Replacement pack for AA x 2 devices

This Estry battery pack replaces the original power source in equipment that uses two AA cells wired for 2.4V output. It is built to the same electrical specification as the factory cell and carries ISO9001, RoHS, CE, UN38.3 and MSDS certification for safety and compliance.

Direct drop-in for worn Ni-MH cells

The pack restores runtime when the original nickel-metal-hydride cells no longer hold a useful charge. Swapping it in is worthwhile when the device still functions but operating time has dropped noticeably below the original 2000mAh rating.

4.8Wh capacity for intermittent loads

At 4.8Wh the pack comfortably powers low-drain electronics such as remote controls, sensors or backup memory circuits for extended periods. It will run out quickly if used in high-current applications like motor-driven toys or bright LED lighting.

Questions about this item

What space does the 52.0 x 28.8 x 14.6 mm pack need inside the device?

The pack measures 52.0 mm long, 28.8 mm wide and 14.6 mm thick, so the battery compartment must provide at least that much internal clearance.

How do I install the 2.4 V Ni-MH pack and what step is often missed?

Insert the pack with the correct polarity, then fully charge it before first use; skipping the initial full charge is the common mistake.

When will the 2000 mAh pack need replacement and what care extends its life?

Expect roughly one year of service; avoid overcharge, deep discharge and short circuits to reach the rated cycle life.
