Replacement Battery for Hovo 510 Series and bObi Robotic Vacuums. 14.4V, 2200mAH, NIMH Rechargeable Battery.

Works better than original due to a bigger mAh capacity than the original battery. I've used it for several weeks and it seems to be doing well. Saved me from having to buy a new unit.

Bought this to replace a dead battery in my bobsweep robot pet vaccum. Was perfect fit and works great. The charge also lasts longer than the told battery.

This fits in the bobsweep pet version and the charging works surprisingly well considering it's a different chemical makeup than the lithium battery from the factory. The cable too connect the battery was longer than the factory battery but with enough wiggle and it'll eventually fit. Saved be hundreds of dollars buying a new pet vacuum.

Lasted 5 months. Worked fine until it didn’t.

This fits in my Bobi Classic robotic vacuum. I have run it 3 times so far on this new battery and am getting 2.5 times the run time (100 minutes+ vs. 40 minutes) of the old original battery, even when the original was new!A great upgrade at the same price that Bobi charges for their lesser power 1700 mah batteries. Upgrading from 1700mah to 2200mah shouldn't change run time that much...but I am very pleased.Hopefully this lasts for a year or longer of almost daily use.

Worked right out of the box. I needed it as a replacement battery for my Bobi vacuum.. works as it should.

Update: they have agreed to send me another battery. Hopefully this one last longer because it did allow bobi to run longer.Well this battery worked great for about s month and then just stopped working. My Bobi now goes off the dock and then has to go right back on the charger. This battery is horrible. the old one last longer than this one now.

I ordered the battery but the connector is not the same as the one I have, still a great battery
