Cheaper than a New Norelco
This battery is almost identical to the original, apart from the labeling. This is not a drop in replacement. You will need a soldering iron to remove the old battery and install this one. This new one does not label the positive or negative terminal, so you will also need a meter to determine which terminal is which. (If you're looking at this battery, you are probably old enough that you've already got a soldering iron and meter but if you don't go ahead and buy some cheap ones from Amazon while you're shopping. You'll find uses for them at least a couple of times a year.) Identifying the terminals and soldering in the new battery is simple. You'll need to charge it overnight. My old Norelco works like new again and I'm happy I took the time to repair it instead of tossing it in the trash.
