Default Interstate MTP 48-H6 battery correct?

Iím buying a 5 year old Karma tomorrow and one of the first things I plan to do is replace the 12volt battery. Iíve read numerous posts on battery replacement and it looks like many people are replacing with Interstate MPT 48-H6.
The original battery hasnít been replaced (Varta E39 AGM).
My research indicates the MTP 48-H6 is a wet cell with caps to add water(Summit Racing Specs).
The MTP 48/H6 is a maintenance free battery (same as the Varta E39).
Seeing the battery location appears to be hard to access and to add water, shouldnít the MTP 48/H6 be used?

I'm thinking about preemptively replacing my 12v battery. Just to confirm, is this the correct battery?

So is this still the best option. When I use the link they say there is not a store near me (Detroit) that stocks this.

I'll apologize gain for asking this question, but I've been very confused with trying to locate the right 12v battery. Mine died this weekend - luckily the car was in my garage.


The link I posted above is to the MTP-48/H6, which I believe people have had problems with. When I researched the MT5-48/H6, the Interstate website shows that it was replaced by the MTX-48/H6. When I call Firestone for batteries they have the MTP-48/H6, but also carry an MT7 (WTH??) series that is an AGM and ~ twice as expensive. NOTE: Typically if I call an auto parts store and ask if they carry batteries for a Fisker Karma, they are initially confused and then answer "no."


Yes, I am battery ignorant. Can someone help me weed through my confusion?

I'm hoping this is a good replacement battery. Any thoughts or suggestions?


Thanks - Ed

I’m changing out my battery now, and I’m taking a lot of photos along the way. All I’m missing is a T40 star bit. When I’m done, I’ll post a step-by-step for anyone that’s interested.

I changed my battery over a two years ago because it lost it's charge - i failed by not using trickle charger when i leave the for more then two weeks. Pictures may help, but for the most part it's pretty straight forward. Passenger front wheel has to come of and the wheel well cover. The compartment is very small & sits in front the of the passenger compartment - the battery is very heavy too. On a lift it would be easier on the arms due to the position while parked. There is enough cable slack to pull it out to get the leads off and then it pure arm strength. putting a wood box near by at the height of the cavity would help, but i did it brutt strength sitting toward the cavity with my feet under the car. It not a fun experience, but doable for the average DIY.
