9 Confirming Electrolyte Level

WARNING: This page is about a different car, the 2018 Jaguar XE and 2017 Jaguar XE. However, it is still accessible from the selected car via links, so may be relevant.

WARNING:

BEFORE CHECKING THE ELECTROLYTE LEVEL AND TOPPING-UP THE BATTERY WITH DISTILLED WATER, REFER TO THE HEALTH AND SAFETY PRECAUTIONS SECTION.
AGM TECHNOLOGY BATTERIES ARE FULLY SEALED FOR LIFE AND NO ATTEMPT SHOULD BE MADE TO CHECK OR TOP UP THE ELECTROLYTE LEVEL.

NOTE:

In hot climates more frequent checks of the battery electrolyte level and condition are required. If necessary, the battery cells can be topped up using distilled water.
Only flooded batteries can have the electrolyte level topped up.

On certain flooded battery types the electrolyte level will need to be checked.

Make sure the battery is of a type suitable for topping up. These types of batteries will have cell plugs visible on the top face of the battery or a removable access panel to allow access to the cells.
On batteries with a clear or opaque case and level marks, check the electrolyte level by visual inspection of the maximum level indicator mark on the battery casing, indicating adequate level above the battery separators.
On batteries with black cases, remove the cell plugs or access panel and ensure the electrolyte level is level with the indicator in the cell hole. A flashlight may be required to see the electrolyte level on this type of battery.
If the electrolyte level is low, top-up using distilled water only .
Refit the battery cell plugs.
Charge the battery for 1 hour using a recommended charger, if a GRX-3080 is used select manual charging for an hour.
Carry out a battery test using the recommended test equipment in line with 4.6 Battery Test & 5 Equipment .
NOTE: Maintenance free and Valve Regulated (AGM) batteries are sealed and therefore cannot be topped up.

CAUTION: DO NOT overfill.
