Design the battery enclosure to prevent accumulation and concentration of hydrogen gas in “pockets”
at the top of the enclosure. Vent the battery compartment from the highest point to the outside. A
sloped lid can also be used to direct the ow of hydrogen to the vent opening.
CAUTION
To reduce risk of injury, charge only deep-cycle lead acid, lead antimony, lead calcium, gel cell or
absorbed glass mat type rechargeable batteries. Other types of batteries may burst, causing personal
injury and damage. Never charge a frozen battery.
PERSONAL PRECAUTIONS
• Someone should be within range of your voice to come to your aid if needed.
• Keep plenty of fresh water and soap nearby in case battery acid contacts skin, clothing, or eyes.
• Wear complete eye protection. Avoid touching eyes while working near batteries. Wash your hands
with soap and warm water when done.
• If battery acid contacts skin or clothing, wash immediately with soap and water. If acid enters an
eye, ood the eye with cool running water at once for at least 15 minutes and get medical attention
immediately following.
• Baking soda neutralizes lead acid battery electrolyte. Keep a supply on hand in the area of the
batteries.
• NEVER smoke or allow a spark or ame in vicinity of a battery or generator.
• Be extra cautious to reduce the risk of dropping a metal tool onto batteries. It could short-circuit the
batteries or other electrical parts can result in re or explosion.
• Remove personal metal items such as rings, bracelets, necklaces, and watches when working with
a battery or other electrical current. A battery can produce a short circuit current high enough to
weld a ring or the like to metal, causing severe burns.

WARNING: WORKING NEAR LEAD ACID BATTERIES CAN BE DANGEROUS. BATTERIES
GENERATE EXPLOSIVE GASES DURING NORMAL OPERATION.
