| Brand | EGR |
|---|---|
| Color | Gray |
| Battery model | DC31 |
| Capacity | 6200mAh |
| Runtime (normal mode) | Up to 28 minutes |
| Runtime (high performance) | Up to 12 minutes |
| Best for | Owners of a compatible Type A Dyson DC31, DC34, DC35 or DC44 model needing a replacement battery |
Product Overview
EGR builds this as a direct replacement battery rather than a universal fit, aimed at owners of specific Dyson handheld vacuum models whose original battery has worn down. The listing is explicit about a Type A versus Type B distinction: it fits DC31, DC34, DC35 and DC44 Type A models and related part numbers, but does not fit DC34 Animal or DC44 MK2, labeled Type B.
Given this split, EGR directly advises checking the specific machine's part number before purchasing rather than assuming compatibility from the model name alone.
Score Breakdown
This verdict is based on the manufacturer's stated specifications, the current Amazon listing and its product images, the confirmed materials and design, real buyer ratings, and our research into the product category. Scores are consistent editorial judgments, not laboratory measurements, and we did not receive a paid sample.
Key Features
Up to 28 minutes normal mode, 12 minutes high performance.
Tested under strict quality standards.
Pressure, temperature and current safeguards.
Helps prevent the vacuum from falling when leaned against a wall.
Ships alongside the replacement battery.
Fits Type A DC31/DC34/DC35/DC44, not Type B.
Design and Build Quality
The battery measures about 5 inches long, 6 inches wide and 4 inches tall, weighing about 0.4 pounds, finished in gray. A non-slip strip is built onto the battery, which EGR states helps keep the vacuum from sliding or falling when leaned against a wall.
Safety certification is a specific stated point: each battery is tested under UL and CE standards and is RoHS certified, with built-in protection against pressure, temperature and current issues rather than relying on basic circuitry alone.
Performance in Everyday Use
Capacity is rated at 6200mAh, which EGR states supports up to 28 minutes of runtime in normal mode and up to 12 minutes in high performance mode, giving two specific, checkable runtime figures depending on how the vacuum is used.
EGR frames this capacity and the certified safety protections together as delivering stronger suction and a longer lifespan than other replacement battery brands, positioning the product as a direct upgrade path rather than just a basic replacement.
