Estry 12.0V 1500mAh Ni-MH Replacement Battery

The Estry 900273733 is a 12.0V 1500mAh nickel-metal hydride battery built to match the original specifications for compatible AEG devices. It serves owners of models 900273733, 900273722, AG3003, AG3001, AG3002, 900273735 and 900273710 who need a direct replacement power source.

Thermals Noise and Power Draw

Ni-MH chemistry delivers a stable 18.0Wh output with built-in protection against overcharge, over-discharge, over-voltage and short circuits. The pack operates without active cooling, so it runs silently and adds no measurable thermal load to the host device during normal use.

Bundled Accessories and Software

No accessories, cables or software are included with this battery. Buyers who need a charger, mounting hardware or firmware tools must source those separately. The unit is certified to ISO9001, RoHS, CE, UN38.3 and MSDS standards for safety and environmental compliance.

Questions about this item

How do I install the 12.0V 1500mAh battery in my AEG tool, and what step is often missed?

Align the pack's 90.4 x 76.5 x 53.7 mm dimensions with the tool's battery bay, slide it in until the latch clicks, then fully charge the 18.0 Wh Ni-MH cells before first use — skipping the initial charge is the common mistake.

What maintenance or replacement will the Estry 900273733 battery need over time?

The Ni-MH chemistry self-discharges during storage; recharge every three months to prevent deep discharge, and expect the 1500 mAh capacity to fade after roughly 500 cycles, at which point a replacement pack is required.

What limit appears first when the 12.0V pack runs under sustained load?

Internal resistance of the Ni-MH cells causes voltage sag once the pack temperature rises, so the 12.0 V output drops below the tool's minimum operating threshold before the 18.0 Wh capacity is fully depleted.
