TREE.NB18V Longer Battery Life Battery Replacement for Hitachi BCL1815, BCL1830, BCL1840, 327730, 327731, 326240, 326241

Been using it on my older model Hitachi drill and circular saw. Charges fine and works fine. No issues.

Although the first battery we received only lasted a single charge before shorting out internally, the company did replace it, fast and free, and the second battery is now working great. We have used it multiple times now with no issues. A good buy.

I was very hesitant to buy one of these after market batteries, because of numerous reviews stating that OEM chargers wouldn't charge these batteries. Luckily, the battery I received charges very well using my OEM charger. ( Note: At first, my OEM charger registered this battery as broken. However, after I pulled the battery and reinserted it back into my charger, it started charging properly. I never had this problem again.)So far this battery is performing very well.

This battery is horrible the first time I used it I thought it was unusual that the charge only lasted about 20 minutes I've had this battery five weeks I've used it for a total of maybe three or four times and the battery is completely shot it's dead in fact something happened when it failed and it destroyed my battery charger do not order this item

Used one time, and will not charge with Hitachi OEM charger.

Worked great for three months, then died!

Works great for my husband's drill

So from what I have read online, it's touch n go if it will work. Item came fully charged and had a lot of juice. No I'm playing it Lasted about 15 min total and it didn't work again. So I go 1 use out of it. Value was good longevity horrible.
