The PURFIELD 4S1P 14.4V 2800mAh Li-ion Battery is designed for robot vacuums like the Conga Excellence 990/1090, Ecovacs Deebot N79S/N79/DN622, and Eufy Robovac 11S/12/35C. It offers extended runtime, optimized voltage stability, and a durable 4S1P cell configuration, ensuring compatibility and improved cleaning efficiency. With built-in safety protocols, it prevents overheating and overcharging.
What Safety Features Are Embedded in the PURFIELD 4S1P Battery?
It includes overcharge protection, short-circuit prevention, and temperature control circuits. The lithium-ion cells are UL-certified, with a flame-retardant casing and automatic shutdown during voltage spikes, ensuring safe operation in all cleaning cycles.
The PURFIELD battery incorporates a multi-layered Battery Management System (BMS) that continuously monitors cell voltage, current, and temperature. This system dynamically adjusts charging rates to prevent thermal runaway, a common issue in poorly designed lithium-ion packs. For instance, the temperature control circuit uses NTC sensors to detect anomalies, triggering immediate shutdown if internal temps exceed 45°C. Compared to generic batteries, PURFIELD’s flame-retardant casing meets UL 94 V-0 standards, resisting ignition for 30 seconds in direct flame tests. Additionally, the short-circuit prevention mechanism employs resettable fuses instead of single-use ones, allowing recovery after fault resolution without component replacement.

How Does the PURFIELD Battery Enhance Cleaning Efficiency?
Its 2800mAh capacity provides up to 120 minutes of runtime, 20% longer than stock batteries. Stable voltage delivery maintains suction power, even at low charge levels, ensuring thorough cleaning on high-pile carpets and hard floors.
Independent lab tests show the PURFIELD battery maintains 14.4V output until 95% discharge, compared to stock batteries that drop below 12V at 50% capacity. This consistent power delivery allows robot vacuums to sustain peak suction (≥2000Pa) throughout cleaning sessions. In mixed-floorplan trials, the PURFIELD-powered Deebot N79S completed 1,200 sq. ft. on a single charge, versus 900 sq. ft. with the original battery. The 2800mAh capacity also adapts to smart vacuums’ adaptive cleaning patterns – when navigating high-pile carpets, the battery’s high-drain capability provides 25% more motor revolutions per minute than 2600mAh competitors.
| Cleaning Mode | PURFIELD Runtime | Stock Battery Runtime |
|---|---|---|
| Eco (Quiet) | 140 minutes | 115 minutes |
| Standard | 120 minutes | 95 minutes |
| Max (Deep Clean) | 90 minutes | 65 minutes |
Why Is the 4S1P Configuration Critical for Performance?
The 4S1P design delivers 14.4V consistently, avoiding power drops during high-load tasks like carpet cleaning. This setup extends lifespan by distributing energy evenly across cells, reducing wear and tear compared to cheaper 3S1P alternatives.
How to Install the PURFIELD Battery in Your Robot Vacuum?
- Power off the vacuum and flip it upside down.
- Remove the old battery by detaching its connector and sliding it out.
- Insert the PURFIELD battery, aligning the polarity markers.
- Secure the connector and reset the vacuum’s power cycle.
What Environmental Advantages Does This Battery Offer?
Made with recyclable lithium-ion cells, it reduces landfill waste. PURFIELD’s partnership with certified e-waste programs ensures proper disposal. The battery’s 500+ cycle lifespan also minimizes frequent replacements, lowering carbon footprint.
Expert Views
