Replacement Battery for Dirt Devil EV3420

This lithium-polymer pack replaces the original battery in Dirt Devil EV3420 vacuums. It delivers 2600mAh capacity at 14.4 volts and measures 132.00 x 37.40 x 20.50 mm. The unit weighs 186g and carries ISO9001, RoHS and CE certification. A fully decoded chip ensures compatibility with the vacuum's electronics.

Steady Runtime on Extended Cleans

The 37.44Wh energy rating supports consistent suction through whole-room sessions rather than brief bursts. Lithium-polymer chemistry maintains voltage under load so power does not sag as the charge depletes. Protection circuits guard against overcharge, over-discharge, over-voltage and short circuits during long runs. Performance stabilises after two or three full charge-discharge cycles.

Slim Profile with Protected Connector

The narrow 20.50 mm thickness lets the pack slide into the EV3420 battery bay without forcing the latch. Shock-absorbing foam in the packaging protects the cells and connector during transit. Installers should verify the part number CM210703-4S1P on the original battery before fitting. Avoid low-quality third-party chargers to preserve cycle life.

Questions about this item

How much heat or noise does the 14.4 V lithium-polymer pack generate during continuous vacuum use?

The battery itself produces no audible noise and only minimal warmth during normal operation; any noticeable heat comes from the vacuum motor and electronics, not the cell pack.

What must I already own for this CM210703-4S1P battery to work in my Dirt Devil EV3420?

You need the Dirt Devil EV3420 vacuum with its original charging dock and power adapter; the battery slots directly into the machine and charges through the dock.

Will this 2600 mAh replacement behave the same as the original battery in an older EV3420 unit?

Yes — it uses a fully decoded chip matching the original specifications, so the vacuum’s fuel gauge, run-time and protection circuits function identically.
