Can using a low-cost device drain a rechargeable battery?
I own several units of nearly identical wireless mini keyboards featuring back-light. They are fairly inexpensive and lack distinct branding, as many Chinese manufacturers seem to replicate the design with minimal modifications. These keyboards tend to fail prematurely for my preferences: even with 1020 mAh batteries, they often last only a day under intense use. I conducted an extensive search and eventually purchased two units with 1400 mAh batteries. The performance gap was remarkable—one, fully factory-charged, lasted 14 days, whereas the other, used under heavier strain, lasted just 11 days. After recharging them using a high-end PC power supply and a USB micro cable, I was still unsatisfied. Under extreme conditions, both lasted only 3 and 5 days respectively. My concern is whether these budget models have faulty charging systems. If I were to invest in a professional BL-5C charging device, could it enhance the lifespan of my batteries?
Affordable batteries, inadequate charging systems, etc., etc.
Pay low prices for bad goods, receive substandard items.
It seems in my country very few people sell them, and I don't wish to purchase a low-quality or weak one.
