Maxell CR2016 3V Lithium Coin Battery - 5 Pack for Watches, Calculators, Key Fobs & Small Electronics - Long-Lasting Power for Everyday Devices

Best price for replacement watch batteries for a couple watches. All these button batteries fit and perform basically the same no matter what manufacturer, as long as you use a good name brand like Maxell, Energizer, Duracell, Rayovac, Toshiba, Panasonic, Sony, or similar. Even if one brand or another can show its battery is longer lasting, it will not be by much, and you certainly will not ever notice a difference in these long lasting low usage situations like watches or car or garage remotes and the like.I would stick to a brand name you know and recognize simply because you know they make quality goods in general and would not risk losing your confidence by putting their brand name on crappy stuff just to make a quick buck. When a battery fails other than running out of power, it is because they leak chemicals which can corrode and destroy whatever electronic item you use them in. It is not really worth saving a couple pennies and putting your electronic gear at ris by being too cheap to buy a brand name battery. So for the most part buy brand name button batteries based on price, once you know the model number that fits your need. Stay clear of the generics and off brands IMHO. More likely than not those off brand batteries will work fine without a problem but you decide if risking your electronics is worth it in order to save a couple pennies per battery.Oh, also buy in bulk. These things store great for relatively long time.
