Sorry, there was a problem. Please try again later.Probably best to check their website, but the voltage output you noted is a range, that is 16 v up to/including 19.7. Your previous 18 falls within that range. I don't believe the amperage has any effect on your battery, but I may be mistaken, so best to check, is my recommendation.
Sorry, there was a problem. Please try again later.I would not foresee that this would damage your battery or laptop, but you may want to consult the manufacturer of your laptop/battery for verification, or the User Manual of each.
