Renault Megane - Video tutorial

Model: Renault Megane Megane 1 - Years 1995-2003
Part: Battery
Operation: Check battery efficiency and charging system

Once the position of the battery has been identified, which in the case of the car in question is on the passenger side, immediately under the windscreen, check that the terminals are well tightened and do not show any formation of oxide or corrosion; also check that the battery does not have any acid leaks. The first measurement of the state of charge of the battery must be made with the engine off and the ignition on (the battery warning light must go off); place the multimeter on the 20V direct current scale, and connect the test leads to the battery poles respecting the polarity: an efficient battery must give a voltage value between 12. 3v and 13. 5V. Check the voltage drop during the starting phase to test the starting of the battery: it must not drop below 8V. Then proceed to check the charging system making sure that the auxiliary belt that drives the alternator pulley is intact and does not show cracks; then start the engine, make sure that the battery warning light goes off and measure the voltage at the battery poles: it must have a value between 13. 2 and 14. 8 V. Finally, to check the stability of the alternator regulator, activate all electrical drives (headlights, indicators, defroster, passenger compartment fan) and check that the voltage does not drop below 13. 2 V (it may be necessary to accelerate a little).

How do I replace the Land Rover Evoque auxiliary battery?

In order to replace the auxiliary battery of the Land Rover Evoque, it is necessary to go inside the passenger compartment and remove the panel which is positioned immediately under the glovebox. Once the screws that secure this panel have been loosened, it will be possible to access the components located in its rear part, including the auxiliary battery. The latter must be disconnected from its cables and the fixing screws must be loosened. The battery can then be replaced with a new one and the panel can be fixed again with its screws.
