Great battery, great price
This has been working in my Panasonic phone for a month and works better than the original. It arrived reasonably fast; not an issue, since the old one was still working - it just didn't last long between charges. Seems to go longer on a charge than the original P-P511 ever did. So far, this is a great bargain; highly recommended!!

Great Battery
I have made purchases from this company and have always gotten quality products from them. This battery has a higher mAh rating than the original battery that came with the phone (a good thing). It came with a charge, but I charged it overnight just to make sure it was full and ready for use. FYI: remove battery before storing your phone for an extended period of time. My original battery corroded on the terminals.

Not like an original...
An original Panasonic battery may handle multiple lengthy conversations. it's best to hang up the handset for recharging after let's say a 45 minute call. Nothing to do with the quality of eForce, in fact these seem to last longer than other generic or aftermarket batteries. Just don't expect the performance of an original. An original Panasonic battery may cost over $20 for an almost 10 year old phone. You do the math. eForce provides a perfect solution at a great price.

Sent wrong item twice!
The battery i ordered was not sent to me but 2 incorrect batteries were. Apparently there's very poor inventory control! i still don't have the right one- they gave me my money back instead of trying to figure out how to send me what I actually ordered.

Excellent performance of the product - i.e. more than expected return of the paid money and quality of the product. Thanks .
I have received this product and was surprised to note the performance of the product compared to the expected quality and what is received for the expected work performance. Thanks to the team who offers such a good quality product. Hope it should beat the market once known to all customers while referring to the review here. Request the customers to atleast try a product for the excellence of the quality product. Thanks, N.C.P.

Perfect OEM Replacement
Perfect replacement battery for original. It was a perfect slip-in replacement and so far has lasted for more than a year.
