How to protect you Hitachi mn1 Battery
Simply run your Hitachi mn1 Series Battery until it's FULLY discharged and then fully charge again. After extended periods of non-use, you should do the same. Lots of little charges followed by partial discharge will decrease the life, performance and capacity - in reality though, this is how laptops are usually used and this may be unavoidable.

Why Hitachi mn1 Battery not charging
Recently find so many toshiba laptop batteries not fully discharged from user forum, how to check the problem?
Normally the DC-DC convertor or power board controls the charge circuit in laptops. This will control the distribution of power in the laptop and ensure items such as battery charge are working. not charging might have something strange such as your power adapter running a little low on voltage, we get units into our workshops quite often that fail to charge batteries correctly and find the power adapter is not supplying sufficient power.
If thats the case its generally a cheap fix, replacing the power board is often a more expensive option.Ideally you could do with either finding someone with a power adapter you can try or looking for a reputable company that would perhaps give you a free quote.
We suspect that first as when the units open and drawing most power the adapter might be struggling to provide sufficient power, its very difficult to measure the output as the adapters are generally worldwide compatible so they adjust themselves depending on the input voltage and the load required.
