6. ENVIRONMENTALPROTECTIONREQUIREMENT
6.1 The requirement on Hazardous Substances in the materials should comply with MOTOMA’s
standard on HSF (Hazardous Substance Free).
6.2 The requirement on Hazardous Substances in the Products should comply with 2006/66/EC
and MOTOMA’s standard on HSF.
7. TRANSPORT
7.1 To ensure battery safety during delivery, SOC (State of charge) must be below 30% , inside
temperature of container could not be over 35℃. Product holder should be responsible for any
possible loss during delivery if above conditions cannot be met completely.
7.2 Inside temperature of container must be below 20℃if any client requires SOC above 35%,the
distance between battery master cartons not less than 10cm incontainer, and coercive air cross
ventilation system is required in container to ensure even temperature for each master carton.
Product holder should be responsible for any possibly accidental loss if above conditions cannot
be met completely.
8. WARNING!
Do not apply water, seawater or other oxidizing reagents to MOTOMA batteries, as this can
caused rust and heat generation. If a battery becomes rusted, the gas release vent may no
longer operate, and can result in explosion.
Do not over-charge MOTOMA batteries, If MOTOMA batteries are not fully charged after the
battery charger’s predetermined charging period has clasped, stop the charging process.
Prolonged charging may cause leakage of battery fluid, heat generation, and explosion. Be
sure to handle recharged batteries carefully as they may be not.
MOTOMA batteries contain a strong alkaline solution (electrolyte).If the skin or clothing comes
in contact with fluid from a MOTOMA battery; thoroughly washthe area immediately withclean
water from the tap or another source. Battery fluid can irritate the skin.
Do not connect more than 21pcs MOTOMA batteries in series, as this may cause electrical
