A regular battery, also known as a lead-acid battery, has electrodes composed of lead and lead oxides, and the electrolyte is an aqueous solution of sulfuric acid. The important advantages are stable voltage and affordable price; The disadvantage is frequent daily maintenance. Old style ordinary batteries generally have a lifespan of about 2 years and require regular checks of the electrolyte height and the addition of distilled water.

The biggest characteristic of maintenance free batteries, as the name suggests, is maintenance free. Do not replenish distilled water during its service life. It also has the characteristics of shock resistance, high temperature resistance, small size, and small self discharge. Of course, relatively speaking, its price will also be more expensive than ordinary batteries. As for the service life, the recommended replacement cycle for maintenance free batteries under normal circumstances is about 3 years.

Electric vehicle batteries are generally lead-acid batteries, which can be used normally for about 2 years, depending on personal driving habits. To prevent misleading usage and charging, the charging demand should be determined based on the electricity consumption. The method is as follows: when 100% of the battery is used up, the charging time is generally 8-10 hours, not exceeding 12 hours (which will affect the battery life). It is not recommended to use up the battery every time, and it is generally recommended to charge at around 70% of the electricity consumption. At this time, the charging time is generally 6-8 hours. If you are on a short trip, it is recommended to charge once a week when the daily electricity consumption is 10%.

When the daily electricity consumption is 20%, it can be charged once every three days. When the daily electricity consumption is 30%, it can be charged every two days. When the daily electricity consumption is above 40%, it can be charged once a day. Control the charging time, usually around 6 hours. Prevent prolonged non charging after discharge. When not in use for a long time, it is necessary to ensure that the battery is fully charged before use, and it is generally recommended to recharge the battery within 2-3 months. If conditions permit, it is best to charge it once every 1-2 months; When electric vehicles are not in use, they need to be stored in a ventilated and cool indoor environment. After the battery pack is fully charged, the load line should be disconnected. Due to the self discharge of lead-acid batteries, it can cause sulfation. If not recharged for a long time, it will be difficult to recover the capacity and affect the lifespan. Therefore, it is generally recommended to recharge the battery within 2-3 months to improve its lifespan. The current after-sales methods in the market: The warranty period provided by battery manufacturers to distributors is generally 15 months, with a period of 8 months for the first and 7 months for the second. Due to quality issues with the battery itself, new batteries are replaced within 8 months, turnover batteries are replaced within 9-11 months, and maintenance batteries are replaced within 12-15 months. At present, in the secondary market, the warranty period for users is generally one year, because there is a certain cycle from the factory to the dealership and then to the repair shop.

The lifespan of a battery is generally around 2-3 years, and if used and maintained properly, it can last for more than 4 years. If used and maintained improperly, early damage can occur within a few months. During use, the height of the electrolyte should be regularly checked, and the storage condition of the battery should be checked and replenished in a timely manner. The maintenance of batteries is relatively simple. By doing a good job in supplementing the electrolyte, cleaning the battery and pole piles, and controlling the specific gravity of the battery, the service life of the battery can be effectively extended.
