The battery pack has positive and negative poles. If the battery pack does not smoothly connect

with a charger or operating equipment, do not force it; check the polarity of the battery. If the battery

pack is reverse‑connected to the charger, it will be reverse‑charged and an abnormal chemical

reaction may occur. The battery may generate heat or smoke, rupture, or burst into ﬂame.

• Do not touch a ruptured and leaking battery!

If the electrolyte liquid from the battery gets into your eyes, wash your eyes with fresh water as soon

as possible, without rubbing your eyes. Go to the hospital immediately. If left untreated, it may cause

eye‑problems.

• Do not charge the battery for longer than the specied time!

If the battery pack has not ﬁnished charging even after the regulated time has passed, stop it. The

battery may generate heat or smoke, rupture, or burst into ﬂame.

• Do not place the battery pack into a microwave or high pressure container!

The battery may generate heat or smoke, rupture, or burst into ﬂame.

• Keep ruptured and leaking battery packs away from re!

If the battery pack is leaking (or the battery emits a bad odor), immediately remove it from ﬂammable

areas. Electrolyte leaking from battery can easily catch on ﬁre and may cause the battery to

generate smoke or burst into ﬂame.

• Do not use an abnormal battery!

If the battery pack emits a bad odor, appears to have different coloring, is deformed, or seems

abnormal for any other reason, remove it from the charger or operating equipment and do not use it.
