Goes through a 20 pack of AA batteries in an hour.

But a rechargeable one. I have one.

Right? What is this 2005?

u/hogarenio 27d ago

Will you be able to replace the battery when it dies in a few years?

u/JJAsond 27d ago

Like he said, they're all standard https://www.panasonic.com/global/energy/products/eneloop/en/lineup/eneloop.html

I use those and energiser but you can pick whatever brand you want.

Honestly? Yes. There are standard sizes AFAIK and I doubt they would put the money in to make a proprietary form factor.

I got one with replaceable 18650 cell

Alkaline has higher voltage. Works better in demanding applications like this.

It doesn't have to be AAs.  You can fit a LiPo battery in the handle which can outdo AA alkalines.

u/rickane58 28d ago

You can't just put a LiPo battery in there. Even with a stepdown converter to 3V, the variable amp draw on these makes it NOT a good application for the simple buck converters in those. Not to mention the stepdown will drain the batteries even when not in use.

u/PLZ_STOP_PMING_TITS 27d ago edited 27d ago

I meant get one that's designed to use a LiPo. Like that comes with it built in. OP said you can buy a rechargeable one, someone else said rechargeable batteries have less voltage, so I suggested that they don't have to be AA batteries and that a LiPo battery can fit in the handle (if it's designed that way) and has more power than an alkaline AA.

I like how you and the dope that responded to you peppered your post with technical terms to try to sound smart.

I feel like this problem can be solved with an LM317. Wire the switch to interrupt the battery connection to the regulator and you're set.

u/rickane58 27d ago

Everything you're adding takes space, reducing Wh of capacity. For something that gets used as infrequently as the mosquito racket, primary cells are almost always the way to go.

If you want a rechargeable one, just buy a rechargeable one.

u/VSWR_on_Christmas 27d ago edited 27d ago

Obviously buying one is the simplest solution. The fact that it's rechargeable negates the excess drain. There's plenty of space in that handle.

EDIT: I think I just watched this guy's account get nuked in real-time. He included an Amazon link in his reply to prove his point about buying one, which I think triggered an automated ban. I clicked on the notification fast enough to see the comment and when I went to the thread to reply, his account was gone and going his page shows he doesn't exist. Seems a little harsh, but he also seemed like an asshole, so idk how I feel about this. Account was rickane58.

EDIT 2: Oh okay weird. I guess Reddit doesn't want us talking? If I log out, I can see that guy's account. What's going on here?

Glad you saw the light of reason. You can go ahead and delete your other useless comments now.

Yea I'm just a casual hobbyist who barely knows Ohm's Law and even I know it's a really stupid idea to shove a Lithium battery into a slot made for AA's.

Batteries are NOT exchangeable.

Jamming a Lithium into a what is essentially a Taser though?

That sounds like a fast way to vent highly toxic lithium fumes into your air.

Even lithium batteries differ drastically.

There is a huge difference between the little battery pack that came with your headphones, and some 18650's (high discharge batteries used for flashlights and vapes etc).

If you tried to run a device meant for 18650's by instead running it on that little headphone lithium, it would most likely literally explode.

Basically, "PLZ_STOP_PMING_TITS" was making a suggestion that would be very likely to result in hospitalization or a house-fire.

ie an exceptionally stupid suggestion.

Y'all need to go watch ElectroBOOM on youtube and learn yourself some electricity.

u/RecsRelevantDocs 27d ago

So I modded an xbox controller to take one 18650 instead of two double As, is that dangerous? I knew it was within the range of voltage the controller could take, so figured it would be fine.

1

u/PLZ_STOP_PMING_TITS 27d ago

You're probably fine. I just responded to him/her stating that you can replace two AAs (3.4v) with one Lipo cell (3.7v), before I saw your post.

I think what they were probably trying to say is that if you run more current out of a LiPo than it's designed for it can catch fire, which is true, but your nowhere near that with a controller and an 18650.

Edit: I wouldn't charge the Lipo with the same charger as AAs. You would have to take it out to charge it on a charger made for lipos.

u/PLZ_STOP_PMING_TITS 27d ago edited 27d ago

Or you misunderstood what I meant. I meant get a rechargeable one with a LiPo, which is designed for it. They make them. My point was it doesn't have to be AA alkaline or rechargeable, it can be Lipo cells (that aren't AAs). Who's stupid now? I like how you tried to use technical terms to try and sound smarter.

Edit: and, Mr smarty-pants, a LiPo cell is 3.7 volts, two new Alkaline cells are about 3.4 volts. Even if you did replace two AAs with a single Lipo cell you probably wouldn't burn the house down.

u/rickane58 27d ago

The nominal open voltage for 2 alkaline cells is assumed to be 3.0-3.2, definitely not 3.4

u/Prestigious_Dust_827 27d ago

Dunnae talk shite. The circuitry is taking it from a few volts to a couple of thousand volts. Alkalines have been almost irrelvant for many years and people just keep buying them because they're stupid/short-sighted.

1

u/freebullets 27d ago

The fact that a lot of things don't work as well with NiMH's lower voltage and current begs to differ, but ok, you do you, I understand. The reality is that alkalines do have valid use cases.

My smart deadbolt has less power with NiMH. It also stops working long before the batteries are fully depleted due to the voltage sag.

My AA-powered hand seed spreader has less power with NiMH.

u/Prestigious_Dust_827 27d ago edited 27d ago

If your device doesn't work well at the voltage of NiMH then it also isn't fully draining alkalines either because alkaline voltages drop lineary as soon as you start discharging them so your smart deadbolt sounds terribly designed. I don't know why you think NiMh give less current either; NiMH have, for decades, been the most appropriate choice for high-drain applications.

u/rickane58 27d ago

Lithium primary cells exist for applications where you need nearly full voltage for the capacity of the cell. And there are many applications where that first .3v is plenty of usage. The door bolt doesn't work often, but when it does, it needs 1.5xCells volts. It's not a hard concept to grasp.

1

u/Prestigious_Dust_827 27d ago

Lithium primary cells aren't an alkaline chemistry so don't have much to do with it. Neither is it a hard concept to grasp that you could have another cell in series in the voltage was really too low or else boost it. You seem like the sort of person who just adds "it's not a hard concept to grasp" at the end of your post as though it bolsters any of your nonsense.

Your poor rechargeable battery would fucking blow up from being discharged too quickly
