Cans and leads
Cans coated with a thin layer of 99.99% pure tin. Tin is a soft metal and can be scratched with a fingernail or any hard object. For this reason, it is possible for the surface of cans and solo cans to be scored, scratched, and scuffed during fabrication.
The tin coating methods used do not allow the cans to be evenly coated with tin, so there may be areas of uneven coating with different thicknesses, color shades and smoothness of the coating on the surface of the cans.
Tin is easily oxidized by contact with the sweat of the hands, and the color becomes darker.
Permissible storage temperature of cans - from 0°C to +50°C. Long storage of cans at low negative temperatures can change the crystalline structure of tin and become brittle, do not allow long storage and transportation of cans at temperatures below -10°C.
Use a soft cloth and any alcohol-containing liquid to wipe off sweat stains on the cans.

Battery and replacement
The device uses a 14500 size, 3.7 volt, lithium-ion battery with no leads and no protection. Batteries with protection may be several millimeters longer than the standard AA battery holder length, so we do not recommend their use. Batteries must not have wires. An example of such a battery is EEMB LIR14500:
To replace the battery, unscrew the M3 screw that holds the battery cover and with slight twists from side to side, not more than 15 degrees on either side, pull the cover out and remove the old battery. Insert the new battery, put the cover back on and tighten the screw. Be careful, if you rotate the cover too much, you may damage the contact wire soldered to the inner edge of the can and the e-meter will malfunction. If the battery is held to the board with plastic wire ties, secure it with a new tie before closing the can.
WARNING! When shipping by EMS or DHL, the batteries are removed from the device because shipping regulations prohibit shipping devices with rechargeable lithium-ion batteries. You need to buy such batteries in your country and insert them when you receive the device.
