Storing TekCharge MP1820
Lithium ion batteries must be used consistently for maximum performance . Therefore, if you do
not use the battery often, once a month you should discharge and recharge the battery to 40% (if
it will be transported) or 70% (for long term storage), and store it in a cool and dry environment
at a temperature between 50° and 86° F (10° and 30°C) . You may permanently damage your
battery’s capacity by storing the battery without any capacity in the cell . It is important that
you do not leave the battery in the interior of a vehicle parked in the sun, or exposed to direct
sunlight for extended periods of time .
Prolonging Battery Life
Extreme heat and cold will affect your battery’s performance . At temperatures above 80°F
(27°C), the battery will discharge more quickly, and in colder temperatures, the battery won’t
charge well . Therefore, it is recommended that the battery is used at room temperature, or
between 68°F to 77°F (20°C to 25°C) . The battery must be used at temperatures between 32°F
to 104°F (0°C to 40°C) . It is not recommended that the battery is charged in temperatures above
104°F (40°C), and the battery capacity may be permanently damaged if you use your battery in
temperatures higher than 140°F (60°C) . You may damage the battery even more if you charge
the device in these temperatures . You may find that using the battery in a very cold environment
decreases the battery capacity . Unlike the effects of a hot environment, this is a temporary
condition . Once warmed, the battery will return to its previous capacity .
