Lithium batteries do not suffer from “battery memory” therefore
you do not need to fully charge to 100% or fully discharge to
0%. Complete discharge of batteries should always be avoided.
Shallow discharge is preferable, i.e. recharge at 20% if
possible.
Battery Safety Guidelines
• The area in which the units are charged should be clear of
debris and combustible materials or chemicals.
• Improper battery use may result in a fire, explosion, or other
hazard.
• To charge the mobile device battery, the battery and charger
temperatures must be between 0°C and +40°C (+32°F to
+104°F).
• Do not use incompatible batteries and chargers. Use of an
incompatible battery or charger may present a risk of fire,
explosion, leakage, or other hazard. If you have any
questions about the compatibility of a battery or a charger,
contact Tablet Technologies support.
• For devices that utilize a USB port as a charging source, the
device shall only be connected to products that bear the
USB-IF logo or have completed the USB-IF compliance
programme.
• Do not disassemble or open, crush, bend or deform,
puncture, or shred.
• Severe impact from dropping any battery-operated device on
a hard surface could cause the battery to overheat.
• Do not short circuit a battery or allow metallic or conductive
objects to contact the battery terminals.
• Do not modify or remanufacture, attempt to insert foreign
objects into the battery, immerse or expose to water or other
liquids, or expose to fire, explosion, or other hazard.
• Do not leave or store the equipment in or near areas that
might get very hot, such as in a parked vehicle or near a
radiator or other heat source.
• Do not place battery into a microwave oven or dryer.
