I posted about my 3680 not charging and i got a solution that the batteries are lithium ion and tend to lose charging abilities and that i need to replace them. I understand this but would the batteries cause the computer not to charge ONLY while its turned on? Because it charges perfectly while it is turned off.

Frequent Charging Shortens Battery Life Frequent charging shortens the life span of a Lithium ion battery. Batteries should be charged only after they expend all their power. b> Switching Batteries Switching batteries helps preserve battery life: If a cell phone or computer user puts in a spare battery while separately charging the primary Lithium ion battery, that helps extend the life of both batteries. b> Removing BatteriesMost laptops charge the battery when a user plugs in the AC adapter. Users can adjust this setting by changing the power options. Windows places this option in the Control Panel, while the Gnome Linux desktop places power options under "Administrative Tools". Cell phones incorporate their own power-saving features that the user usually cannot control. b> When to Replace a Lithium Ion BatteryIf a laptop battery does not hold a charge for more than a few minutes, a user must replace the Lithium ion battery if he wants to use the computer without an AC adapter. Other Ways to Extend Battery LifeStoring a battery in a cool, dry environment causes a lithium-ion battery to last a little longer and reduces the frequency of needed battery replacements. Hope this helps.
Li-ion Lithium ion batteries amount conspicuously added than added two way radio batteries, and at the aforementioned time they are beneath abiding and added chemically volatile. Also, Li-ion batteries crave their own chargers (NiCd and NiMH batteries can generally use the aforementioned charger) and at abounding ability can irreversibly lose amid 5-20% of their accumulator accommodation annually.
NiCd The capital disadvantage of a nickel cadmium array is its susceptibility to "memory effect," acceptation that the array gradually loses its accommodation for abounding recharging if it is again recharged afore its accommodation has been absolutely drained. Because of this, nickel-based batteries (both NiCd and NiMH) are almost aerial maintenance. Also, the cadmium in NiCd batteries is toxic.
Your system definitely uses a lithium ion battery.
Over their lifespans, lithium-ion batteries can lose the ability to hold a charge. After a few years, some batteries will last only a fraction of the rated runtime. Replacing a battery is relatively simple; most pop out from the bottom or back of the laptop.
Many retailers, however, charge hundreds of dollars for a new battery. Sites like batteries.com specialize in discount laptop batteries and can save you money on a brand new battery for your laptop. For example, a Dell Latitude D620 Li-ion battery costs $139 on Dell's Web site and $83.99 on batteries.com, as of press time. (The company even offers a two-year warranty and 45-day money-back guarantee on all laptop-battery orders.)
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.
Some lithium-ion really loose their life easily and sometimes quickly.They are affected by temperatures too.I noticed that when I am charging the batteries tend to heat up and I found out they loose their power quickly when you let them charge and leave them warm.Secret to of prolonging their life is after a full charge zip lock it and freeze them.Of course dry them upon use.Do try a new set of batteries it will resurrect your camera back to life.
