I drove my motorhome from California to Maryland last week. Before I left I bought a super starter battery. I needed 2 but the store only had one. I forgot to get another battery on my phone way to Maryland. Now I’m over 100 miles away from an O’Reilly’s. Can I get a battery from another manufacture that’s the same size And output and use them for coach batterys? Or do I need to buy 2 more battery’s ?
