"I think this is a great way to store rechargeable 9V batteries and minimize risk of fire"
(New Jersey, USA)
I am always worried about storing 9V batteries, because I think they can cause a fire if the terminals touch something. This is an excellent way to store 9V batteries without fear for starting a fire - I actually store the batteries with the terminals facing the plastic bottom of these storage units, so the terminals are not even exposed. I have 12 rechargeable 9V batteries, and I bought 3 of these containers to store the batteries. They work well.
