⚠️ Attention: Before starting work, make sure that you are not near flammable materials. Even a spark when removing terminals can be dangerous in a confined space.
Battery location and access features
On most modifications Nissan Juke The battery is located in a standard location under the hood, but access to it can be difficult due to plastic decorative trims. In some versions, especially with turbocharged engines, the space under the hood is filled with additional equipment, which requires careful disassembly.
Sometimes the plastic air duct or protective cover must be removed to access the top of the battery. This is done manually or using a screwdriver, depending on the type of fasteners. Do not use excessive force as the plastic clips are quite fragile and may break.
Pay attention to the location of the positive and negative terminals. On Nissan Juke they are often covered with plastic covers that must first be removed. This prevents accidental shorting to the vehicle body while performing work.
- 📍 Check for plastic plugs on the terminals
- 🛠️ Free up space from unnecessary parts (air ducts, casings)
- 🔍 Inspect the battery mounts for corrosion
If you are faced with a situation where access to the battery is completely blocked, you may need to remove the entire battery cage. This is a more complex procedure that requires unscrewing additional bolts securing it to the body.

- 1.5 dCi (Diesel)
- 1.6 (Gasoline)
- 2.0 (Petrol)
Procedure for disconnecting terminals and removing clamps
The key rule when working with a battery is to always remove the negative terminal first and put it on last. This rule also applies to Nissan Juke, as it prevents a short circuit if the wrench accidentally touches the car body when unscrewing the positive terminal.
First, unscrew the nut on the negative terminal with a 10 mm wrench. Remove the terminal from the terminal and move it to the side, securing it so that it cannot accidentally return to the contact. After this, proceed to the positive terminal, having first removed the protective cap.
After disconnecting the electrical contacts, it is necessary to loosen the battery itself. Usually a special clamp is used at the bottom of the battery, which presses the battery to the pad. Loosen the nut on this clamp and carefully remove it.
☑️ Instructions for disabling
Sometimes the terminals stick to the terminals due to oxidation. In this case, you should not hit them with a hammer. It is better to use a special puller or gently wiggle the terminal, having previously treated the connection area with an oxide remover.
If the vehicle is equipped with Start-Stop systems, the process may be different, since batteries with AGM or EFB technology are used. In such cases, more careful handling of current sensors is required.
⚠️ Attention: Never use metal objects to pry the terminals, as this may damage the lead terminals of the battery, causing it to fail.
Removing the battery and preparing for replacement
Once all the fasteners are loosened and the terminals are disconnected, you can begin to remove the battery. Lift the battery strictly vertically, avoiding tilts, so as not to spill the electrolyte in case of leakage or damage to the case.
Carefully inspect the area where the battery was located. Dirt, water or oxidation products often accumulate there. Before installing a new battery, this area must be thoroughly cleaned and, if necessary, treated with an anti-corrosion compound or terminal lubricant.
Check the condition of the battery you are removing. If it has cracks or signs of swelling, dispose of it at a specialized collection point. Do not leave an old battery in the trunk or garage as this can be dangerous.
- 🧹 Clean the site from dirt and oxides
- 🔍 Inspect the old battery case for damage
- ♻️ Prepare a place for disposal of the old battery
Be careful when removing the battery as it may be heavy. Use proper lifting technique to avoid injuring your back. If the battery is too heavy for one person, ask for help.
What to do if the battery is stuck?
If the battery is too tight, do not use metal levers to avoid damaging the side members. Try gently rocking it from side to side, or use wooden blocks to create leverage.
Installing a new battery and connecting
Installation of a new battery begins by placing it on a cleared area. Make sure the battery is level and not wobbling. After this, install the lower clamp and tighten it until it stops, but do not overtighten, so as not to damage the battery case.
The next step is connecting the terminals. The positive terminal is connected first, and then the negative terminal. This is the reverse sequence compared to shutting down. Tighten the nuts securely to ensure good electrical contact.
After connecting the terminals, it is recommended to apply special grease or technical petroleum jelly to them. This will prevent the appearance of oxides in the future and ensure stable contact in all weather conditions.
Check that all protective caps are in place and do not interfere with the movement of other parts under the hood. Make sure the battery is securely fixed and does not move due to engine vibration.
Before tightening the terminals, make sure that the terminal seats are clean and free of corrosion. This will ensure better contact and extend battery life.
Resetting errors and setting up electronics
After installing a new battery on Nissan Juke It may be necessary to reset errors that occurred in the energy management system. Sometimes the on-board computer remembers the parameters of the old battery and may not work correctly with the new one.
