Review on HHR-P104A Panasonic Cordless Phone Battery by Sopheak Kupke

You can get a factory battery for the price difference. Suitable for GIGARANGE series phones. Here's what I found - the shelf life is about 3 years. OEM BAT lasts longer between charges. Here's a curiosity: if you use the factory nimh baht. You will hear a warning tone in your ear before the phone turns off. If the original batteries are new, you may get 3 min warning. You usually won't get a warning with old factory or aftermarket batteries. Bat after-sales service. can be very annoying when they suddenly die and you end the call. I also ran into the OEM bat condition. When you get it, buy directly from Revain, not from the seller in the market. Revain will do the right thing and replace the defective battery. When you receive the battery, charge it immediately within 24 hours. BEFORE USE. Then use your phone intensively and fully discharge the battery before charging. Factory batteries are NiMH, not NiCd and should not have memory effect problems.
