Built-in protection guards against overcharge, over-discharge, over-voltage and short circuits. Certified to ISO 9001, RoHS, CE, UN 38.3 and MSDS standards.

Verify model and part number first

Check the device label for one of the listed model codes such as ES-EU20, ERGC50, ES366, ER2171, ES2207P, ER-GS60, W835, EW-1211, ER-GC70 or ES3041. Also confirm the battery part number matches WES7038L2506, WER221L2506, WESSL41L2508, WER217L2509, WESSA40L2508, WES365L2509, EW1211RRB84W, WERGB80L2508 or WER221L2508. Only proceed when both identifiers agree.

Direct swap for depleted original cells

This unit restores runtime to the exact factory specification when the original Ni-MH pack no longer holds charge. The upgrade is worthwhile whenever the device shows reduced operating time or fails to power on, and the model or part number appears in the compatibility list. It is not suitable for devices requiring a different voltage, chemistry or form factor.

Questions about this item

Does the package include a charger or just the ES-EU20 battery cell?

Only the 1.2V 2000mAh Ni-MH cell is supplied; a compatible charger must be obtained separately.

How do I choose between the ES-EU20 and the other listed model numbers?

Match the model printed on your device or the original part number — WES7038L2506, WER221L2506, WESSL41L2508, WER217L2509, WESSA40L2508, WES365L2509, EW1211RRB84W, WERGB80L2508 or WER221L2508 — to the compatibility list.

What does the 2.4Wh rating mean for actual use in my trimmer?

The 2.4Wh capacity determines total energy available; run time depends on the tool's current draw, so a higher-drain device will deplete the cell faster than a lower-drain one.
