My experience with auxiliary battery replacement
Hi all, I'm new to MB but I wanted to share how I replaced the auxiliary battery in our 2011 E350 wagon.
I ordered a cheapy from Amazon. Size is perfect but the terminals are opposite of the MB battery. I also had to solder a larger terminal,which came with the new battery, on the replacement. I was able to get it done but it did make a fiddly job more fiddly.
This is the battery I ordered.
I assume this was the original aux. battery
Replacement in the car and you see the positive side is on the inner side instead of outside.

Good job , thanks for sharing
There's something I have noticed . Your OEM is 12V 1.2 Ah but replacement is 12V 1.3Ah but that should not cause any problem

chargeable battery....
Did you check the chaging voltage was present after replacement?
Sometimes the old short-circuited battery takes out the charging circuit.
Once you see better than 13.5VDC, it's all right.
Below 12.5V is discharging.
You can read that battery with your scanner or with DVM.
🤞

Painted GND Cleaning club...
It's free to join then pain-free driving afterwards.
Proceed while batteries are disconnected in the following order:
- Main chassis GND strap located under carriage
- Trunk GND Posts on both sides behind carpet
- Footwell GND Posts both sides
- Engine bay GND under both beams
We suggest you purchase a LAUNCH cReader Elite to help empower your troubleshootings. After initial graduation other planted opportunities await for your fixing: loose internal pins.

First, Taiwan is not China, the quality differs, second, the battery will take some time to charge in the car, especially if it was not charged prior to installation. Is the light still on? It should go away in a week of driving if it wasn't too discharged on installation.

Correct, it also depends on the typical drive time. As is obvious, the longer the normal drive time the less days to charge the unit. And, as the owner of a 2011 E350 who had the same issue. I played wtih BatteriesPlus units and just paid for an MB battery to just get everything working properly. Cost of ownership.

Hard to argue with something like that.
I on other hand, make over 100 orders on Amazon every single year. They have good deals on motor oils, ATF, pool chemicals and thanks to Prime membership, I can find "open box" expensive items for less than 50% of their original pricing.
Most of the orders come in 1 day and I have free, 30 days returns that I sometimes abuse.
When amazon has poor software for car parts matching, when you know what you are looking for, they are the best source for OE pilot bushings, common on 5G transmission for years.

Wrong
I believe in supporting small businesses and local retailers. So, they will be there when I need them. Also, Amazon does not sell anything, it sells something for somebody else.

I AM a small business. That said, I am not mad at my money.
As far as the business model of Amazon, you are free to spend your money in any place you would like. For me, it is more a matter of the value of my time. That said, recently a buddy of mine got a "great" deal on some bike parts on Amazon that were 100% China knock off items (this is the real ones - the Amazon ones looked 99% correct - did not work at all). The nice thing? Amazon took the return for a full refund...so...we have that. As for local shops? Well, if you can find good customer service for a household item I would also assume you are willing to pay more for grocieries at a locally owned gas station than a "Corperate" place like Kroger, Publix, Walmart and the sort of evil corporations who are eating up the small guys...where I am, the only "local shops" for household things in general are reselling things they picked up at a Publix Bogo or at Walmart.

Thanks to that I am receiving lot of items even on the same day (if I order in the morning) when 1 day delivery is very common.
I also bought from amazon vendors, with mixed results, but each time I had a problem with vendor, the amazon would step in and do it right.
As for smal, local business, on one hand I would like to support them, but on other hand, if they can't stay competitive without 400% markups, .....what can I do?

Careful with amazon, they used to have better prices than anywhere else but that was part of there plan. Regardless of prices they are generally not an authorized seller of many things, they wont tell you this but many items do not have the claimed manufacturer warranty when bought thru the big amazon. They also send out returns as new hoping the next person wont return it, oh and many manufacturers sell there seconds thru amazon for the full retail price. Something to be aware of.
I still use it occasionally but its not as often as it was several years ago. Primarily use it for vehicle filters and such but even that is a crap shoot. Gotta check those filters make sure they arent broken or not the OEM manufacturer filter which happens on occasion.

As for warranties, when you buy from a vendor, having his own website as well, you can follow the warranty via it. I do that with my pool chlorinators for years, who kill the probes prematurely.
I always check the warranty listed on amazon, who often ask for contacting the vendor directly.
One time I had vendor who refused to pay return shipping for electric scooter. I contacted amazon and they refunded me $90 shipping cost from their account.
Than each amazon purchase gives me over a month of hassle-free return, even on items not having warranty.
