We see batteries being installed everywhere on a daily basis.

What are the risks with regards to charging batteries and the location of batteries in close proximity to electrical installations?

We are know that batteries become a high risk when being charged because of the hydrogen, but at what point do you need to be aware of the dangers?

Do we have to take the type of battery into consideration?

Do you have to take any precaution when installing:

1/ Sealed batteries, which are suppose to be sealed and do not release any hydrogen while charging.

2/ Deep cycle, which have an outlet but do not release huge volumes of hydrogen while charging.

3/ other types which are no sealed.
