Estry ER-GUM1 1.2V Ni-MH battery

The Estry ER-GUM1 is a 1.2V nickel-metal hydride cell rated at 1200mAh and 1.44Wh. It measures 66.78 x 16.7 x 5.96mm and weighs 50.0g. The pack carries ISO9001, RoHS, CE, UN38.3 and MSDS certifications and includes overcharge, over-discharge, over-voltage and short-circuit protection. It suits users who need a direct replacement for the original ER-GUM1 part in compatible devices.

Replaces the original ER-GUM1 cell

This battery is built to the exact specifications of the original ER-GUM1 unit, making it a drop-in substitute when the factory cell no longer holds charge. The upgrade is worth it when runtime has dropped noticeably or the device reports a battery fault. Buyers who need a different voltage, a higher capacity than 1200mAh, or a lithium-based chemistry should look elsewhere because this product matches the original 1.2V Ni-MH specification only.

Check the device model and part number

Confirm that your equipment lists ER-GUM1 as the compatible model or battery part number before ordering. Verify the physical dimensions of 66.78 x 16.7 x 5.96mm fit the battery compartment and that the connector polarity matches. The cell is certified to ISO9001, RoHS, CE, UN38.3 and MSDS standards, so ensure your application accepts these approvals.
