I buy second-hand MBP 13inch in shop, they given 45watts charger, that time I don't know much details about of MBP,
last week I replace new battery my MBP 13" ,
I check apple site they mention 60watts charger ,
if I still using 45watts charge , they any chance to damage my new battery ?????
and I using windows 10 on my MBP 13" also, windows can drain power faster & heat up MBP more,
so that time input voltage 45w no enough means they any chance have SMC can stop my battery charging,
because it happened after I reset SMC only I can able to charge again,
can u check the link for me
