It appears that these two batteries are small enough to fit in the DSO Quad’s opening #LP383454 and LP383560. I see this note on the below web page “# means the battery is UL certified and has ready mold.” I don’t know what the ready mold thing means. They have slightly lower mAh ratings, however mine ballooned on me so I now has a 0 mAh battery. I’ve inquired with eemb to see how I obtain the #LP383454 which has 700mAh and fits in the opening.
