I finished a dorcy laser yesterday. I like rechargeable batterys because I can use them as much as I want and not have to pay money to buy another battery.
Do they make these battery types rechargeable?if so Where can I buy one?
I'm using a DealExtreme RCR123 & charger with my DIY Dorcy (SKUs 3404 and 998).
I get more current to the LD than I did using a regular alkaline, but I chose my resistor while using the rechargeable.
If you're using a 10 Ohm resistor with a Dorcy and a GB diode, you've got lots of headroom - you should be okay with that. (You are using a capacitor across the diode, right?)
Really, at RS? I'd have believed rechargeable lithium AA cells - CR123s seem a little obscure for them, but maybe so.
Things to consider:
1. Some are 3.0V, some are 3.6V - depends what you want.
2. Some are "protected", meaning they shut off before getting discharged past the point of doing themselves damage. Some are not.
3. At DX, if you can stand the wait, it's gonna cost you like 1/3 of RS.
I checked out there rechargeables at radioshack but they are only 400mah. Thats really poor quality for a lithium rechargeable. I am currenlty looking at ultra fire CR123A lithiums. They are protected but 3.6 volts. Can they still be used in my dorcy jr? It is protected, but people say that it is about 1 mm longer than unprotected. I'm gonna get the protected, but will it still fit in a dorcy?
