Unless you put in 1 that's below the recommended, you won't have to worry. Stick with the proper EFB or AGM (Q85 upwards).

In addition to sir travs recommendation, best to have your battery replaced at your convenient time. Much better than dealing with a dead battery while you're on the road.

Dealership. What's your fin's PN? I know Mazda uses at least 2 different antenna nut types. The stock from the M2 stick aerial won't fit the sharkfin, while that from the 1.5 BM does.

Nut from stock antenna of 1.5 BM doesn't fit the oem sharks fin. No available nut from dealership. No luck from hardware. Even in Banawe. Had to look in Amazon.
