Are you certain the charge is working? And, sometimes new batteries are bad. It sounds like the charger is not working. All batteries will rejuvenate a small amount without use.Are you certain the charge is working? And, sometimes new batteries are bad. It sounds like the charger is not working.

A fully working 18v Dewalt Battery will only take 90 minutes to just over an hour to fully charge from going flat. This fully charged battery should last about 4 hours of use (depending on the load). So the answer is 1 hour.
I have just had a similar issue I left the drill unused for a period and when i placed it in the charger the charger showed the battery as charged after about 15 secondseconds.
Following a internet search i found a site that suggested for a imlar problem with a camera jump starting the low battery with a 9 v battery. I had a spare from the drill which was fully charged so placed a contact from + to + and - to - and held for about 2 mins. I then placed the battery back in the charger and it started charging. Running the battery down as we speak to recharge again well worth a try. If you dont have a spare maybe the 9 v would work
Depending on how old or more to the point how many times you have already charged the battery, it may be worn out. All rechargeable batteries do reach a point where they won't charge up anymore. If you have fully discharged the battery and tried to fully charge it up again and it won't take a charge or only lasts a few minutes on a charge it may be time to recycle it and buy a new one.
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.
I have several 18v tool sets and for the most part I'm quite satisfied with their performance. I currently use Bosch and Ryobi.
When used with the drill, a battery can last me the whole day. On the other hand, the sawzall will eat them up pretty quick.
The thing I've found common to all brands is that it is absolutely crucial to make sure the batteries are fully charged before they get used for the first time. That first full charge seems to set the bar for subsequent charges for the rest of the batteries life.
I too, have tried the discharge/recharge thing. No help. I can only suggest a new battery and letting get all it can take from the charger the first time out of the box.
Since I've been doing that, I rarely even think to bring my charger to job sites, there's that much of a difference in performance.
the battery's are most likely dead, (like the real dead) after many uses of rechargeable battery's they slow stop holding charge at all, make sure when you get a new rechargeable battery you fully charge it once and fully discharge it once this will increase batterys life time
