This worked with Midland BATT5R .. A battery pack with 3 unknown Ni-MH inside !I simply connected the output terminals to a similar 6V source and then the pack would recharge - Interesting - there are 2 sets of pickups / contact on the pack - 2 are used for charging within the radio and 2 are used for output - Checking with a volt meter I was getting a reading from the output terminals 6.3 Volts BUT there was no reading across the charging terminals 0.0 V !! . I thinks Stephen4872 explanation about metalic dendrite crystal might explain a lott- I thought these batteries were complete gone ! -and was actually look on Ebay & Amazon for replacements when I happened across this site -Thank you Paul1212 - you saved the day ..
