Challenge Electronics’ IP-rated battery holders provide a low-profile form factor with a watertight seal. Designed for AA and AAA batteries, these holders feature a sleek and easy-to-integrate design ensuring waterproof mounting under the harshest environments to save time in the design cycle.
A lot of electronic devices these days are designed to be sealed plastic enclosures – and if they are battery powered, the battery is a LiPoly that is tucked inside and recharged. But there’s a lot to be said for common AA and AAA batteries. These are available anywhere around the world, instantly recognizable, and come in various temperature grades and recharability. For user-or-field replacement, or in use of extreme temperatures, they’ve still got a place in product design.
The down-side is that battery cases are often plastic-retained clips that allow dust, humidity, and spilled-diet-coke in, which can cause icky corrosion to the steel or tin terminals.
This Flickr image shows a similar self-corroding affect, but having dampness won’t help!
Challenge’s battery holders are compact, but have 4 screws for secure closure and a built-in gasket that will get you IP65-level sealing. That means fully dust-tight and water-proof to jets of water. Note this doesn’t mean you can dunk it underwater – for that you’d need IP67 or IP68 – these are better for outdoor use or in some industrial settings where there may be liquids flying around.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound.
