ABOUT BATTERY not found

before i placed the laptop in storage temporarily, i remove the battery and saw it charged up to 98%.

After 3 months the laptop will not start. i remove the battery and use the charger.

it started but when i replaced the battery back it wasn't recognized. i did the prams/smc etc but no battery. bought one tested it in a similar A1278, charged 100%. Used battery on that laptop only everything ok.

took the battery out and placed in my own, no battery, but i noticed before signing the battery seemed there, signed and the square with an X shows up, no battery detected.

again PRAM/SMC and all the hints i could fine every where but no battery.

i have replaced the magsafe-dc same thing. my research points to the charging circuit which i don't understand how it became defective.

does anybody know a repair shop services for this at a reasonable price?
