Title: Brand new LiPo but more than 1 year OLD ----------what to do??? Post by: Ahmad Ilyas on June 02, 2018, 02:09:16 PM I am returning back to the hobby after more than 1 and half year
And while looking at my old stuff , i found 2 LiPos Wolfpack white 2200mAH And Wolfpack White 1500mAH They are older than a year but i never used them (still in the original box) I decided to check them on my voltage checker and they seem to be dead One of them (1500mAH ) , is having one cell alright but other two dead The other one (2200mAH) is totally dead and its puffed I remember it not being puffed when i got it So i have decided to dispose them But how can i do so without hurting anyone or anything or without any fires , These are very well my first dead Lipos Here some pics (https://s33.postimg.cc/vl0s2n64f/20180602_135924.jpg) (https://s33.postimg.cc/6rr81z7of/20180602_135935.jpg) (https://s33.postimg.cc/wajkezyy7/20180602_135938.jpg) (https://s33.postimg.cc/4afgup0mn/20180602_135941.jpg) Title: Re: Brand new LiPo but more than 1 year OLD ----------what to do??? Post by: sanjayrai55 on June 02, 2018, 05:16:41 PM Try to charge them to some extent by using very low current in NiMH mode. Exercise caution, use a LiPO-safe bag if you have one

Post by: Imperial fire on June 04, 2018, 10:50:34 AM EXACTLY dont throw them yet...i have had 2 lipos that puffed ...that i used and then they gradually lost puff for some reason...maybe they got punctured somewhere...they still work fine..
note these were low discharge batteries and were always charged back up very slowly. |
