Questions about this item

What voltage and capacity does the Estry T12 Ni-MH pack deliver, and what does that limit in use?

The pack supplies 12.0 V and 3300 mAh (39.6 Wh), so runtime is capped at that energy level for any device drawing power from it.

What are the exact dimensions and weight I need to clear for the T12 battery to fit?

It measures 124.5 × 61.0 × 61.9 mm and weighs 895.0 g; verify your device’s battery bay against these figures before ordering.

How is the Estry T12 installed, and which step do buyers often miss?

Slide the pack into the compartment, align the BPS12/BPS12S/BPS12C connector, and latch it securely; the step most often missed is confirming the part number matches your original.
