How to Change UPS Batteries

Do you have a Uninterruptible Power Supply (UPS) that needs new batteries? Well here is how I changed the batteries in my Tripplite Smart PRO UPS Model Smart700SER.

Lookup the model number and find the proper replacement batteries

Be sure to switch the UPS off and unplug it from the wall outlet.

Here is the battery panel.

I removed the screws and open the panel.

I removed the batteries, but I also kept track on how the power wires go. See the red positive connection on the top left, and the black negative on the bottom right. Those go to the UPS unit.

Here is the new batteries nicely packed.

I now compare them to the old batteries and make sure its a match.

I am making a handle to remove the batteries just like the old one had.

I wrap thick duct tape around both batteries.

Then I tape it to itself and make a strong handle.

I transfered the wire to the new battery. Now the new battery matches the old one.

Now to slide the battery into the UPS, being sure to connect the power wires correctly.

I have now connected the negative power wire.

The battery is now inside, but the tape handle is in the way.

I taped the tape handle up and out of the way.

Having a nice handle there will really be nice next time I need to change the batteries in my UPS.

Now to plug it in and flip the rear switch on.

This UPS also has a switch in the front that I need to hold for a second to power on the UPS.

Everything is back and good! DONE!

The last thing is leaving it charging for a while, then power on all the devices again (Computers, Servers, etc)
