The production date of Tianneng battery in 2022 We can find a serial number from the surface of the battery, and we can know the specific production date through the number. For example, the first six digits of the number are "220506", which means that the production date of the battery is May 6, 2022.
Buying batteries is the same as when we usually buy things, we try to choose the production date as close as possible, so that the performance of the product will not be greatly reduced. If the production date is too long, it should be a stock product, and the performance of the product will be reduced. Try to choose batteries produced within the last year or two, so that you can use them more at ease.
Most of Tianneng batteries are lead-acid batteries, and very few are lithium batteries. The charging methods of lead-acid batteries and lithium batteries are somewhat different. The first to third charging of the lead-acid battery needs to be fully charged, and the charging time is best controlled within 8 to 11 hours. After the fourth and subsequent charging, the charging time is 6 to 8 hours, which is good for the battery. relatively friendly.
We charge the Tianneng battery. When the light of the charger changes from red to green, there is no need to disconnect the power supply at this time, but continue to charge for 1 to 2 hours. The longest charging time should not exceed 11 hours, and more than 11 Hours, the battery life will be greatly affected.
The service life of Tianneng battery is generally 2 to 3 years. The battery has been used for half a year. We can deeply discharge the battery every 1 month, and then recharge it after discharge, which will have a positive effect on the recovery of the battery's power. Great positive impact.
