Old cells,the bottom line is that they are still old cells...
I've tried the Spintec Batman
,and it could some how regain some of it ' youth'
. The batman
has this Flex dischage thing that does some thing to the internal structure of the cells.It claims to reduce IR.
Give it a try and your old,new or future cells will thank you for that.I'm getting another Batman
off a friend.Good stuff.
