Tempted to buy an off brand. Walmart had good $.

Was tempting to buy an off brand but Walmart had this OEM battery at good price. It is the exact right product, no sense, regarding emergency backup, taking a chance with an off brand copy. Fit and worked right away.

As described, simple to install

I needed to replace my battery backup so I ordered online. Arrived as expected, found YouTube video on how to change it...simple and easy.

Exactly the part I needed. Good quality!

After 10 years the battery backup needed replacing. Ordered the new battery and fit perfectly. On to the next 10 years.
