So here's something I didn't expect to deal with - my auxiliary battery just gave up on me and now my fridge and second battery setup are completely useless, which is a real pain because I'm planning a camping trip to Liwa next month and need everything working properly. I've got a Pajero with a dual battery system that runs my fridge, lights, and a few other accessories when I'm out in the desert, but the secondary battery has been struggling for a while and finally died this morning. I'm looking for a place that does certified auxiliary car battery replacement in Musaffah because I want someone who actually knows what they're doing with dual battery systems, not just a regular garage that'll slap in a random battery and call it a day. The main battery is still fine but the auxiliary one is the problem - it's a deep cycle battery that needs to handle being discharged and recharged regularly without dying prematurely. I've heard some horror stories about people getting the wrong type of battery installed and then having all sorts of electrical issues, so I really want to make sure I go to a place that understands the difference between a starting battery and a deep cycle one. Has anyone had their auxiliary battery replaced recently around Musaffah and can recommend a shop that actually knows their stuff? Also curious what brand you went with and how much it set you back. Appreciate any help.
