my computer I bought maybe 3 years ago and for school, I got a bigger battery now after 2 months of the new battery it charges then does not charge constantly after 70% I have tried the ACPI battery complaint that only worked for a week and now does not work. in 12 hours once it hits 70% it only gains 1% which is not right. but this exact battery works fine in our other laptop which is running windows 10 mine is windows 7. I have tried different chargers and nothing every method google provides did not work.
