Battery short circuits may cause personal injury. The high transient current generated by a
short circuit may release a surge of power and cause fire.
To avoid battery short circuits, do not replace batteries online.

Do not use unsealed lead-acid batteries. Place and secure lead-acid batteries horizontally to
prevent inflammation or device corrosion due to flammable gas emitted from batteries.
Lead-acid batteries emit flammable gas when used. Therefore, store these batteries in
