A usually common automatic charger
Item
A patent Zubora automatic charger
It is used only outside the machine. No
consideration has been paid for the inside-
use from the beginning.
Designing
Concept
It is used both outside and inside the machine. In the case of the outside-use, it can be suspended either inclined or vertically and also on the machine.
With no consideration except for a
commonsense shock
Shock proof
From the beginning anti-shock measures were taken into account. It stands for the acceleration of 2G and for the vibration of XYZ3 direction.

Over-current protection with a fuse which
needs to replace when damaged.
Over-current
protection
Over-current protection with a semiconductor return
There is a small LED (Light Emitting Diode)
in light indicating when charging is not
progressing, but most people do not notice
of this, simply believing that it is going on
because a battery is connected with a
charger.
Reverse
connection
Although there is no big Light Emitting Diode equipped, there is an electronic alarm system giving sounds when charging is not progressing. So everyone can be aware of this and reconnect both a battery and a charger correctly.
It is necessary to attach a meter when
charging is done.
Most types are not suitably designed to
install in a machine (a vehicle).
Others
There is no worry about ignition and fire. Also, neither unloading of a battery nor opening a cap is necessary when charge is done.
The life of this charger is so long maybe 100 years if it is correctly used.
