3V 2 x AA Battery Holder Case Box with Leads

Pros: -on/off switch is useful for DIY projects
-there's screw hole for stabilizing the cover which's useful if you are using it on a toy for kids (screw not included)
-approx. 10cm of each wire

Cons: cover does fit the holder but click mechanism doesn't work. may get loose in time (here works the screw hole)
it's a stand alone power source there isn't any hole for mounting the power source to a board,tool or etc.

Other: It's ok for the price. works for the needed stuff. I used it as a power source for 20mw green laser without a problem.

Pros: Nice fit for batteries, decent leads & contacts, decent quality plastic, the on/off switch is a nice bonus.

Cons: Cover a bit difficult to secure properly, but it works. Drilled for a screw (not included) for applications where it 100% must stay on.

Other: If you need an enclosed holder for 2xAA batteries, get this one!

Pros: It holds very well AA batteries. Also 14500 It has an "on off" switch, VERY USEFULL It is closed, so for places with dust is quite good. Plastic quality is better than expected

Cons: Nothing special Maybe wires could be better.

Other: If you need a case for AA batterys and you are choosin a closed box or one opened, choose this closed one, really good

Pros: the springs are firmly mounted and the body has solid construction, plastic is solidly thick enough with just enough flex so it is not too brittle, it switches with just the right amount of force

Cons: did not come with screw to lock the cover closed there no easy way of firmly attaching it to my project (no mounting holes and the switch is placed so I cannot mount glue the back to anything the wires could be a bit stonger and there could be a methond to prevent stress on the solder connection

Other: despite my cons this is actually better quality than I was expecting. a few design adjustments and it will be perfect.

Pros: Very easy to use. Very practical power source for small electronic components. It has switch which is useful if you don't need "always on" power supply unit. It's under $2 so it's cheap. Build quality is good for price you pay.

Cons: Nothing to report, work fine.

Other: Great purchase and great solution for small power supply unit.
