MB brand Battery Question I have Solar BA9 battery/system tester. It needs accurate b

I have Solar BA9 battery/system tester. It needs accurate battery Type and Rating input to perform the test.

My 2004 E320 has Mercedes Battery, 2-years old, sticker info only shows: A 005 541 10 01, 12 V 95 Ah 850 A (EN), VRLA-BATTERY.

It is my understanding VRLA (valve-regulated lead-acid) could be either Gel Cell or AGM (Absorbed Glass Mat) or even wet cell acid.

I went to a dealer hoping to get some answers… I left with zero confidence I got any…

Asked the Parts person, he said it's a gel cell. I said are you sure it is not AGM? What's AGM he asked… oops… he was looking at his computer screen and said: fiberglass. I said that sounds like AGM… he replied… I don't know, why don't you ask service people. I did… they said: its a standard (sealed) wet acid battery. I'm pretty sure it isn't but…

Does anybody know… for sure… what kind of battery this is?

See if this is of any help.

Battery Types: Flooded versus AGM and Gel

2004 left factory with flooded batteries and sounds like you had it replaced with the same type.
What are you trying to test?
Coming to what dealers know - years ago I notified California dealer that the cars they sell do have build-in governor.
They had no clue and even after checking they could not answer any questions.

What I'm trying to test is health and state of charge of my battery.

I had no idea how old the battery was until yesterday… I discovered production date sticker is hidden directly underneath main P/N sticker. Strange.

Also because of my (mainly short distance) driving I want to know if need to charge the battery periodically.

Test results are very different based on type of battery entered in the tester. When I tested it as standard flooded it shows 100% healthy, 100% charged and 940 A. This battery is rated at 850 A (EN). That's what raised my suspicion…

I know technology brings new gadgets every day and I have seen those cigarette pack-sized computerized tester, but I am skeptic.
I deal with batteries a lot. Right now have 7 batteries in my vehicles and this week will bring some more machinery with 5 more batteries.
The truth there is no way to tell the battery health.
When it comes to charging, all my MB fire the engine in less than 2 seconds and per my observation they get full recharge even on 1/4 mile drive.

I like gadgets… especially those that actually work.

I deal with batteries too. Car, Camera… My cameras have battery analyzers. Are they 100% accurate? I don't know but, observing the patterns of behavior over the years… very useful tool to determine when I need a new one.

Why should I be skeptical with car battery being tested by something smaller than a brick?

How do you know your battery is fully charged after 1/4 mile drive?

Battery is all about chemical reactions, while electricity is the result. The tester you have is measuring electricity, meaning you are trying to test condition of chemical reactor by measuring the side results.
To some extend I would compare it to judging car corrosion by looking at shiny paint only.
Fully charged battery will be close to 13V after disconnecting the charger and after few hr it will drop to about 12.7-8V.
If you see that on car display, you know you have healthy system.
The only good way to test flooded battery is with one of those below, but who wants to get his fingers dirty in era of electronic gizmos.

Personally, I would be more concerned about the health of the voltage regulator on the back of the alternator. Assuming your battery terminals are squeaky clean your battery should last for at least the length of the quoted warranty time. My '97 CL600 had only 2 owners. The battery looked ORIGINAL. I contacted the dealer and they said the battery was replaced about 10 years ago! The second owner was cheap and I have to assume that if he replaced the battery it would not have been the $360 Bosch battery that was in the car. So, did I have a 10 year old battery? My guess is yes. We used a hydrometer to test each cell and found a weak one. Remember hydrometers? Because there was one weak cell, I went to Interstate and bought a 7 year battery and paid about $200. I'm good for another 7-10 years.

I have $90 Bosch battery in our Bluetec.
PepBoys had a sale about 3 years ago, but even now the batteries sell for about $120 with 90 months warranty.
