So my 4x4's been sitting for a couple of weeks while I was traveling, and when I got back, the battery was completely dead – wouldn't even take a charge from my trickle charger. I've been looking at Optima batteries because I've heard their AGM spiral cell design is brilliant for off-road use and handles vibration much better than standard batteries, which is exactly what I need for my weekend desert drives. I'm based over in Industrial Area 3 in Sharjah, and I'm trying to figure out who supplies Optima car batteries in Industrial Area 3 or nearby, because I'd rather pick one up locally than order online and wait days for delivery. I found a couple of places online that might be relevant – there's a battery wholesaler called Al Nisba Trading LLC located right in Industrial Area 3 on Al Mulla - 2, though I'm not sure if they specifically stock Optima or just do general batteries . I also saw a listing for AES Trading LLC based in Sharjah Media City that offers Optima batteries, but I think that's more of an office/warehouse setup rather than a retail shop where you can just walk in and buy one . There's also a mention of an Optima battery shop in Industrial Area 4 near Clock Tower, but that's a bit of a trek if I don't know exactly where I'm going . Has anyone recently bought an Optima battery from a shop in Industrial Area 3 and can point me to a reliable place? I'm hoping to find somewhere that actually has stock rather than having to order it in, and ideally somewhere that can test my alternator and fit it properly as well. If the local shops don't carry Optima, I might have to consider a mobile fitting service that covers Sharjah – I've seen some that deliver and install batteries right at your location, which would save me driving around with a dead battery . Any recommendations would be really helpful, because I need to get the 4x4 back on the road for the weekend trips.
