- Easy installation with just a screwdriver, no technical skills required.
- Multiple safety protections built in for reliable, safe charging and use.
- Direct compatibility with Aiper Seagull SE, no modifications needed.
- Low self-discharge keeps the battery ready even after periods of non-use.

The YCFSERMYO 4000mAh replacement battery is a dedicated power solution for the Aiper Seagull SE cordless pool vacuum. It is designed for homeowners who want to revive their pool cleaner's original performance without buying a new unit. This battery is a direct drop-in replacement, making it a convenient and cost-effective option.
Standout features include a high 4000mAh capacity that allows the Seagull SE to clean larger pool areas in a single charge, reducing downtime. The battery uses high-density lithium cells that provide a steady 10.8V output, avoiding the power drops that can leave debris behind. In real-world use, this translates to consistent suction and thorough cleaning from start to finish.
The build quality is solid, with a blue casing that matches the original battery's dimensions and connector. Installation is truly plug-and-play: remove the old battery, slide in the new one, and tighten a couple of screws. No cutting, soldering, or adapters are needed. The battery also includes multiple safety protections (overcharge, over-discharge, etc.) for added peace of mind.
One potential drawback is that this battery is strictly compatible with the Aiper Seagull SE only, so it won't work with other models or brands. Additionally, there are no customer reviews yet, which means long-term durability is not confirmed. However, the specifications and certifications suggest a well-made product.
Overall, if you own an Aiper Seagull SE and need a replacement battery that restores full cleaning time and is easy to install, the YCFSERMYO 4000mAh is a strong choice. It offers a good balance of capacity, safety, and value for the price.
Buying Guide
Compatibility with Your Pool Cleaner Model
Before buying a replacement battery, you must confirm it fits your exact pool cleaner model. The MPF Products battery is designed for Water Tech Pool Blaster Max and MTC 3937 Megatech, but it is not compatible with the Pool Blaster Max CG commercial grade. The GOXX battery is exclusively for the Aiper Scuba SE, while the YCFSERMYO battery works only with the Aiper Seagull SE. Always double-check your model number before ordering.

Battery Capacity and Runtime
Capacity is measured in milliampere-hours (mAh). Higher mAh means longer cleaning time per charge. The MPF Products battery offers 3000mAh, which is a solid upgrade from many original batteries. GOXX also provides 3000mAh, but it is a lithium-ion upgrade from the standard 2600mAh, giving 15% more runtime. The YCFSERMYO battery goes even further with 4000mAh, allowing you to cover larger pool areas without recharging.
For many users, a 3000mAh battery is sufficient for average-sized pools. If you have a larger pool or want extra cleaning flexibility, the 4000mAh option is a smart choice.
Safety and Certifications
Safety is critical when dealing with rechargeable batteries. All three products include built-in protection against overcharge, over-discharge, overvoltage, overcurrent, and overheating. The GOXX and YCFSERMYO batteries are RoHS certified, ensuring they meet strict environmental and safety standards. The MPF Products battery comes with a 1-year replacement warranty, giving you peace of mind.
When you buy aftermarket, always look for these safety features. They prevent damage to your pool cleaner and reduce the risk of battery failure.
Ease of Installation
None of these batteries require special tools or wiring skills. Each is designed as a direct replacement that fits the original battery compartment. The GOXX and YCFSERMYO batteries are plug-and-play; you only need a screwdriver to open the compartment. The MPF Products battery is also a drop-in replacement for Water Tech models. Installation takes just a few minutes, and you can get your pool cleaner back to work immediately.

Both batteries are easy to install and will extend the life of your pool cleaner significantly.
Frequently Asked Questions
Can I use an aftermarket battery in my Water Tech pool cleaner?
Yes, as long as the battery is designed for your specific model. The MPF Products battery is compatible with Pool Blaster Max and MTC 3937 Megatech, but not with the commercial grade CG version. Always verify your model number before purchasing.
How long does a replacement battery last for an Aiper pool cleaner?
Runtime depends on battery capacity. The GOXX 3000mAh battery gives about 15% more runtime than the original 2600mAh, covering larger pools. The YCFSERMYO 4000mAh battery offers even longer cleaning sessions. With proper care, these lithium-ion batteries last for many charge cycles.
Are aftermarket pool cleaner batteries safe?
Yes, if they include built-in protection circuits. All three batteries reviewed have overcharge, over-discharge, and short-circuit protection. The GOXX and YCFSERMYO models are also RoHS certified. Always buy from reputable brands to ensure safety.
Will using a higher capacity battery damage my pool cleaner?
No, as long as the voltage matches the original. The GOXX and YCFSERMYO batteries maintain the same 10.8V as the original Aiper batteries. Higher mAh simply means longer runtime and does not affect the cleaner’s electronics. You can safely upgrade to a higher capacity battery.
