10.ʹʱעBattery handling precautions

Ϊֹؿܷй©ȡըעԤʩTo prevent battery from leakage, heat, explode; please take the precautionary steps carefully.

    Warning:

l               Ͻؽ뺣ˮˮУ治ʱӦĻСNever directly connect batteries to a direct power source.

l               ֹȸԴԣ𡢼ʹúáNever short circuit batteries

l               ʱѡӵרóDo not strike or drop batteries.

l               Ͻߵʹõ. Do not charge or use batteries with the positive and negative terminals reversed

l               ϽֱӲԴ. Do not apply water, sea water or other oxidizing agents to batteries.

l               ֹضڻ. Never solder lead wires directly on to batteries.

l               ֹýֱӵ·. Never dispose of batteries in fire or heat them.

l               ֹ,緢Сһ. Never solder lead wires directly on to batteries, nail through the battery with any sharp objects.

l               ֹṳ̂ص. Store batteries in a dry place and within the recommended storage temperature range.

l               ֱֹӺӵغöӻ̴. When charging the battery, use amblygonite battery charger only.

С    ! Caution

l               ֹڸ£ȵ»ȵУʹûõأܻعȡʧЧ̡Prohibited at high temperatures (very hot sun or in a hot car) to use or storage the battery, or the battery may cause overheating or fire or function failure, shortened lifetime.

l               ֹǿǿųĵطʹ,ƻذȫװ,ȫ. Avoid to use the battery in electrostatic and magnetic place, or safety devices easy to destroy,to rise unsafe risks.

l               طй¶,Һ۾,벻Ҫ,Ӧˮϴ۾,ҽ,˺۾. If the battery leaks and the electrolyte in your eyes, do not rub first, apply clean water wash the eye first, and immediately contact the local medical facility.

l               طζ,ȡɫλʹá桢гκ쳣,شװû벢ͣ. If the battery gives off an odor, fever, discoloration, deformation in the usage, storage, charging, immediately cut off the battery from the device or charger.

l               缫Ū,ʹǰӦøɲĨ,ܻᵼ½ӴʧЧ. If the electrode dirty, wipe with a dry cloth before use, or it may cause functional failure of poor contact.
