How to use AAA battery in parallel to increase current.

I get a lot AAA 1.5V battery from my friend. If still store them, will not have any helpful.
Now I have a wall clock which use AA battery size. So cannot use with them.
But it not hard over than our endeavor.
We need to use AAA battery holder. But I cannot buy it in any store. Most is AA size only.

I’ve seen friends of mine soldering wires directly to the battery terminals. He tell me, we can solder them but must fastest. A general battery not like over heat.

This way is easy and cheap.

Do not need holder battery

Therefore I also soldering them as Figure 1 you will see that I connected wiring in parallel to increase current is doubly times. By positive to positive and negative to negative terminals. It cause same voltage at 1.5 volts.

two battery on parallel cause high current application
Figure 2 two battery on parallel cause high current application.

Then we connected wiring to the wall clock battery terminals. As Figure 3

Lastly, time passes for 6 months, it still works well. We will can use AAA battery by no holder but it is really useful.

An alternative approach: take a piece of dowel (or suitable square sectioned piece of wood) and cut to approx 1/16″ to 1/8″ shorter than the full length of an AA battery. Wrap and solder 18-24 gauge wires to the pins of two metal pushpins (the round, mostly flat type, without plastic cap). Push these into the ends of the dowel. This is your dummy battery, so you don’t need to solder the device you’re powering. To make a battery box, you can take strips of aluminium cut from a drink can, or better, find copper tape or strips (sometimes found… Read more »
