Hi, used Doro 5065R +3 for year, found that the battery of the handsets were end of life, called Doro and advised to take the battery from **** Smith. After replaced with DSE (brand name) NiMH rechargeable batteryHR03 1.2V 700mAh 70AAAHC, the charging seems alright, the signal shows strong but it drops out within 10 seconds on in-coming and out-going calls. Any reason for that ? I haven't kept the old battery but I can remember that was 500mAh, DSE told me that's not a problem.Please advise.
