12V 7Ah Yamada lead acid battery
YAMADA lead-acid batteries with excellent reliability, in AGM (Absorbed Glass Mat) technology with internal gas recombination, without emissions of acid vapors both in buffer use and in cyclic use, for example, portable equipment. This battery does not require maintenance as it is hermetic, and can be installed inside electronic equipment without further precautions, except that, in equipment with any type of lead acid battery inside, the container should not be hermetic. The single cell of each battery is equipped with a one-way safety valve, which guarantees the disposal of any internal gas overpressures, caused by incorrect use.
Thanks to the excellent characteristics of the materials used for the production of YAMADA batteries, the loss of capacity in self-discharge is very limited.
Due to the construction characteristics of the YAMADA batteries, their use is intended purely for the safety and elevator sector, where large discharge currents are not required.
