The normal use of hot impact battery operation?

Does the Panasonic battery run hot and affect normal use?
Our staff survey found several customers who buy our products, some customers reflect the car battery hot, but this is all right, when the battery is in charging and discharging process of Panasonic in, because the current car battery is relatively large, and there are some Matsushita Battery battery internal resistance, Matsushita will produce a certain amount of heat, the temperature will rise. However, when the car battery charging current is too large, enhancement of Matsushita Battery room space is too small will make the charging current and lead-acid battery temperature had a cumulative, and the damage caused by thermal runaway car battery. Especially when the charging equipment used by the user is an AC power source, the charging device is filtered, but there is still ripple voltage. The AC impedance of a fully charged car battery is very small, even very small changes in the battery voltage line will produce alternating current obviously, the rise of the temperature of the battery car battery, Matsushita Battery thermal runaway lead to rising temperatures, Matsushita Battery shell strength decreased so that the softening caused by car battery under internal pressure. And cause, Matsushita Battery damage, in the correct use, generally does not affect the use of the.
