Pb Battery Safety; Liion, Lipo, Life Battreies Safety - GRAUPNER ULTRAMAT AC/DC EQ Operating Instructions Manual

◎ Pb BATTERY SAFETY

Pb battery needs to be charged every day. If the charged capacity of battery is dropped
below 50%, this battery might not be recharged. The average charge time of Pb battery
is 4~5 hours. Do not charge Car battery, the charger might get the serious damage

◎ LiIon, LiPo, LiFe BATTREIES SAFETY

1. Always charge the batteries that have Lithium ion or Lithium polymer mark and do not
charge the batteries that have Lithium mark. Failure to do so will damage the batteries
and may cause fire or personal injury.
2. Always charge the batteries that the cell voltage ( 3.3V / 3.6V / 3.7V ) is written
3. Ensure that the charger and battery are placed on a non-flammable surface whilst
charging.
4. Never charge Lithium ion/Polymer/Fe batteries inside a vehicle whatever the circum-
stances.
5. Always ensure that the charger is correctly set for the battery being charged, checking
both voltage and capacity. Be particularly careful if using a series/parallel battery pack,
or if using packs of different specifications with the same charger.
6. Never charge at a rate higher than that recommended by the cell manufacturer, this can
be very dangerous.
7. Do not leave Lithium ion/Polymer/Fe batteries unattended whilst they are charging. Mon-
itoring the batteries during charging is very important.
8. Always monitor the temperature of the battery being charged every few minutes. If the
battery becomes hot to the touch, disconnect it from the charger immediately and allow
to cool. Do not recommence charging until the battery and charger have been checked
for compatibility and the charger settings have been confirmed as being correct.
9. In the unlikely event of the Lithium ion/Polymer/Fe battery catching fire DO NOT use
water to attempt to put the fire out, instead use sand or a fire extinguisher designed for
electrical fires.
10. When used correctly, Lithium ion/Polymer/Fe battery packs are as safe as any other
type of rechargeable battery pack. However they do require different charge regimes
to the longer established Nickel Cadmium and Nickel Metal Hydride technologies and
have the potential of catching fire if severely mistreated.
11. If Lithium Polymer battery packs are short-circuited or severely over-charged elemental
Lithium may be deposited internally, and if the battery pouch is damaged this can es-
cape from inside the battery. If this occurs a fire may be caused, as elemental Lithium
is highly reactive when exposed to water or moisture, producing flammable hydrogen
gas and corrosive fumes. Elemental Lithium is not produced unless the battery pack is
severely mistreated, so in normal usage there is no likelihood of explosion or fire.
12. Lithium Ion/Polymer battery packs must NEVER be discharged below 3 volts per cell
(LiFe 2.0V) as this will result in damage to the cells. If the voltage is allowed to drop
below 3 volts per cell the battery voltage may seem to recover following a charge, but the
battery may not then give its full nominal capacity and a reduction in performance is likely
- allowing the voltage to drop below 3 volts per cell will invalidate all warranty claims.
13. Never charge Lithium Polymer battery packs at greater than 4.2V per cell, Lithium Ion
at 4.1V volts per cell or LiFe at greater than 3.7V per cell as this will cause irreversible
damage to the cells and will invalidate all warranty claims.
