Varta CR2450 Battery

My calculator's display was getting dim and flickering, and this little 3V lithium cell brought it right back to life. The battery sits perfectly in the slot and the voltage holds steady, so I don't expect to swap it out again anytime soon.

My car key fob needed a new battery, and this CR2450 slipped right in without any fiddling. The 3V lithium power has kept the remote working perfectly for weeks now, which is exactly what I wanted.

The 3V lithium hold has been steady in my calculator for two months now, and the display hasn’t dimmed once. I swapped it in during a quick lunch break and haven’t had to think about it since.
