OKP Replacement Li ion Battery 12.8V/320-2045-1060 For Robot K2, K3, K4, K5

i thought this battery would resolve the issue of the vacuum dying mid cleaning cycle .. i t has not helped at all: the vacuum goes from around 25% to completely dead within seconds leading to a search for the vacuum which is invariably stranded in a corner someplace. sucks

The battery has not been received.

Non è arrivato il pacco!!!

I followed the OKP instructional video and successfully installed the new battery. It recharged promptly and hopefully the robot is good to go for another 4 years.

Never received
