I have found 40y7001 battery in our warehouse and condition of the item is NEW - originally packaged, what can be point that it isn't charge any time. As I found infos in the internet, this product is not selling now. My battery has few yaers for sure...
This battery has few years but I would like to start use it in next 14days - I have to use it
Should I charge it before 1st use to 100% when computer will be turned off?
Next discharge battery by using computer to get 10% load on the battery gauge? Load to 100% ( with computer powered off or on? ), discharge to 10% and load again?
Isn't it nice to find things lying around in a warehouse?
Actually these are still being sold as "new." This is a 4-cell x60/ x61 series (non-Tablet) battery and should have a red dot with "22" number on it: http://support.lenovo.com/en_US/downloa ... D=PD010190
Seems these were manufactured in 2010 and 2011, (not sure if still being manufactured now in 2012), but not such an old battery.
Personally, (whether or not I was planning to use the battery right away), I would charge it fully to 100% with the laptop off
. (Overnight is even better as the battery will fully charge up and then cool down a little before use). Then run the laptop on battery until it goes down to 4.00 Wh (I'm not talking about Remaining Percentage of 4%, but "Remaining Capacity
"= 4 Watt Hours, which should be about 10% in this case). Temporarily change any Sleep settings so the laptop will remain wide awake, ignore 20 minutes remaining, "you should plug in your laptop immediately" or any other such warnings, but just watch it carefully in Lenovo Power Manager and don't let it go any lower than 4.00 Wh Remaining Capacity. Then plug it back in, turn it off or put it to sleep and let it recharge fully to 100%. From that day on, just use it normally, unless you were planning to sell it to someone, in which case you could run it through another Full charge/ discharge cycle to 4.00 Wh. (I have sold dozens of these, and that's what I would do to ensure very accurate battery meter stats and run time estimate). But if just for personal ongoing use, I wouldn't bother with another full cycle unless the battery meter stats/ run time estimate becomes quite inaccurate.
