Stops the voltage drop that kills your gear mid-use

Standard rechargeable batteries lose voltage as they drain, which is why your flash, mouse or lock starts glitching before the battery's actually dead. These hold a stable 1.5V output until they're properly empty, then recharge in about an hour over USB-C. Backed by a [X]-day return window.

  • Constant 1.5V output — no voltage droop like standard Ni-MH rechargeables
  • USB-C fast charging, full charge in around 1 hour, no separate charger to lose
  • Delivers 2000+ charge cycles of consistent, reliable power
  • CE, FCC, RoHS, UL, KC certified — built-in overcharge and short-circuit protection
  • Fits standard AA devices: cameras, remotes, mice, keyboards, toys, flashlights

Frequently asked questions

➤ Why would I pay more for these than standard rechargeables?

Standard Ni-MH batteries drop from 1.5V to around 1.2V as they drain, which is why high-drain devices start acting up before the battery is empty. These hold a constant 1.5V output until they're actually depleted.

➤ How long does a full charge take?

About 1 hour via the included USB-C cable — no separate wall charger needed.

➤ What devices are these compatible with?

Any standard AA device — cameras, remotes, mice, keyboards, toys, flashlights and more.

➤ Are these safe to leave on charge?

Yes — they're CE, FCC, RoHS, UL and KC certified with built-in overcharge and short-circuit protection.

➤ How many times can I recharge them?

2000+ charge cycles of consistent, reliable power — years of daily use before performance drops off.

➤ What's the difference between the pack sizes?

Same battery across all packs — the 4-pack includes 1 charger, the 8-pack includes 1 charger, and the 12-pack includes 2 chargers so you can charge two batches at once.

➤ What if it's not the right fit for me?

Backed by a 30-day return window, no questions asked.
