CELLONIC, Battery for Vacuum cleaner compatible with ECOVACS Deebot Ozmo 920, S09-LI-148-3200, 930 (14.4V, 3400mAh)

My o mo 905 has a 2600 battery s11-li-144-2600 and this 3400mah was a leap of faith. In theory the capacity wouldn't be a worry but if you have an 'intelligent' battery this could be a challenge. Not on this case, the bigger capacity increased the performance. The old battery wasn't cleaning this 21m2 area anymore and you can see now it's half of the battery y in full power suction mode. So it will clean 40m2 easily.

Finally got a battery that works excellent performance

My Device was having trouble getting through the day on a single charge. The battery, which had been a dependable, was now requiring continuous charing. The battery is a simple replacement. I can now use my device without worrying about the battery running out. If you feel like your device needs a little extra juice, this replacement battery could be what it needs. Everything required for a complete and safe replacement was included in the kit too. No extra tools required. Fully recommend to revive your old device.

Good quality replacement battery. Very reasonably priced and it works just the same as the original.
