If it's the original battery, I'm surprised it lasted this long. Batteries today, and more specifically the cars and all the electronics that drain them, even when not running usually require replacement more frequently, 3-5 years at the most. My 2011 E550 has been though 2. So I'd verify how old it is,,probably just needs replacing. I concur with buying the tender especially if it's not going to be driven regularly. I have one for those rare times it will sit for more than 6 days. I haven't had to get a battery for this car yet but I would think most auto part stores could provide one without paying stealer ship prices.

 

Would watch out on jumping as per usual. Can blow airbag system so I'm told which is v expensive to sort.

Should I be worried about the idea of jumping this? Does it jump like any normal car? Or are there additional risks.

 

The service tech at the Maserati dealership here in SEA told me last weekend to expect as little as one year on a battery without a tender, and around 3-5 years with the tender.

 

Its just like any other car. However, jump starting any modern car can get slightly risky with all the electronics on them...You can get surges that can cause damage occasionally, but its not real common...Best to leave your donor car hooked up for a bit and let it charge your dead battery...Most people hook them up and wait like 10 seconds and try to start the dead car...Let it run like 3 minutes or so....Jason

 

Appreciate the advice!

I have another good question, any concern about buying a battery from my local Orielly's or Autozone? After giving them my make/model of course and avoiding the cheapest one. Would this be ok?


edit: I just called my local oRielly's and they have 3 makes in stock, one for $139, another for $149, and another for $169 that's made a bit different and "lasts longer" - 2 year warranty on the first and 3 year on the following two.

 

when you jump it, make sure to reach all the way to the positive terminal. if you clamp on the inboard side of the positive junction, fuses will blow. the expensive kind too.

 

Clamp the positive side first, then the negative. Then buy a C-Tek battery tender.

 

^ I skipped jumping and bought a battery charger.

Hooked it up to the actual knobs on the battery, not the circuit looking things above.


Back to the earlier question, does anybody recommend a certain battery for the GT? Does it have to be a certain brand/anything like that?

 

Interstate H8 is probably your best bet...Go to Interstate website and see if there is a dealer near you....Jason

 

My OEM battery (with a tender) lasted just over two years. I installed an Interstate and it has been fine. Slightly different shape, but bolts down very securely.

 

We've heard of many problems jump starting the Maserati, we wouldn't recommend it. It seems that there isn't great protection on the electronics from the surge. Maserati also does not recommend this from what we've been told.

Use a trickle charger on the battery, get it to full charge and go from there. Sounds like you've already done this but just wanted to offer this advice.

As to the battery, many people seem to go with Optima Red Top batteries. I can't say that they are the best but they are commonly used on the Maserati and seem to be OK. Agreed that a Interstate AGM would be a good option but sounds like it may no longer be available.

Best Regards,

 

I just picked up an an Interstate MT5-49/H8 AGM and installed it myself last night. 15 minute job, works like a charm and fits perfectly.

 

Thanks everybody


A quick google search of that Interstate battery came up with this

Battery-Mtp INTERSTATE MTP-49/H8

That looks like the ones you're all talking about. Tempted to buy one soon, shipping is free

Edit: Just kidding, looks like that's not the AGM version and it says MTP, not MT-5. I'm no battery expert but doesn't look like quite the right battery.


Edit 2: Looks like they still have some of the AGM batteries for sale online, see my next link. The price is pretty high though, maybe the price is high because it's discontinued? Can anyone confirm that's the price you should pay?

This link is $251 + $40 in shipping.

Your second link is the correct battery.

I went to the Interstate Battery Center to pick mine up here in SoCal and the guys said that it is NOT discontinued, so I'm not sure where that info is coming from.

AGM is their maintenance free high capacitance battery. It is definitely the only one I'd put in the GT, which is already notoriously hard on batteries.

 

Could someone advice me what is the equivalent battery from Bosch?

There is no Interstate brand name in my country.

Thanks in advance.

 

I've talked to a few different people and apparently as long as it's the right size and has the same cold crank amps, it should work.

The size group is 49 (although every battery company I've called has their computer telling them size group 48 works??) so 49, and just make sure the cold crank amp works.

A few places I've talked to say the AGM version Interstate has essentially means it's recharged easier, end result is the battery lasts longer. I'm going to buy one from NAPA Auto Parts, apparently they make good batteries.

 

Here's the Bosch Battery----- H8/L5/49 its a 900 CCA and 1050 CA battery, its a beast !!
just google it...

Bosch Premium Performance Battery Group Size H8/L5/49

That or the group 49 battery with 900 CCAmp from Interstate, I've had good luck with all their batteries

 

Just thought I'd update the thread, it didn't actually die quickly, I see it was about 2.5/3 years old.

I bought a battery size 49, and learned that size 48 won't really fit so if you guys have a 2009 like me (I'm sure they all use the same size) size 49 is the way to go.
