Disappointment: Household Batteries, Chargers & Accessories

I bought these batteries because we use UV flashlights every night to to go home outside and kill the scorpions. In other words, we heavily use both AAA and AA batteries. It seems like a good idea to buy rechargeable batteries, however. Surprise! The amount of light we get is the same as non-rechargeable batteries that have been used for several days and need to be replaced. I don't recommend them. They advertise them as durable. We just tried them and they looked really bad the first night. I don't recommend them.

Pros

🔋HIGH CAPACITY & LONG LIFE: 3200mAh 3.7V batteries, higher capacity than other traditional batteries. LOW SELF DISCHARGE technology allows the batteries to retain an 80% charge after 12 months of non-use. Premium batteries can be recharged up to 2000 times with minimal loss of performance. Instead of disposable alkaline batteries save money for you and save energy for the environment (NO charger)

Cons
