Purchased this battery for $36 as a replacement battery for my HP notebook computer, G60 series. The battery fits perfectly, and charged up well. I ran the calibration for the battery after charging the battery a couple of times. The battery seems to hold a great charge, seemingly lasting as long as the original battery did when the computer was first purchased, providing at least 2 hours of use with moderate use when using the HP recommendation power settings.
I don't know that there was an issue, however, about a week after installing the battery, my HP Total Care Advisor indicated problems with the battery. I recalibrated, and all has been good, and have checked the battery several times since then.
I noticed the battery dropped to $29 about a week or so after I bought it, which makes it an even better deal. I was even tempted to purchase an additional battery for that price. If this battery is still going strong in a month, and the price is below $30, I will more than likely do this, as even at less than $70 for two batteries, it is a steal, as I expected to pay $50 - $75 for a replacement battery when my original started going bad.
As a prime member, my 2-day shipping came on schedule, and the battery was well packaged.
