My radio was an Eton Microlink FR160 . Looking at reviews from previous buyers , it IS necessary to change the polarity of the wiring . Simple to do . Mark connector , then depress pin tab thru side of plastic connector , and gently remove wire and pin from connector . When both are out , reverse position of wires , then gently slide pin into connector until pin tab locks into place . **Q: Will this fit a c crane observer radio?** A: Spec on the battery: Type: Ni-MH Cell: 2/3 AA ( times 3) Voltage: 3.6 V Current rating: 800 mAh Battery Dimension: 1 3/4 in x 1 1/4 in x 9/16 in. Visual image of battery and specs are in the radio's user manual. Not sure about dimension. **Q: will it work with microlink FR160** A: The battery fits and works on an Eton FR-300 radio. Not familiar with Eton FR-160. **Q: What are the dimensions of the battery pack? Fit Grundig emergency radio?** A: Width 1.671, height 1.135, depth 0.568 inches. Height value omits the leads and connector. Battery pack marked Ni-MH 2/3AA600mAH 3.6V. Battery pack fit my Kaito KA500 emergency radio perfectly and the wiring was correct (ref. some other comments). Don't have a Grundig. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Works well *by L***L on February 14, 2026* Battery works well in my Grundig emergency radio ### ⭐⭐⭐⭐⭐ Well Made *by A***R on May 3, 2025* I bought one several years ago as a replacement for an emergency radio.
