Do not mix and match new and old batteries with 12V12AH

  Batteries have been widely used in our time, and batteries in household appliances and automobiles have also been widely used. Batteries play a very important role in our era. We all know that to replace all batteries with old batteries, we must never mix old batteries with old batteries.

  Because people don’t know much about the use of batteries, there will be more or less errors when using batteries, such as using new and old batteries in series, but I don’t know this Will this shorten the life of the new battery?

  The new battery has more chemical reaction substances, higher terminal voltage and smaller internal resistance, while the old battery has a lower voltage and larger internal resistance. The internal resistance of a new 12V battery is generally 0.015 ≤ 0.018 ohms. The internal resistance of the old battery is greater than 0. 085 ohms. If the new and old batteries are used in series, the charging voltage at both ends of the old battery will be higher than that of the new battery under the charging state. Charging voltage. The results showed that the new battery did not overflow, and the old battery was already very high, but in a discharged state. Because the battery capacity was larger than the old battery, the old battery was over-discharged and even the old battery was turned upside down. The swelling of the battery will have side effects. It will lose the power of the new battery, and it will also form an electrical appliance with unstable internal voltage. At the same time, there is a risk of overusing the old battery.

   Old and new batteries cannot be confused. Mixing and matching can not only save electricity, but also waste electricity, resulting in very small losses. Contact: 18038382979
