Charging Lithium Batteries

[Johnloudb]

I been charging Alkaline 9v batteries with no problem, done slowly so nothing explodes. I have exploded some 9v batteries by accident, when they came in contact with a piece of metal, shorting them. No big big deal ... just popped like a fire cracker and no mess.

So, now I bought some lithium 9 volts. When they are dead I want to charge them like I did the alkaline batteries. Anyone tried this? Just curious if there are issues with doing this. Yes, they have Lithium-ion rechargeable 9 volts but they cost a lot more.

Will it work? Anything I should be concerned about?

Lithium? Very reactive metal. I would not mess with it. Lithium batteries have a reputation for catching fire if mistreated (or even sometimes when not mistreated). I suspect (a chemist can confirm - SY?) that lithium fires are difficult to put out because it reacts with both water and carbon dioxide.

Okay, thanks for the reply. I will be very careful if I decide to try it, and charge it in a metal box.

the sort of heat you are looking at here will melt a lot of metal boxes. just buy rechargeable lifepo4 batteries

There is a reason that everything today uses Lithium Ion batteries, because batteries that use lithium metal do not recharge well. They can become very unstable, so much that you don't really have to do anything wrong for them to have issues.Some cell phones in Japan used lithium metal anodes in the early 90s and were outlawed later after a few caught fire while people were using them.
There are good reasons to use a primary lithium battery, but much better solutions if you want to recharge them

Okay, Thanks. I won't recharge them. I'll just stick to recharging alkalines for now.
