This battery holder links two AA batteries in series, offering approximately 3V for low voltage electronic projects, fitting any standard AA battery. It's designed with a slim profile and an integrated on-off switch.Benefits include enhanced power management with the on-off switch, optimizing energy use without frequent battery removal. Use rechargeable NiMH for a voltage range from 2.7V to 1.8V, or opt for alkalines for 3.2V to 2.2V across their lifespan.The holder's polarity aligns with 2-pin JST cables and Li-Ion/Poly batteries, while the genuine JST connector ensures durability without snagging. Ideal for replacing micro:bit battery packs, it extends battery life significantly, lasting 3 to 5 times longer than AAA batteries. https://elecena.pl/product/29478343/adafruit-2-x-aa-battery-holder-with-on-off-switch-amp-jst-ph-connector 2025-11-03 https://elecena.pl/product/29478343/adafruit-2-x-aa-battery-holder-with-on-off-switch-amp-jst-ph-connector 2025-12-03 https://elecena.pl/product/29478343/adafruit-2-x-aa-battery-holder-with-on-off-switch-amp-jst-ph-connector 2025-12-14 https://elecena.pl/product/29478343/adafruit-2-x-aa-battery-holder-with-on-off-switch-amp-jst-ph-connector 2025-12-20 https://elecena.pl/product/29478343/adafruit-2-x-aa-battery-holder-with-on-off-switch-amp-jst-ph-connector 2026-01-24 https://elecena.pl/product/29478343/adafruit-2-x-aa-battery-holder-with-on-off-switch-amp-jst-ph-connector 2026-01-29 https://elecena.pl/product/29478343/adafruit-2-x-aa-battery-holder-with-on-off-switch-amp-jst-ph-connector 2026-04-08 https://elecena.pl/product/29478343/adafruit-2-x-aa-battery-holder-with-on-off-switch-amp-jst-ph-connector 2026-07-01
