Review on Panasonic KX-FPG381 HHR-P511 Battery by Kastar by Kyle Merriman

Genuine Panasonic battery lasts for several long calls. It is best to hang up after a 45-minute call to recharge your batteries. This has nothing to do with the quality of the eForce, in fact they seem to last longer than other regular or non-genuine batteries. Just don't expect the performance of the original. A genuine Panasonic battery can cost upwards of $20 for a phone that is almost 10 years old. you do the math eForce offers the perfect solution at an affordable price.
