Direct replacement for Braun groomers

This Estry AAA HR-4U Ni-MH cell matches the original 1.2V 700mAh specification for Braun Series 1 180 and listed MGK, SK and BT models. It fits the same 43.5 x 10.5 x 10.3mm slot and weighs 37.0g, so installation is a straight swap without modification.

700mAh capacity for daily grooming

The 0.84Wh pack delivers enough runtime for several shaving sessions before recharge. Ni-MH chemistry handles frequent top-ups without memory effect, but capacity will fade after a few hundred cycles and the cell cannot supply high-drain loads beyond grooming use.

Upgrades worn original cells

Replaces Braun part numbers AAA HR-4U, HR-4U and 4HGAE-LFU when the factory battery no longer holds charge. The jump is worth it when run-time drops below a single shave or the device shuts off mid-use; it is not a higher-capacity upgrade and will not extend runtime beyond the original design.

Questions about this item

Will this AAA HR-4U battery fit my Braun Series 1 180 trimmer alongside the original charging base?

Yes, it is built to the exact specifications of the original AAA HR-4U cell and is listed as compatible with the Series 1 180 model, so it will work with your existing charging base.

How can I confirm the battery is working correctly after I install it in my Braun MGK7020?

After installation, charge the device fully; the trimmer should run at normal power for its rated usage time, indicating the 700mAh capacity and 1.2V output are performing as intended.

Does the package include a charger or only the single 37.0g Ni-MH cell?

The product is a 1-pack containing only the replacement AAA HR-4U battery measuring 43.5 x 10.5 x 10.3mm; a charger is not included and must be sourced separately.
