Review on 🔋 Tenergy Solla AAA Rechargeable NiMH Battery, 600mAh Solar Batteries for Outdoor Solar Lights, Patio Lights, Non-Leak, Exceptional Outdoor Resilience, Long-Lasting Performance (5+ Years), 12 Pack, UL Certified by Elizabeth Pushkina

I'm sure all the positive feedback is coming from people who have just installed these batteries. I also liked them for 4-5 charges, and then they won't hold a charge. Then I noticed that these are nickel-cadmium batteries. Of course they are free of charge! The seller didn't lie. But ALL NiCADs have memory, which means that if you charge them before they are COMPLETELY dead, the remaining charge is the maximum they will hold from that point on. After a few charges, you'll be left with nothing. Little did I know that SOMEBODY still sells nickel cadmium batteries as far as new nickel metal hydride batteries go. These are disposable batteries - they definitely won't last the 5+ years that Tenergy claims. I have EBL and Revain Basics and since they are NiMH batteries they hold many, many charges.
