After a battery has been charged, allow it to sit for several hours then
check the voltage to determine if the battery kept its charge. Some re-
duction in voltage is acceptable. However, if the battery falls below 13.0
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 charg-
ing.
• 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
electronic/electrical device. If your device is not protected for im-
proper 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, try to keep the panel clean.
