Just bought my 00 a few months ago, it has the original battery too but i started to get weird warnings saying my taillights were out and none of my rear bulbs were out.. kinda crazy replaced the battery after i read a few threads here and now no more problems... Just went to o'reillys and matched a optima red top stats to my oem then matched sizes that would fit in the compartment since they dont actually list one for my car. Always ran red/yellow tops and interstate batteries in everything ive ever owned. Havent had any issues yet with the red top in the bimmer

I have a 2002 325xit with the original battery in it. No problems, but have been considering changing it at some point. Just can't justify it until something happens.

I purchased a BMW batt 3years ago and it went out this month. Turns out they only have a 2year warranty another one would have run me $200 but given the life I got out of it, I decided to try the DL. It costs $175 but you get $15 for your old battery and I had a $40 autozone membership credit so I only paid $120. Plus they come with a 5 year full warranty.

Why not replace that. Your battery is over a decade old. It's going to die soon and leave you stranded.

Best Option To Replace OEM Battery

I'm using a Bosch battery for about 9 months or so, so far no problems. I had a napa battery before that which lasted about 7-8 years. Both are made by the same company that make the Bmw battery I believe.

A number of posts in this thread -- and others on batteries -- is that Company XYZ makes the batteries for Brand A, Brand B, and Brand C.

While this may be true, but it doesn't mean that the products are the same. With few exceptions, manufacturers will not sell their flagship product under a house label for less money.

For batteries, cases may look the same outside, but inferior material or weaker construction may be used. A less durable mounting method or fewer number of plates may be used. Or quality standards or tolerances may not be as stringent.

On rare occasion, the contracted house brand is "better". For example, Sears' appliances offer more features for less money than the Whirlpool, Samsung, LG counterparts from which they are derived. It depends on what the private label pays for and its negotiating power.

In the automotive world, the same company makes both the GT-R and the Cube. If you prefer German examples, then Lamborghini Aventador and VW Golf. Or BMW-specific: Rolls-Royce and Mini. Components are different. Specifications are different. Quality standards are different. Yes, for a long time, the Camry and Lexus ES were very similar, but there were meaningful differences that a discerning buyer could discern. If you wanted the properties of the Lexus, there was reason to buy it.

BTW, Consumer Reports recently had an article on automotive batteries (although our size was not covered).

The preferred non-OEM battery is the Bosch 49-850B. The Duralast 49-DL, is now out of production.

I've been considering. It just hasn't given me any reason to. I can't see any reason to replace something that works perfectly fine. I have jumper cables and AAA if it comes to that. I feel as if it will give some warning signs at least.

With mild Bay Area weather (no heat to kill it and no cold to stress it), the battery could last some time yet, and assuming decent maintenance and properly operating charging system.

When the battery in the '99 failed last fall, it was quick: it needed 2 jump starts in a week. But, there were no complaints about a battery that served for 13 years...in lake effect snow country, at that.

I am going to see how long I can push it. Looks like you certainly did well with yours. It's also kept in a garage. Never really any stress on it heat wise.

I've never seen a battery give warning signs. Usually they just fail to start that one time and you have to get a new one.

My BMW OEM battery lasted 5 years to the week before it started acting up.
I was jump starting the 330i on mornings it wouldn't start, then it was fine as
long as I drove it every day. If the car sat more than a day or two, I'd have to
jump start again.

So yes, batteries can show signs of their death. This one dropped 1 or 2 cells,
just enough so the battery wouldn't hold a charge above 12.2v (50% charge).

I replaced it today with a Walmart Everstart Maxx H7 (production date of 5/13) $124.99.
Fit like a glove without removing little white block. I looked for a 49DL battery first, but no
Autozone in my area had one newer than 9 months old.

Group 49 = DIN H8
Group 94R = DIN H7

The 49s have indeed disappeared from Walmart and Autozone, but the same batteries are still available albeit in European designation.

In over 25yrs owning BMW's I've bought 2 OEM batteries when the originals needed replacement. Why buy anything else? If they cost a little more, you'll forget about it a few weeks later.
