Nissan Armada battery location and maintenance overview

Basic information

On the Nissan Armada, batteries labeled "do not open" are fully maintenance-free, meaning the internal electrolyte level does not require inspection. For accurate diagnostics and performance checks, it is strongly recommended to consult an authorized NISSAN dealer or a qualified technician.
To ensure reliable operation of your Nissan Armada, always keep the battery housing clean and dry. If necessary, gently clean the surface using a mixture of baking soda and water to neutralize any corrosion.
Inspect the battery terminals regularly. Make sure all connections are tight, corrosion-free, and securely fastened to maintain optimal electrical flow in your Nissan Armada.
If the Nissan Armada will remain unused for an extended period (30 days or longer), disconnect the negative terminal battery cable to prevent gradual discharge and preserve battery life.

NOTE:

To maintain battery health in your Nissan Armada, avoid conditions that may lead to battery drain or starting issues, including:

1. Prolonged use or installation of electronic devices (such as phone chargers, GPS systems, or entertainment equipment) when the engine is off.

2. Driving the Nissan Armada infrequently or only for short distances, which may not allow the battery to fully recharge.

In such situations, periodic battery charging is recommended to maintain proper performance and extend service life.

WARNING

Never expose the Nissan Armada battery to open flames or sparks.

The battery emits hydrogen gas, which is highly explosive. Avoid contact between battery fluid and skin, eyes, fabrics, or painted surfaces.

After handling the battery or its cap, do not touch your eyes.

If contact occurs, wash hands thoroughly. In case of acid exposure, immediately rinse the affected area with water for at least 15 minutes and seek medical attention.
Always wear appropriate eye protection and remove jewelry when working near the Nissan Armada battery.
Battery terminals contain lead and lead compounds. Wash hands thoroughly after handling.
Keep the battery out of reach of children at all times.
Never tilt or invert the battery.

Variable voltage control system

CAUTION

Do not connect accessories directly to the Nissan Armada battery terminals.
