Question about PK Nextgrid BlackoutBuster B6U2 UPS System
I have no manual for this unit and the back up battery is not working. How do your replace it?
Not hard to replace battery. It is a SLA (sealed lead acid) 12 volt 7AmpHour. Runs $20 to $30. To remove just unscrew 4 screws on the back and 4 screws on the side. The front panel snaps out from the bottom use a flat blade to push up the tab from the opening on the face plate. The unit will operate without the battery just no backup.

I had the same problem until I found this website with the information on how to replaced the battery on the Blackout Buster. This is a step by step on replacing the battery so far it worked out for me. Here goes the website: http://www.passwordmethod.com/content/view/134/43/ Let me know if it works out for you.

This is for the Blackout Buster by PK or PowerKinetics B6U model (as shown on the bottom of the unit). I have no manual, but I have always gotten the correct battery from:
You might want to visually look at your battery terminals to be sure and select the correct terminal config. Or, at least give them the s/n and model number on the bottom. IME, this is the BEST UPS I have ever had. My Father and I have each had one for almost 10 years. Now, if someone could point me to a place that sells the communication cable for it, I'd appreciate it.

Best to get the exact size replacement battery, but if it's not available and provided you have experience with electrical wiring and can make good connections, you could use any spare 12V battery of sufficient capacity and wire it externally to the wires that the battery normally connects to.
The wire used should be thick enough to carry high current, 10AWG. Use a 30A fuse at the battery to protect against accidental shorting.
If the battery is larger capacity than the original, it'll allow for a longer run time than the original.
Also, if you find the unit doesn't turn on or off when you push the button, check the plastic lever under the front cover that translates the up/down motion to the sideways push needed for the on/off switch.
The front plate is easily removed with a flat blade screwdriver as mentioned above, push straight up from the bottom to release the latching tab, and the front cover pops off. Unhook it from the top to remove the front plate.
You might find the lever fractured, so pushing the button doesn't do anything. I epoxied mine back as a fix. Probably would be good not to push too hard on the button to avoid this from happening in the first place.
