Snark tuners do not all take the same battery size: it depends on the model. The Snark SIL-RED takes 1 CR2 battery, while the Snark ST-8HPT is rechargeable with a built-in Lithium Polymer battery, so it takes no replaceable battery. Check the battery line for your model before you buy, since the size changes from model to model.
Find the battery line for your model
Look for the battery line in the tuner specs before you order a replacement. The Snark SIL-RED lists 1 CR2 battery, so that model takes a CR2 cell. The battery type field also names the cell, and the Snark ST-8HPT lists a Lithium Polymer battery there.
Know the battery types
Clip-on tuners use a replaceable battery or a built-in rechargeable battery. A replaceable battery comes out when it runs down: the Snark SIL-RED takes 1 CR2 battery, so keep a spare CR2 with the tuner. A rechargeable tuner has a built-in Lithium Polymer battery that charges over USB, and the KLIQ UberTuner-MAX needs no CR2032 replacements at all. The Snark ST-8HPT is rechargeable too, with no batteries to buy or change.
Swap a CR2 battery
Open the battery cover on the tuner and lift the spent CR2 out. Place a fresh CR2 in the same way round as the old cell, then close the cover and switch the tuner on to check the display lights. Keep a spare CR2 with the tuner so a flat battery does not end a session, and store spares where they stay dry.
Charge a rechargeable tuner
Plug the tuner into any USB power source with its cable and let it charge. The KLIQ UberTuner-MAX charges via USB, so you can tune again within minutes of plugging in. The Snark ST-8HPT is rechargeable too, with no batteries to buy or change. Unplug the tuner when the charge finishes, and keep the cable with the tuner so it is there when the battery runs down.
