ANSMANN CR2450 - CR2450

The 620mAh capacity in this little battery is no joke — my calculator’s been running for weeks without losing power. Perfect fit for my car key fob, too, and it was ready to go right out of the package.

The 620mAh capacity is exactly what my car key fob needed—it's been three months and the signal hasn't weakened once. Installation took seconds and the voltage reads spot-on every time.

Finally found a battery that actually lasts in my car key fob—this CR2450 has been going strong for months now. The 620mAh capacity makes a real difference compared to the cheap ones I used before. Definitely what I needed for my high-drain devices.
