I don't pick my GranTurismo up until March, but I've already made it clear to the dealer that the OEM battery will be replaced with another before i get behind the wheel. They said "We can do that... its no problem" and will use the Interstate as well.

Replaced with an Optima RedTop 34R at about 15K miles.
Then just replaced again with same at 37K miles.
Must have "killed" (discharged too much) the first Optima when left car without running for 3-4 weeks. After that, it did not keep charge for more than 3-4 days.

I have now bought a battery "tender" from Ctek (model MUS 4.3 + comfort indicator eyelet) - Jeff at Formula Dynamics mentioned the battery tender to me.
So I will be connecting the Ctek if I don't run the car.

The dealer replaced my battery with an OEM under warranty. After 13K??? I've been reading that the OE brand isn't as good as aftermarket. But which aftermarket to go with? Since then I've put it under a trickle charger while stored.

I had the OEM battery replaced in my '09 GTS in December 2013 with Interstate by dealer. OEM battery lasted 5 years. Dealer service person thought original battery was still good for at least another year. I said, let's not risk it. I ordered car new (arrived '08 December), and I have about 18K miles on it. I live in central Illinois, so I can't drive year round. When I don't use it I have it on a battery tender from Groit. One reason why OEM battery might not last is that car sits on a dealer lot for a period of time before it is sold. When dealer recharges battery, probably does a "fast" charge, which doesn't help with battery life. If one buys a new car, and it hasn't sat for a long period of time, and it is used fairly often, OEM battery is usually good, like my experience.

Mine was replaced with the OEM Fiamm. I went nuts when I heard the price and considered non-oem, but was concerned that it might void warranty if I had major electrical problems. (The car was still under warranty, and I have had a number of electrical problems.) After it was replaced at my cost ($750!), the dealer discovered what had been discharging the original battery, resulting in its demise. It was the power supply for the built-in radar/laser detector, which had been installed by the dealer when I purchased. This was the recommended wiring due to the Bluetooth communications between the main module and the sensors. Given that there is clearly no need for the sensors to communicate when the vehicle is off and parked, the tech re-wired the system so it was not always hot. End of problem. I was $750 lighter and very frustrated after having had a dead battery probably 6 times. Once it was replaced and a maintainer installed (I drive it infrequently), no problem.

I would complain to MNA and try to get your $750 back. The battery should have been covered under warranty. Which dealer ripped you off like that?

Interesting alternative battery/weight reduction proposition

I had this online chat with Braille a while back, just out of curiosity. Might interest anyone contemplating both a battery change and the opportunity to shed a fair amount of sprung weight:
BRAILLE LIGHTWEIGHT BATTERIES CHAT LOG
Mike: Hi Gary, what would you suggest as the correct battery to install in a 2013 Maserati GranTurismo Sport (4.7L V8)? BTW, I'm located in the UK so winter cold starting is a consideration. We don't go below -5 or -10 though.
Gary Savage: Are you looking for a lithium upgrade? I will look up the OE battery size.
Mike: I'm considering weight saving options, and thought one of your batteries might be an interesting & straightforward way to lose a few pounds? Any idea what weight reduction I could get?
Gary Savage: It is a very quick & easy way to save weight. The electrical benefits of lithium are almost more significant, in that they deliver a higher, cleaner voltage, which means quicker starting, improved engine management performance, less horsepower draw from the alternator due to efficient charging, will last 3+ times longer than lead batteries, all on top of a weight savings of roughly 40 pounds / 18 kg. Is this a daily driver or just occasional driver? Do you use a battery charger when/if the vehicle sits for extended periods of time?
Mike: It would likely be a daily driver, and so would probably get regular use.
Gary Savage: Even better. The nice thing about lithium is that it is not affected by cold as much as lead. The battery self-warms, so it will get stronger and stronger each time you start the car. You can even turn on the lights for a minute or so to warm it up and will deliver full cranking power.
Gary Savage: The I49CS would be the direct replacement for the stock battery and would deliver slightly more capacity. Our lighter weight I49CE/CS still has more cranking power than stock, but less capacity. You would have to use the charger on it if the car is ever going to sit for more than a week or two without use.
Mike: How much do these two weigh? The bigger is the I (i?) 49CS? Is the difference enough to be significant for the need for greater battery management?
Gary Savage: That is correct. Bigger in power and capacity, but all are the same Group Size battery. The CE is a low profile version of the CX model, both lightweight. Relatively speaking, as they are both 45-50 pounds lighter than stock. :) You are looking at a difference of 6.5 pounds / 3kg between the two versions. The heavier one has 50% more capacity and cranking power, but also costs a bit more. It never hurts to have "more in reserve", just depends if you want to give up the extra power & capacity for less weight.
Mike: Ok, thanks for the advice. But CX or CS? kind regards, Mike
Gary Savage: The CX is also a lightweight, just in stock height. The CS is the most power & capacity in full size battery. The I49CS is the model used in some of the Ferrari 458 Le Mans cars, as well.

While i agree its very pricey...I can see how it might make sense for anyone who can afford it, to aquire this technology for there Maserati. After all..if you've already spent what most people would consider a very considerable sum for an exotic Italian automobile...what's a few thousand more for a battery that will probably outlast the life of the car.

For me...i'll make due with the replacement Interstate.
