NEW PRODUCT – 3 x AAA Battery Holder with On/Off Switch and 2-Pin JST
NEW PRODUCT – 3 x AAA Battery Holder with On/Off Switch and 2-Pin JST. This battery holder connects 3 AAA batteries together in series for powering all kinds of projects. We spec’d these out because the box is slim, and 3 AAA’s add up to about 3.3-4.5V, a very similar range to Lithium Ion/polymer (Li-Ion) batteries and have an on-off switch. That makes them ideal for use with 3.3V projects that have a 2-pin JST connector meant for one of our Li-Ion/Poly batteries. (Of course, you can’t recharge them like Li-Ion/Polys, so don’t try to plug this into one of our Li-Ion/Poly charger boards!)
Fits any standard AAA battery. When using rechargeable NiMH the output voltage will range from about 3.7V with charged batteries to 2.7V at the end of life with a nominal voltage of 3.6V. When using alkalines, the output will range from 4.6V with new batteries to 3.3V at the end of life with a nominal voltage of about 4.5V
The polarity matches that of our 2-pin JST cable and Li-Ion/Poly batteries. Uses a genuine JST connector so it wont ‘catch and tear’ in JST connectors.
Box Dimensions: 2.5″ x 1.45″ x 0.62″
Cable: 6″ long, terminated with a genuine JST-PH 2 pin connector
We are angry, frustrated, and in pain because of the violence and murder of Black people by the police because of racism. We are in the fight AGAINST RACISM. George Floyd was murdered, his life stolen. The Adafruit teams have specific actions we’ve done, are doing, and will do together as a company and culture. We are asking the Adafruit community to get involved and share what you are doing. The Adafruit teams will not settle for a hash tag, a Tweet, or an icon change. We will work on real change, and that requires real action and real work together. That is what we will do each day, each month, each year – we will hold ourselves accountable and publish our collective efforts, partnerships, activism, donations, openly and publicly. Our blog and social media platforms will be utilized in actionable ways. Join us and the anti-racist efforts working to end police brutality, reform the criminal justice system, and dismantle the many other forms of systemic racism at work in this country, read more @ adafruit.com/blacklivesmatter

Any thoughts on waterproofing this? I’ve got a 3xAAA device with a bad battery pack that I need to replace, but it’s meant to be submerged.
Sparr, thanks for the suggestion. We will have some weatherproof battery holders in the shop soon (no ETA, they’re still in manufacture) but they wont necessarily be rated for submersion (that’s really tough to do with a power source) – they’re meant for use outdoors but they -might- work for a quick dunk
