QA & Troubleshooting

Common questions regarding fitment, capacity, and installation.

Is it safe to use a 3400mAh battery if my original was only 2600mAh? +

Yes, it is 100% safe. The voltage (14.4V) is identical to your original battery. The higher 3400mAh capacity simply means the battery stores more energy, allowing your robot to clean for a longer period before needing a recharge.

How much extra runtime will I get with this 3400mAh version? +

You can expect up to 30% more runtime compared to the standard 2600mAh battery. It is an ideal upgrade if you have a larger home, multiple pets, or thick carpets that require more power.

Does it take longer to charge the 3400mAh battery? +

Yes, because it holds more power, it will take slightly longer to charge from 0% to 100%. However, your robot's charging dock will handle this automatically and stop charging when full.

Will it physically fit in the same battery compartment? +

Absolutely. Despite the higher capacity, it is manufactured in the exact same physical dimensions and uses the identical 2/3-pin plug as your original battery. It will fit perfectly.

Is this battery compatible with Eufy RoboVac models? +

Yes! This battery shares the same plug and specs as many Eufy vacuums. It is fully compatible with Eufy RoboVac 11, 11S, 11S Max, 15C, and 30C.
