LQM 3.6V 800mAh Rechargeable Battery for Panasonic P-P511 HHR-P402A ER-P511 ER-P507 N4HKGMA0001 Type 24 Cordless Phone Battery

Battery arrived fast and well packaged. Battery seems well constructed and fit perfectly in my Panasonic handset. Have since charged it up, and phone is working great, and handset holds a charged just the same as the OEM battery. In fact I originally bought a replacement OEM battery for this phone and it didn't survive too long.Overall, very pleased with the value for money and quality of this battery, no need to run out to the local RadioShack and pay 5 times as much :)

For me at least, this battery pack definitely didn't work well from the very start. It consistently went dead after about 10 minutes of use even when fully charged. This replacement battery was NiMH and not NiCd like the original, but it still should have worked much better and lasted much longer than it did. It definitely felt like a waste of money.

Was very pleased to find this product for an older phone at a good price. The battery charged fully and seems to be working fine, at less than 1/3 the cost of the local battery store.

Great deal and fast delivery. You can't ask for more from a seller! I'm very satisfied!

Good and efficient customer service...very satisfied.

This rechargeable battery for my Panasonic phone fit perfectly. It charged fully quickly and has been working very well since I first installed it. I would highly recommend this seller as he provides excellent service and sells at a very reasonable price. So far the handset holds a charge very well.

Arrived fast. Works very well. Great value.
