Battery is a little expensive compare to the other regular batteries but it is very strong and last 2 to 3 times longer. Also it holds the charge for weeks at the time with no problem. I was thinking of buying more batteries for spares but I have done several jobs with just one and not had any problems. Got the battery from Amazon in just a couple of days and as always I get great service from them.
