Is there a rechargeable lithium battery for the FWB 90 pistol?

Is there such a thing as a lithium rechargeable battery for the FWB 90 pistol?  If not, how long does the standard battery last?

Thanks,

David Enoch

 well after looking i pulled my first post 

i did find a rechargeable battery  

https://www.lowes.com/pd/Exell-Battery-Rechargeable-Alkaline-A220-504A-Camera-Flash-Batteries/1000682983

it is used in other pistols and cameras and who knows 

how long they last, well sitting the the gun it seem years but if you shot 100 pellets a day i don't know 

you know they list those as rechargeable but that is the same battery that everyone lists, so that's an unknown

Any idea how much current the gun draws?

power consumption in electronic terms no but it's very very little, a battery will last for 5 years i'm thinking

If a battery will last that long, no need for a rechargeable.

Battery will last 5000 shots according to the manual.

I don't think there is a lithium equivalent for the Eveready 504.

Well David if you shoot it a 100 time a day or a few times a year the battery life will vary but in a resting condition the battery should be fine 

mine i have shot maybe 100 times in the time i have had it, so the battery will go bad before it is drawn down in power 

of course never cock the pistol before you check battery power or in my case just pull the trigger and fire the solenoid 

cocked pistol, bad battery can be a problem there is a work around but i forget what it is, i would have to find that old post

A CR123/16340 will fit it seems(16.5 X 34 mm) but it is 3.7 volts. Got a soldering iron? 😲

Bigbore what would the soldering iron be used for 

the batteries that are used are 15 volt they don't need changing that often but are over ten dollars each and they fit in the grip frame in there place, so there is no need to invent the wheel 

so what are we soldering

 I was reading the manual from the provided link and I though it said the batteries were 1.5 volt. A 15 volt cell? Gotta link? I've never seen a single cell with a voltage that high.

That is why it's called a battery. Cell is singular, battery is plural. If you'll use the terms correctly, the whole deal makes more sense.

2v cell +2v  cell +2v  cell +2v  cell +2v  cell +2v  cell = 12v lead-acid car battery.

Continue adding in series until the desired voltage is achieved.

Alkaline or carbon zinc (not an exhaustive list) produce 1.5v PER CELL, meaning that a 9V battery (smoke detector type) must contain 6 small cells.

GWH, I know. Another term that isn't used anymore is "pile". Until the lithium batteries came along for RC, 9 volt was the highest voltage "battery" I recall seeing. The 15 volt battery is most likely 10 cells stacked since it is alkaline. I assumed the cylindrical battery was the typical single cell.

 That is a very difficult voltage to deal with in terms of battery supply. I think you were alluding to a work-around by inquiring about the current draw. If you were, it would be a worthwhile project for someone with the electronics knowledge, especially with the cheap price of custom PCB's. I would try to get it to run off a CR123 unless there was no way to drive a 15 volt gun component as efficiently as designed.

hey all we need to do is invent AC batteries and then we could throw a cascade multiplier in there 😉

 

David, batteries are susceptible to cell degradation via damage to the 1st or last cells in the series.

The smaller the cells, the more easily damaged,  through over-discharge and overcharging, and the fewer number of cycles available.

If there were a rechargeable, it might be a tease, and any benefits offset by the special charger required to avoid wrecking it.

 

Now... I wonder how many coin cells could be stacked before one ruptured...
