Ventilated battery box

While these types of batteries are charging, explosive hydrogen gas is produced (remember the Hindenburg?). Because of this danger, many folks keep their batteries outside their homes with plenty of ventilation. While ventilation is important, batteries do not like the cold, so just sticking them outside without protection is a great way to damage them. They prefer a temperature range between 32 and 80°F.

Ventilation fan draws in air

Batteries need to be in a well-ventilated battery box so they are protected from rain, snow, and cold. Also, be sure to keep your batteries clean, ventilated, and away from flames or sparks. Our box is located in the utility room inside our house. It has a vent tube leading outside and a cooling fan from a personal computer case that draws air into the box, which then pushes the hydrogen gas outside.

To ventilate your battery box, do not use any old fan you might have lying around. Most fans use older motors with internal parts that spark, which could detonate the hydrogen gas. PC cooling fans use induction motors with no sparking parts. Position your vent tube near the top of your battery box, because hydrogen gas is lighter than air and will collect at the top of the box.
