Hi-Capacity NiCad Powertool Battery for Ryobi HP1441MK2, FL1400, R10521 (1400671)

Comment: This item looks identical the original battery (except it has orange release tabs instead of Grey). That being said the fit is a little different. The battery releases easily from the cordless drill but is very difficult to release from the flashlight. I bought two of these batteries and can't get either of them to release easily. To get it out I have to push in the tabs and twist and pull the battery. Not a big deal. Overall the initial charge worked great. It remains to be seen if the battery will sustain its charges but so far so good.

Comment: I bought two of these for my Ryobi drill as direct replacements for the original Ryobi 1400671 batteries. The new batteries have a higher current amp-hour rating than the originals and work and fit perfectly. They are a great replacement and much cheaper than getting them from Ryobi.
