Can rechargeable batteries last for 3-4 years with 24h use at 5-15 volts?

Click For Summary
SUMMARY

The discussion centers on the challenge of finding rechargeable batteries that can last 3-4 years under continuous use (24 hours a day) while operating at 5-15 volts. Participants highlight the limitations of existing battery technologies, such as LiPo and lead-acid batteries, which typically offer 300-500 charge/discharge cycles and a lifespan of 3-5 years. The need for batteries that charge faster than they discharge is emphasized, but the lack of clarity regarding current requirements complicates the search for suitable solutions. Suggestions include considering standard 1.5V rechargeable batteries or capacitors as alternatives.

PREREQUISITES
  • Understanding of battery chemistry, specifically LiPo and lead-acid technologies.
  • Knowledge of voltage and current requirements for electronic devices.
  • Familiarity with charge/discharge cycles and their impact on battery lifespan.
  • Basic electronics principles, including the role of capacitors in power supply.
NEXT STEPS
  • Research the specifications and performance of LiPo and lead-acid batteries for long-term use.
  • Explore the use of capacitors as a potential alternative to batteries for specific applications.
  • Investigate the latest advancements in flow battery technology for compact applications.
  • Learn about the implications of current draw on battery selection and device design.

A 1.5VDC battery with a low enough discharge rate will last for a few years, like the motherboard battery in your computer.

Any rechargeable battery won't do in the condition of constant use 24/24h, I need it to last for at least few years that's why I asked the question in the first place, and somehow people started being very negative instead of understanding what I was saying and being constructive

For how long battery can work depends on its capacity and the current you need to draw, do you understand that much? If you need 1 nA current, 1 Ah battery will last 32 years. As long as you don't tell us more details you are wasting your time and our time.

Excellent point.
Go to the first page, read the description of what I'm doing and you'll understand why i need a rechargeable battery.
I do not need a source of energy, I need a solution to the delay problem and rechargeable batteries seemed to be a simple answer to it.

That's enough trolling.
