Been waiting for an opportunity to pick up this item to check all my Makita LXT batteries. Easy to use and very intuitive. Warning: it's pricey if you don't really care too much about the longevity of your batteries. I think it's an essential item for contractors with a large number of Makita tools as batteries are so expensive these days, so being able to keep them working longer saves cash
Packaged in it's own case and fit in my battery packouts. Easy to use and understand the screens.
If you are a Makita tool owner and you have invested a lot then you need this battery checker. I have over 15 Makita batteries and this has helped know which ones I needed to retire and recycle. Also I know the health of batteries that I purchase from other Makita users. Worth every penny.
