Hitachi Drills - Recent Questions, Troubleshooting & Support
Two brand new Hitachi BSL1815X
These batteries have big problems that Hitachi doesn't address very well. Unlike NiCad batteries, Lith-Ion ones must be periodically used and recharged to retain their battery functions, i.e. if they have been sitting on the shelf at a store for an extended period of time, chances are they will be dead when bought and will not accept a charge. If they go dead i.e. no little red light on the charger when you plug the battery unit in...it's basically junk.
If you can return them or exercise the warranty do so. If / when you get new ones DO NOT completely discharge them like you would NiCads. Lith-Ion batteries do not have the "battery memory" issues that NiCads have which means you don't lose running time if you don't fully discharge the battery unit prior to recharge. Completely discharging before recharge will ultimately kill them. Use the 1815X till almost dead and then charge it. It is also recommended Lith-Ion batteries not be stored fully charged i.e. charge the 1815X fully, drive a couple bolts or screws, remove the battery unit and then put it away. Do not leave battery unit plugged into the tool when you put the tool away. This will discharge and kill the battery unit.
There are non-Hitachi substitute batteries now on the market. I'm guessing the same precautions apply but I don't own one of the replacements so I don't truly know.
The actual batteries in the Hitachi BSL 1815X are Sanyo UR18650SAX lithium ion batteries. Lithium Ion cells aren't all that easy to get commercially because of handling & safety requirements. Not certain if you can take apart the 1815X and swap out the bad Sanyo cells.
Drill battery charger doesn't work
Hi Firemedic13;
Most chargers like yours have a fuse inside them. Remove the screws that hold the charger together. The fuse will be on the low voltage side of the transformer. Un-solder and replace it with one of the same value.
If the charger is not held together with screws (doubtfull) you will have to carefully cut along the seam where they were glued together. A dremmel tool works good for this. After repairing use some ABS pipe glue to re-seal them together.
If the fuse is not blown then the unit will require testing by someone that is proficient with a multimeter. Most times it is the transformer that has fried a wire. If the sides of the transformer have any burnt spots on it then it will be the culprit.
Hope this has helped.

Batterys dont keep there charge
before you dump those batteries, check the charger. If the battery when charged runs the tool but dies out quickly then you are probably right. If the battery never seems to be charged at all, then it may be the charger.
