What is the easiest way to lower the DC output (reduce voltage)?

If this is battery operated, then most likely it will work fine on 5 volts. If you are worried about the exact voltage, use a adjustable regulator to make 4.5V. Keep in mind that a linear regulator dissipates the difference in voltage times the current as heat. If the radio draws 100 mA, for example, then a 5V linear regulator would dissipate

Power issue with PCB board using a DC-DC converter

Look at the voltage of the coin cell using a DVM and see how rapidly it falls. It seems like the module would run at 1.8 V, so you might consider DC-DC stepdown to 1.8V which would lower the drain on the battery. LEDs could be powered from the battery directly, unless they are blue or white.

Revive Your Dead Lithium Battery Pack with These Repair Tips

Even if each individual cell in the pack has been properly soldered and repaired, a weakly balanced battery with uneven voltages can still lead to an unreliable power source. To ensure that the entire battery pack works optimally, it''s important to balance the cells within it. BMS is one of the most common battery balancing systems. It can avoid issues such as

4 FAQs about [Refitting battery voltage from discarded power board]

Can a depleted primary cell battery be used under load?

Typical depleted primary cell batteries will provide a higher voltage under no-load than under load, so getting that initial 330 mV at start-up is not difficult. The standard application circuit from the datasheet is thus: This is be pretty effective in sucking residual energy out of your depleted batteries down to nearly the last drop.

What if a non-rechargable battery is low on power?

When non-rechargable battery B1 is low on power, S1 and S2 simulatneously switch to path 1-3 (in mechanical terms it is DPDT-switch). Threshold could be residual voltage. I do not know what is optimal value, but I guess when it drops below 0.6v (without voltage), we can declare the battery dead (it can switch back at some higher voltage, say, 0.7v.

Can electrical engineering Stack Exchange harvest energy from old batteries?

Electrical Engineering Stack Exchange Harvesting energy from old batteries? Old batteries (I mean AA, AAA -sized 1.5v ones) usually have some residual energy, which can be used, for example, to charge mobile phones/pads.

What if a battery voltage drops below 0.6V?

Threshold could be residual voltage. I do not know what is optimal value, but I guess when it drops below 0.6v (without voltage), we can declare the battery dead (it can switch back at some higher voltage, say, 0.7v. These values are arbitrary, optimal old-battery energy-harvester may need them lower.).
