Some vehicles like this Mercedes-Benz E320 have two batteries. They have the regular 12 volt starting battery and an auxiliary or a small additional battery that is usually used to keep the vehicle's electrical system voltage from dropping too low during periods like start/stop when the engine starts. This is particularly useful to keep thinks like GPS's and computers from resetting. This Mercedes has it's little auxiliary battery located under the hood, under a little cowling. The main 12 volt starting battery is back in the trunk. To replace this small auxiliary battery, which will go bad after awhile, is a fairly straightforward procedure. Although this video may provide you with the basic procedures, we recommend that you check with the vehicle manufacture's step by step procedures found in service/repair manuals for the vehicle you are working on.
Even if your vehicle did not come with an AGM battery, you can upgrade to an AGM battery for up to 2x the life. AGM can be found at most retail outlets. You can learn more about AGM here: www.autobatteries.com/battery...
The use of a memory saving procedure will keep the memory alive on the vehicle's computer during the battery replacement procedure. Referring to our Memory Saving video will provide you with various memory saving procedures that can be used according to vehicle manufacturer's requirements. • Vehicle Memory Saving ...
Some late model vehicles must have the 12 volt battery registered with the vehicle's Battery Control Module or Computer after replacement. See these videos on Battery registration and coding for more details on the procedures at • Battery Registration w... & • Battery Registration &...
Always wear safety glasses and gloves when working with or near batteries.

Nice simple video that doesn't over-complicate this. Confidence in this guy who is ASE certified and does it right. A different video shows a guy taking the red terminal off first and reconnecting it last. Wrong. Again, nice job on this one.

Hi - Thanks for watching! According to BCI, the auxiliary battery is a Group 400 AGM battery. We recommend that you refer to the vehicle owner's manual or a service/repair manual for the proper charging procedure for your vehicle to be sure.

Could the aux battery cause the car to not start? or the main battery? I have a 2005 e320 but my ignition switch would turn because it won’t read the key. Could the battery be the problem, EIS, or a new key?? By the way everything internally still works. Radio, lock buttons.

Hi - Thanks for watching! Usually, vehicles like yours use the main battery to power things up and start the engine, but we suggest that you check with a service/repair manual for the vehicle (available at the dealership and auto parts stores) for the best diagnostic information.

On my 2014 GLK350, I used A BATTERY TENDER device to maintain power to the system while the rear computer battery was changed. On the Battery Tender, hook the black negative wire to a ground under the hood (look for BROWN wires laned under a screw or bolt. Look for the jumper terminal under a RED cover - slide open the cover and attach the RED Battery Tender wire to the jumper terminal. Now change the rear computer battery as shown in this video.

What is the auxiliary battery used for and when do you know when it needs to be replaced? Wouldn’t the main battery be good enough for the electrical systems as well? Either ways you will connect a back up battery (in parallel) before you change the main battery but is the same (parallel connection needed) to change the auxiliary battery as well?

@worldpeace5853 4 жыл бұрын

The Battery Shop How do we know it’s time to change the auxiliary battery? Should we do it at the same time we change the main battery? That means change the auxiliary first, hook up an external parallel battery and then change the main battery?

The boss of the workshop says the dash will indicate aux battery fault only when it is deplete. 🤔😁😁. Any comment?. Anyhow had ordered one new aux battery to replace it. Regards.

Hi - Thanks for watching! We suggest that you check with a service/repair manual for the vehicle to see when the AUX battery is considered too low to be useful and trigger a fault. Typically, a 12-volt battery at or below 10.5 volts (10%) is considered to be discharged.
