With this purchase battery, it's not likely to change.
easy purchase:
1- I order,
2-qq days later (very quickly) I receive a small package (good packaging)
3 already charged battery but on principle I remade a full charge.
4-is nickel in my viseuse black and decker.
I was torn between buying a new viseuse, well, frankly I do not regret.
power is much higher and allows a much higher speed.
Forward, I hope it will not damage the engine.
for now it is plug and play and it's perfect !!
I highly recommend,
a purchase without worries!
