", which is opposite to that of disassembly. The principle is the same, both to prevent the risk of short circuit and ensure safety.
