Questions & Answers

  • Q:

    "Why did you choose this product?"

    • A:

      I chose this product because I have Uniden phones that I like and do not want to replace but the batteries finally wore out. I tried a similar batter with less mAh and they quickly died or did not work well to begin with. I purchased one of these at Staples and it works great. Your prices are much much better so I'm ordering the remaining 3 from Overstock.

    • A:

      needed new batteries

    • A:

      I bought 2 of them years ago and need more of them to replace batteries in my other phones. The higher current rating allows me to leave them out of the chargers for a longer period of time.

    • A:

      lowest price I found

    • A:

      I need new cordless batteries and have always been pleased with my purchases from you. Your price is also much lower than Staples. Thanks!

    • A:

      Fits the phone; been trying to find the battery.

      Hello sandyliu10, The options are for the number of battery two-packs you want to buy. If you buy one, you get two batteries, and so on. We hope this helps you. Thanks for shopping with us.

  • Q:

    "This is pack of 2, so we can purchase the number of packs. Then what is the options means? Battery (2 pk) means sell in 2 packs for 4 pcs? The order quantity will multiply it?"
