battery

FWIW: Consumer Reports tested many batteries and posted results in the November, 2010, issue. Everstart batteries (Walmart) tested better than Interstate in three of five battery groups. Also, the Everstart warranty (free-replacement period and the total prorated periods in months) is 36/108, as compared to Interstate's 30/85.

Am definitely not a Walmart fan but have to admit that the two batteries bought from them are still doing great and have already long outlived the Interstate batteries they replaced. The Houston Sams Club batteries are more expensive and a friend has used them both in his car and his boat. Local opinion is that it is impossible to get a warranty on a faulty Interstate battery. These batteries are not Chinese. Cannot comment if they are any better than the Costco batteries.

If you want a much better battery than the Optima use the Deka 9AGM48 battery. It's the same technology as the Optima but with better CCA, AH and price than a comparable optima. Reviews have stated that the Deka 9AGM48/49 batteries make the Optima look like hearing aid batteries. It's also not a spiral wound battery like the Optima which has a lot of wasted space in it's design.
The AGM technology is known as Absorbed Glass Mat, Fleece, Valve Regulated, completely sealed battery. You an actually operate the battery upside down.
No, I'm not a salesman for Deka. I'm just responding to your comment about wanting a sealed battery that does not vent acid fumes. I bought the Deka battery for the long life, extra performance and the fact that it is sealed. I just went through all this crap in search of a battery for my ML. If I had found East Penn / Deka 2 months ago I would have also bought that for my 190E.

Battery Sizes.

Most Mercedes, and other European vehicles, use one of two battery sizes.
Group 49, Din size H8, En size 88L5
and
Group 48, Din size H6, En size 66L3

The Group 49 is used in the bigger vehicles like the ML's.
The Group 48 is used in the smaller sedans like our 190E's. (still a big battery)

I just replaced both my 190E and ML's battery in the last 2 months. It took me a lot of searching to figure out what battery sizes I needed. The Group 48 and 49 are European vehicle sizes. There is still a variety of specifications like CCA an AH ratings within each group. I bought a Group 48 battery from AutoZone for the 190E and a Group 49 9AGM49 AGM battery directly from the manufacturer, East Penn / Deka, for the ML.
Deka also has a 9AGM48 AGM battery if you want to spend a little extra money for the new battery technology.

+1 on this.

I buy blems directly from Deka at their retail store/outlet; as I live about 5 miles from the plant. A group 48 "blem" for the 190E runs about 50 bucks and carries a 5yr warranty. A blem might have a scratch on the case, or have been pulled from the line for testing. It carries the same warranty.

My 330i has a Deka ExactFit 49 AGM, it wasn't cheap, and it's a monster... something like 1090 CCA with a ridiculous reserve capacity in amphours. It is completely sealed.

Deka makes batteries for many retailers.

That's all they had at the time.
The sealed AGM batteries were a development project between Hoppecke and Mercedes in Europe. The result was the Hoppecke VLIES.Tec battery. Hoppecke was bought out by Johnson Controls and is now known as a VARTA battery. The new AGM sealed batteries are used in just about all Mercedes vehicles an is the Mercedes 005-541-10-01 Fleece Technology battery. You can buy this now from Mercedes for your ML and is considered a replacement battery for the original lead acid batteries. Of course you are going to be paying much more for the Mercedes battery than the equivalent Deka battery.

Note: Fleece Technology is another term for AGM and VRLA. These batteries are completely sealed therefore they do not need any vent tube. I think I mentioned before that they can even be used upside down.

Optimas are made in Mexico now. Not like the original ones which were made in USA- that all the raves are based on.
I have been using the yellow tops in comp sound cars for a long time with great results. I have bumped my system with the car off running 2 15 for hours and it started right up when i was done.
I have not looked into a Deka batery but I will only run seald batterys in any of my cars.

ferget square batteries they are old school. I got the Optima Red Top and since i had it for 2 years it has never failed even minus -20C it shows no sign of weakness. IT is also spillproof, vibration proof because it's not a square design its 6 cylinders grouped together. It's about 160$ or something at walmart or costco.

The size 49 doesnt have that high of CCA ratings. Deka chart says 700 @0 degrees F.
The Interstate MTP91 has 700CCA. The 9AGM48 has 760 CCA's so it is just a little bit more. It also says the AGM has a flush vented cover according to the manufacturer. Would you kindly take a closer pic of the top for us to see? I might switch over once my MPT91 wears out in 6 yrs.

Interstate MTP91 battery has a 85 month warranty. Deka one is 70 months.

According to the Deka Manufacturer's (East Penn) chart The Group 49, 9AGM49, battery has a 900CCA @ 0F not 700A. The CA is rated at 1035 Amps.

I looked at my battery and I can see no vent holes anywhere and the battery is completely sealed. I can't take a picture any better than the one above. Other literature, which I can't find now, states that the battery can be placed in any position, including upside down an still function normally. I have also seen the term completely sealed and flush non-vented cover.

If I'm wrong I would really like to know and please provide links to your references.\

Here is my reference:

Yeah Cypress is right too. I dont think they make a DIN size H6 which is what the 190E needs in a sealed form. The 49 for the BMW is sealed but not the size 48. I have checked out the Optima Red Tops and they are pricey. Arent the terminals like reversed too? I think the Yellow ones are so the Positive terminal is on the left side instead of the right side.

I have an Optima Red Top in my 190. They do make an "R" (reverse) version which switches the position of the terminals (neg is left and pos is right).

Now to find a Deka battery dealer closer. I cant believe there is only 1 dealer in the entire SF bay area. What other brands are there aside Optima and Deka that offered a sealed battery?
If you really want a Deka 48 AGM, let me know. I can stop by Deka and pick one up for you. I can ship it FedEx ground/freight. Plan on about 60lbs from 18062. If you dont mind a blem, they are half price, but they don't always have them in stock. It's hit or miss.

Odyssey also manufacture AGM batteries. Their ER15 is very popular with the E46 M3 crowd looking to save weight. Their PC1220 is a group 48 size. It's pricey at about $300.

I dont have an ax to grind either, however a random post above about Optima irritated me. There are FAR better batteries on the market.

Just bought a battery today from Interstate. The old one was about 5 to 6 yrs old and has went through some harsh winters and much sitting. I noticed 2 cells low on water, filled em, but the poor thing just wouldn't hold a charge for a week.

SO.
Off to interstate for another "blem" battery, like the last one.
Price? $30.00 + tax = $32.10, and if I had the car with me, they would do the swap.

I opted for 750cca, instead of the 550cca that the manual calls for. Why? I would rather burn up a starter over a long time (which is unlikely, since I've used 750cca's for the past 10 yrs), than not have enough juice and spin in January/February, when the temps regularly hit below -20deg, on cold mornings.

Anyways, be wise and don't dump $200 on a battery for "show", unless you have a "show car". This battery actually looks like new.

Are you sure your Interstate is a blem and not a rebuilt? My Interstate company down the street sells them for $60 bucks rebuilt. Not sure how good they are using old batteries and pouring acid in them. $30 bucks sounds like a steal if they are just a blem. I love my Interstate MTP 91 for my 190E. Also got it in the S class too. Only issue we have with them is the spraying acid out part. Real bad when your battery is in the trunk! My last one lasted 6.5 yrs and most of it spent outdoors in the Las Vegas heat and the Las Vegas cold. Drove the trip from San Fran to Las Vegas like 16 times. I lost track. Gotta have quiet tires for those long drives and a nice sound system or you will go insane. My best time was 6 hours and that was going 120mph most of the way. Back then there were no cops with budget issues. Now the trip takes min of 8-10 hrs with traffic and a lot of CHP and local sheriffs and local police patrolling freeways where it was only Highway Patrol traditionally.
