volts, recharge it for a longer period of time. If this does not improve
the charge, the battery is most likely defective and should be replaced.
Monitor your battery voltages frequently, charging when necessary,
and you will extend the life of your battery.
Additional Notes
• Do not expose the battery to moisture or rain.
• Do not drop, hit or abuse the battery — it may break and expose the
contents, which are highly corrosive.
• Do not short circuit battery terminals. Some batteries are protected
with self-resetting fuses, but short circuits may still cause severe dam-
age to the battery.
• It is normal for a battery to become warm to the touch during charging.
• It is normal for a battery to “self discharge” during prolonged stor-
age. Always fully charge a battery prior to storage. While in storage,
periodically check the batteries with a voltmeter to ensure they have not
discharged below a level that may cause permanent damage.
• Always store in a cool, dry location.
• Keep batteries away from fire and do not incinerate — they may
explode.
• Under no circumstances should you attempt to open the battery case.
• Always observe polarity when connecting your battery to any electron-
ic/electrical device. If your device is not protected from improper battery
hookup, you may cause severe damage to the electronic circuitry. The
positive terminal may be indicated by a plus (+) sign or red mark. The
negative terminal may be indicated by a minus (-) sign or black mark.
• The effectiveness of the solar panel can be reduced if it is dirty or
scratched up. For best results, keep the panel clean and in good condi-
tion.
