Battery Bosch or OEM BMW

Also the original equipment Bosch battery that came in my wife's 2006 TDI Golf when we bought it in 2015. The good ones aren't available anymore by the time they wear out.

For about a month I have owned a 2016 REx whose 60 Ah battery is supposed to get 72 miles. This week I fully charged it and have been commuting four four days without topping up. Today the REx kicked in with the trip meter at 73.3 miles. This was a mixture of city traffic jams and short bursts on the carriageway, mostly with the air con on and mostly in Comfort mode. So I'm pretty pleased.

My truck has a 4 or 5 year old Bosch in it, still works great.

Factory exhaust manifold cooling and Bosch battery.

I purchased 2 as a drop in replacement for an old 1400VA APC UPS.

I couldn't find the datasheet on the bosch website but I found out via a few online posts that these batteries are actually manufactured by Exide.

FYI I went with the Bosch 96R. It weights about 34 lbs and fits no problem although I did need to add a small wedge on top of the bottom lip to lock it down with the stock mount. It has a 3 year free replacement warranty and cost me just about $87 OTD @ PepBoys after turning in my $15 core. It's been more than a year and the battery has been rock solid with very little use.

I am still on my original battery in my 2007 335i w/ 87k miles.

The last two batteries I bought for my GTi, were specified for a Mk4 Golf/Jetta. Both of them were Bosch and they are both different sizes. Both of them ran me about $150 I went with the Mk4 batteries because Pepboys didnt carry for a Mk3. But both of them are fine

Some BOSCH batteries used on VW cars last around 2 years or a bit more but cost appropriately.

I've been seeing the same issue with batteries branded under Bosch and Champion. On several cars, I rarely had to replace batteries, now it seems like it is a 1-2 year thing on any battery. They are dying faster without ability to recharge. I just posted in the Scirocco forums that my 3 year warrantied Bosch battery is no longer holding a charge and its not even 11 months since I bought it. Glad to know that I'm not alone in seeing that engineered battery obsolescence seems to have arrived.
