Question about Hitachi 18V Lithium Ion Cordless Hammer Drill DV18DL

2 Answers

Drill stops unexpectedly

I bought this drill at Lowes on sale. Now I know why it was on sale. I have a 7 yr old Ryobi set which has served me well but it was time for an upgrade. After about 20 mins of use the drill just stopped. I was very disappointed. My old Ryobi could go for much longer. I thought the Lithium batteries were so much better. Not sure if the drill is defective, the batteries are defective, or the batteries just drain quickly. I have a hard time believing that the batteries drain that quickly. If so, I'm very, very disappointed.

    some more details about the problem. I charged the batteries for 24 hours as recommended in the manual. when the drill stopped worked, I waited a few seconds and it magically worked again, then cut out again. Is this a defective battery or a defective drill?

I have had 2 of the same drills with the exact same problem. The first one worked for about 10 minutes the first time I used it before it started cutting out. I took it back to Lowes and got bought a new one. The new drill does exactly the same thing. If I charge the battery it will work for a few minutes and then starts working only intermittently. I stuck in the second battery and get the same thing. I was just using it to take some screws out so I wasn't even puting a load on it and only got maybe 10 minutes before it started cutting out.
I would highly recommend staying away from the Hitachi Lithium drills. I will certainly never buy another one.

14.4 volt cordless drill --- yelloow and green light on lo0nger than 15 minutes, cannot find user manual.

The battery will no longer take a charge. Time for a new one. I had 2 like this in the last month. The batteries where 5 years old and been charge for over 800 cycles each. Age and cycles will wear them out.

If the tools is still good jsut get new batteries. But check the prices. I just bought a new drill and saw set for $90 and 2 new batteries were $60. I got a new set, since the drill was 8 years old and worn out.

My Ryobi 7.2v drill stopped working (8 yrs old). I bought a new battery, not including the charger cable, and it charges just a tiny bit. Should I replace the cable or buy a new drill?

You will find that a higher voltage drill has a lot more power--especially if the battery is a Lithium type instead of Ni Cad type. Each charge runs longer and doesn't tend to lose charge by itself as much. Good luck!

Ryobi has their own website to go on for any part that you need. You need to know all info on the drill like yr., make ,mdl. etc... I purchased a switch for my ryobi table saw and they shipped it quick and the parts are inexpensive.

Very little juice in freshly charged batteries

have you tried the batterys in any other tool?

you would also need to check the voltage of the batterys they should be at least 18 volts (19 prefered)

then if the batterys do not show charged you would need to make sure the battery charger is putting out voltage.

After that contact your closest Ryobi service center we would check that for free to let you know what you need, I am sure you local place would do the same.
