Lowe's sells a replacement battery that works in both QX computers as a replacement for a dead original. Lowe's Item #1233298 & Model #EBPLC-39-2 and is $10.95 at present. You need to desolder the leads from the original and solder them onto the new battery. Trim the leads on the new battery to first. Observe polarity! I used two new tie wraps to hold the new battery in place.
