Why does the accumulator expand and deform during use?

Battery shell material is ABS material, with a vent hole at the top in battery design, battery heating will be internally expansion, expansion after the battery inside the air exhaust hole with smooth discharge. After the cooling air enters the exhaust hole like the inside of the storage battery, battery apparatus, battery at the top of the exhaust hole if blocked, the air does not come out, will cause the battery shell deformation, so the top of the battery cover is strictly prohibited
Battery during use, the user should monthly to battery maintenance. Deep discharge of the battery, the discharge should be on duty or equipment monitoring, each discharge to ensure that the battery has 10%-15% of the remaining power, can not be emptied. After the completion of the discharge of battery rest for 30--60 minutes, then do not charge, users may have doubts, why not rechargeable, this is the theme of this article, Yuasa battery shell in the process of using why expansion deformation? The battery is very hot after the discharge of high current. If it is charged, the internal temperature of the battery will be increased to uncontrollable range, so the battery should be stationary for a period of time, and then the battery will be charged.
Every time after the battery discharge to replenish energy, help for the life of the battery, can guarantee the normal operation of electric power equipment.
