Review on 🔋 20-Pack GEILIENERGY Solar Light Batteries - AAA 1.2V 600mAh NiCd Triple A Rechargeable Batteries for Garden Solar Lamp Lights (Green Color) by Kevin Reyes

I bought these to replace some old radio shop batteries in an old pair of wireless headphones. I was sure that using a new type of battery in a charger designed for NiCd batteries was not a good idea, so I replaced the 300mAh 1.2V NiCd batteries. The old batteries gave me about 20 minutes of listening time with a good one Volume. These new ones allowed me to keep listening until I got bored (I think I've gotten too used to being limited by battery life). At first I was afraid that the built in charger of this wireless headset wouldn't charge them properly as it didn't charge initially. But after removing and reinstalling the batteries and trying to charge them, everything was fine. But I could easily listen at high volume on my wireless headphones for over 2 hours, which was impossible even with old batteries when new. The batteries I received look exactly like the picture despite what other reviewers have said and have 1.2v 600mah written directly on them.
