About one year ago, after terrible customer service from a major UPS vendor, I decided that I was now only ever purchasing backup batteries from CostCo: their "lifetime satisfaction warranty" means I don't have to deal with OEM return processes (IMHO) designed to prevent claims submissions (e.g. return shipping fees; questions designed to invalidate your warranty).
