Battery adapter from AA to D

[aparadafoto]

Hi, I own a Sony ICF 2010 and it takes three D size batteries. I live in Argentina and these type of batteries are very costly. I was thinking of buying three adapter cases D size that take a AA battery inside with AA rechargable Eneloops inside (like this https://www.amazon.com/LampVPath-Ba...-2-spons&sp_csd=d2lkZ2V0TmFtZT1zcF9hdGY&psc=1).
My question is if the use of these this D cases with AA inside will be OK to use in this particular Sony model.
Many thanks!

- First, it should work. I use holders like that, but I do not have that particular radio.
- Second, the voltage will probably be 1.2v from each battery using rechargeable versus 1.5v from alkaline.
- Third, one can purchase “D” holders that take two AA batteries instead of one. By adding that extra battery it will increase runtime. Ensure you insert the batteries in the same direction (parallel), so as not to increase voltage. Thus, the voltage will still be around 1.2v, but the Ah will almost double. Use the same battery brand and age when you do that, versus mixing.

The single “D” holders sometimes came with Panasonic AA rechargeable. I later found the generic two AA holders and sold the others. They may make something now that holds three AA, but unsure if that will fit in your radio. Some devices have more space in the battery compartment, while others have less.

Many thanks for you very clear and generous reply !
I'll do that. In fact, Amazon carries D holders for three AA batteries, not sure I can find them here in Argentina though ....
Thanks again!

* Remember - Even if you purchase a holder that can take two, or three, you could use one AA battery. Some devices pull a lot of energy while others not as much such as an LED light. For extended operating periods, it may be suitable to use three.

I began using rechargeable batteries over two decades ago. I get around 8-10 years out of the Panasonic/Eneloop batteries before they wear down too much. I use a permanent marker and write the year of purchase on the battery. This also helps me to not mix different year/aged batteries.

Yes. do I have some Eneloops from 2011, and they still work perfectly in my flashes (I'm a photographer). Greta advice. My initial worry was because I know this particular Sony radio requires 4.5V, and three AA batteries would be 3.6V ....

Devices can typically work within a voltage range. Some rechargeable batteries can initially supply more than 1.2v. If a device is losing memories or operating erratically, it can definitely be a voltage and or current issue.

My older worn down batteries are relegated to remote controls used around the home. Thinking further, I still have/use AA batteries older than a decade.

you might be able to adapt a larger capacity lithium ion / polymer battery 3.7 to 4.2V range (nominal) to run that radio and have the option to charge via USB.

This board charges at a 500 mAH rate.

SparkFun LiPo Charger Basic - Mini-USB

If you need to charge LiPo batteries, this simple charger will do just that. It is designed to charge single-cell Li-Ion or Li-Polymer batteries. Check the datasheet below to see if it will work with your battery. The board incorporates a charging circui

Yes, that would be the best solution but I live in Argentina and cannot import batteries. A similar set here costs about $180 !
