May I suggest replacing your OEM battery with an Odyssey PC 1400/35. $260.00 This is an exact replacement... I use a lighter/smaller Odyssey PC 925.
These are dry cell batteries that can never leak... they can even be mounted on their side or upside down!
If kept on a float charger when the car is not in use batteries like this can last ten years.
Been using these batteries for years in both street and race cars.
