Very difficult to review a battery, but for me I had to consider both a quality company to buy from and a quality named item to buy. I needed a new battery for my car remote and this fits the bill - it works well and I know from past experience there are companies out there willing and happy to rip you off by selling rubbish inferior batteries, so I'd simply say to buyers - to be sure of quality buy a quality battery from a well known company such as Amazon as their supply chain will never last long selling them junk.
