### ⭐⭐⭐⭐⭐ Perfect for ATT hotspot
*by G***S on December 14, 2025*

What a surprise that ATT hotspot battery couldn’t be purchased at my local ATT store. But, Amazon came to rescue and am now up & running Excellent

### ⭐⭐⭐⭐⭐ Great price
*by U***R on March 1, 2025*

I was so surprised at the price. Considering the price of the wifi device, I expected the replacement battery to be much higher. Pleasantly surprised!

### ⭐⭐⭐⭐⭐ It works, new and not reconditioned
*by N***S on September 10, 2024*

The battery's arrival was timely. It is an exact replacement for the original battery, which had become swollen. After several days, the battery is working splendidly. Update after 1 month. Battery routinely overheats, causing hotspot to go off-line often until battery cools. Far less pleased.
