Hi Graphixo .


Greetings. 

 

Do you have the machine number of your Y50-70, so we can get actual part number  

(keep your serial number confidential)

Check on this link to get the machine number and parts listing . 

Then you may compare it to what I was able to get based on the Maintainance Manual for your pc model. 

 

Part listings: ( Item14Page91) 

 

Part number 121500250
Y50 SP/A L13M4P02 7.4V54Wh 4cell bty (Y50-70/Y50-80/Y50-70 Touch/Y50-80 Touch)

(ex. part and price on ebay

 

Part number 121500251
Y50 SN L13N4P01 7.6V54Wh 4cell bty (Y50-70/Y50-80/Y50-70Touch/Y50-80 Touch)

(ex. part and price / Ebay

 

Removing battery steps( Page 36)

Battery type : Lithium-ion polymer 4-cell (54Wh) battery 
Battery life: FHD: up to 5hrs; UHD: up to 4hrs

Try to avoid getting batteries from unknown distributors to avoid low quality performance. 

You may call in to check for availability and pricing by calling Lenovo Support.

 

Hope this helped you in your decision.

 

 

Regards,

Re: Lenovo y50 70 Battery Replacement

Hi Graphixo ,

 

Thanks for the immediate reply . 

 

So far we both have a match for the recommended battery part number 121500250 .

 

I search on most available Machine number:

Using machine number ( 59413538 , 59414471 , 59414497 , 59414501 , 59414504 , 59415242 ,59416729 and 59414466 )  .

All of them are using  BATTERY part 121500250 (Y50 SP/A L13M4P02 7.4V54WH 4CELL BTY 

Similar to the Part listings: ( Item14Page91)  

 

So that we can be 100% sure .

Can you click on this to check the machine number of your Y50 70 using your Serial number 

(we just need the machine number , keep your Serial Number confidential)

 

I feel that   BATTERY part 121500250  is 90%  recommended. 

But if you got that part number directly from the parts look up page , then that would be it . 

You may order it directly or compare price from other resellers.

 

Check back with us as soon as you can. 

Hope that I was able to help you on this.

 

 

Regards,

Re: Lenovo y50 70 Battery Replacement

Hi 

 

 

You may call in Lenovo to check for availability

Would Kashmir be in Pakistan ? 

Sorry that Lenovo Pakistan may not have the part available since they don't have this model sold within Pakistan.

 

 

If your sister would be coming back home soon then maybe she can just order it for you. 

Maybe Amazon Pakistan or ebay have it. 

 

You may mark our post as an accepted solution to help other members in the community with the same inquiry. 

 

 

Cheers,

Re: Lenovo y50 70 Battery Replacement

THERE IS AN OPTION CALLED CONSERVATION MODE IN LENOVO SETTINGS

*******TURN****IT*****ON******

IT WILL ISOLATE BATTERY WHEN IT IS CHARGES AT 60%

DON'T TAKE SUPPLY FROM BATTERY IF YOU USE LAPTOP FOR LONG TIME

TURN THIS OPTION ON AND PLUG THE LAPTOP ...... NOW YOU CAN USE LAPTOP AS LONG AS YOU WANT WITHOUT WORRYING ABOUT THE BATTERY LIFE

CONTINUOUS CHARGE-DISCHARGE CYCLES REDUCES BATTERY LIFE.....
