Planning a road trip to RAK – should I get my battery checked in Majan first?

I'm heading up to Ras Al Khaimah for a long weekend with the family and my car's been sitting in the garage in Majan for a couple weeks without much use. I don't want to end up stuck somewhere on Sheikh Mohammed Bin Zayed Road with a dead battery, especially with the kids in the back. I've heard about on-demand car battery service in Majan Dubai that can come to your home and test the battery before you leave, but I'm not sure how accurate those mobile testers are compared to a proper shop. Has anyone used a service like that for a pre-trip check, or should I just drive to a battery shop and have them test it manually? Also, if the battery is borderline, do they usually recommend replacement right away or can you squeeze a few more months out of it? Just trying to avoid any unnecessary spend but also not risk ruining the trip. Appreciate any thoughts.
