Low-Voltage Battery (12 V)
The 2 poles of the low-voltage battery
are positive terminal ("+") and negative
terminal ("–").
●
To prevent the SOC of the low-
voltage battery becoming too low,
the intelligent charging function
is triggered automatically when
conditions are met (ignition o󽗈, high-
voltage battery discharging allowed,
and low-voltage battery level below
the design value).
●
If the battery voltage is too low, it may
not be able to power on the vehicle. In
that case, contact the BYD authorized
dealer or service provider promptly.
●
Check the conditions of the low-
voltage battery once a month,
including corrosion of its poles. If the
poles are corroded, disconnect the
negative terminal and pour soda water
on it. When the bubbles dissipate, rinse
the brown water and wipe them with
a dry cloth. Apply some grease to
prevent further corrosion.
●
If the connector becomes loose,
tighten the clamp nut, but do
not overtighten it. Tighten the
pressing tool until it securely 󽗉xes
the low-voltage battery in place.
Overtightening will damage the
battery box.
REMINDER
●
It is normal that intelligent
charging with the ignition o󽗈
produces a noise similar to when
the ignition is switched on.
●
Do not carry out maintenance
work during intelligent charging.
●
When leaving the vehicle, make
sure the doors are closed and all
electrical equipment is turned o󽗈.
REMINDER
●
If the vehicle needs to be parked
for a long time, please disconnect
the negative terminal wire.
CAUTION
●
When checking the low-voltage
battery, remove the ground cable
from the negative terminal (-) 󽗉rst,
and reconnect it last.
●
When cleaning the low-voltage
battery, make sure to avoid any
󽗊uid getting inside.
WARNING
●
The low-voltage battery contains
a corrosive solution. To prevent
damage to the battery or injury,
do not disassemble or repair the
battery without authorization.
●
Do not disassemble or dismantle
the low-voltage battery. Any
organization or individual to do
so shall bear the responsibility
for environmental pollution or
accidents.
●
Since the low-voltage battery
may produce combustible and
explosive hydrogen gas, use tools
in such a manner that the battery
would not produce sparks. Do not
smoke or use open 󽗊ames near
the battery.
●
Avoid electrolyte contact with
eyes, skin or clothing. In case
that happens, use baking soda
water to clean the skin, and
plenty of water to rinse the eyes,
and immediately seek medical
attention.
