Maintenance and do-it yourself -> 12-volt battery for Your Nissan Leaf 4 Door First Generation (2010-2017)

12-VOLT BATTERY  
To fill the window washer fluid reservoir, lift the  
cap and pour the window washer fluid into the  
reservoir opening.  
• Keep the 12-volt battery surface clean and dry.  
Clean the 12-volt battery with a solution of  
baking soda and water.  
•
Pre-mix washer fluid concentrates  
with water to the manufacturer’s rec-  
ommended levels before pouring the  
fluid into the window washer reservoir  
tank. Do not use the window washer  
reservoir tank to mix the washer fluid  
concentrate and water.  
• Make certain the terminal connections are clean  
and securely tightened.  
Add a washer solvent to the washer for better  
cleaning. In the winter season, add a windshield  
washer antifreeze. Follow the manufacturer’s in-  
structions for the mixture ratio.  
NOTE:  
Care should be taken to avoid situations  
that can lead to potential battery discharge  
and potential no-start conditions such as:  
Fill the window washer fluid reservoir periodically.  
Refill the reservoir more frequently when driving  
conditions require an increased amount of win-  
dow washer fluid.  
1. Installation or extended use of electronic ac-  
cessories that consume battery power when  
the engine is not running (Phone chargers,  
GPS, DVD players, etc.)  
Recommended fluid:  
Genuine NISSAN Windshield Washer Concen-  
trate Cleaner & Antifreeze or equivalent  
2. Vehicle is not driven regularly and/or only  
driven short distances.  
In these cases, the battery may need to be  
charged to maintain battery health.  
CAUTION  
•
•
Do not substitute anti-freeze coolant  
for window washer solution. This may  
result in damage to the paint.  
Do not fill the window washer reservoir  
tank with washer fluid concentrates at  
full strength. Some methyl alcohol  
based washer fluid concentrates may  
permanently stain the grille if spilled  
while filling the window washer reser-  
voir tank.  
WARNING  
•
Do not expose the 12-volt battery to  
flames or electrical sparks. Hydrogen  
gas generated by the 12-volt battery is  
explosive. Do not allow 12-volt battery  
fluid to contact your skin, eyes, fabrics  
or painted surfaces. After touching a  
12-volt battery or 12-volt battery cap,

do not touch or rub your eyes. Thor-  
oughly wash your hands. If the acid  
contacts your eyes, skin or clothing,  
immediately flush with water for at  
least 15 minutes and seek medical at-  
tention.  
Do not operate the vehicle if the fluid  
in the 12-volt battery is low. Low 12-  
volt battery fluid can cause a higher  
load on the 12-volt battery which can  
generate heat, reduce battery life, and  
in some cases lead to an explosion.  
When working on or near a 12-volt  
battery, always wear suitable eye pro-  
tection and remove all jewelry.
