Rechargeable Lithium-Ion Batteries

[Woody Sound]

I bought a set of L-I rechargeables with charger for my wife's Shure wireless mic. I have read so many different opinions about how/when to charge them. Charge them as soon as you're done no matter how long or short they were used, don't charge them until completely drained, etc etc. Any advice from the collective wisdom here? Tnx.

I have a lot of these, of different sizes/shapes. In my somewhat limited experience, and from what I've read, they should not be completely drained, nor kept at 100% for long periods. I tend to charge them after use, if I've used them for very long, to make sure they're ready for the next time, but I don't charge them for long periods, or leave them on the charger. But I'm not an expert on the subject, just a random guy on the internet.

Thanks. Her regular gig is one hour, a few times a week. I think I'll just try a pair in her mic and see how many days she gets on one charge, and go from there. This is what I bought:

These are interesting. Lithium ion cells are 3.7v nominal so these batteries are obviously stepping down the voltage with internal electronics.
Only downside is that they will maintain 1.5v until the circuit detects low cell voltage and cuts the power. This means your device "battery level" indicator will read "full" until a sudden power down event. Might matter, or might not, depending on your use case!

Edit : I should point out the above is speculation as I've not seen the batteries in question.
