Rated 5 out of 5 by from Initial impression is very good. Don't know long term but suspect it will be goodThe standard (removable) battery on my P52s didn't provide sufficient battery life, particularly while traveling (even shorter flights). A secondary issue (with the standard battery) was that, given the standard battery is flush with the bottom of the laptop, the clearance between the bottom of the laptop and the desk is minimal. This results in poor airflow (intake at the bottom) resulting on the computer fan working on high most of the time. This 72Wh battery solved both issues, not only do I have great battery life, but given the protruding design of this new larger battery, it raises the back of the laptop just enough that there is now better airflow, therefore the fan no longer has to work on high most of the time. I've been working at my desk this morning for four hours (and this new battery installed), and I've only heard the fan kick in once (multiple apps, tools, and browsers running). I am very pleased with this purchase for the stated reasons.I hope this helps!

Rated 5 out of 5 by from Great qualityI currently use a T480. The stats below are from a precise nutritional scale:T480 w/o the external battery = 3.3 lbsT480 w/ 24wh battery = 3.59 lbsT480 w/ 72wh battery = 4.03 lbs24wh battery alone = 0.295 lbs72wh battery alone = 0.7319 lbsThe 72wh battery does had a noticeable heft but I only notice it when I am holding it like a dinner plate. I don't feel the weight on my lap or in a backpack. I also no longer need to carry my power adapter since the 2 spare batteries can easily get me through an entire work day, or perhaps even 2! I don't have the 48wh battery, but I believe it is the exact same size but may be slightly lighter than the 72wh battery. The size of the battery is quite acceptable and doesn't bother me at all. It doesn't make the laptop feel or look chunky.Visually the 72wh battery does not look unsightly and remains quite hidden/out of sight. You can really only see the battery if you try to look under it, but from a normal height it remains rather discrete. I actually think the laptop looks better since it appears as if it is elevated/floating above the table. This also creates better airflow and a more desirable typing angle.I haven't done any real tests for battery life, but I can imagine 15+ hours are attainable while doing simple productivity/web browsing. There have been times I have seen crazy estimated readings like 26 hours remaining while doing office work, but I doubt one could actually achieve those kind of run times unless the system was idle. More realistically one could expect 8-13 hours of battery life depending on use.The advantage of getting it from Lenovo is that you will be getting a battery that was manufactured recently. The real problem is it will arrive to your doorstep PAINFULLY SLOW.

Rated 5 out of 5 by from ThinkPad Battery 61++ ExcellentBought this battery to accompany my P52s and it's been worth the money. The battery life is over 8 hours in duration and adds little weight to the console. No regrets buying this product, I'd say its essential and anyone who has the ability to add this to their console should. [This review was collected as part of a promotion.]
