🔋 High-Quality Replacement Battery - Rayovac RAY193 for Panasonic HHR-P104, Type 29 Cordless Phones Review

This replacement battery is a game-changer for my old Panasonic phone. Thanks to my knowledge gained in practice, I easily installed the Rayovac Cordless and it's been holding a strong charge for weeks. The fact that it's cordless is a huge plus as I no longer have to worry about being tethered to the wall during calls. The only downside is it took a bit of effort to remove the old battery.

This product is advertised as a replacement for the HHR-P104 3.6V 1000mAh battery shown in the photo above. However, received a 3.6V 850mAh battery which is pictured on the bottom. 850 mAh batteries hold less charge than 1000 mAh batteries and therefore discharge faster. FAILED. item returned.

These are not really Rayovac batteries. The manufacturer is called EBL and they look the same as some replacement batteries I've tried before that were causing corrosion problems in my phone after only a few months. They've gotten generally good reviews, but be aware of what you're getting. I would say genuine Panasonic batteries are Tier 1, Rayovac are Tier 2 and these are Tier 3.
