Digital video camcorder have been great strides into the family, many ordinary families have a personal mini "Digital Imaging Workshop", can produce digital images CD-ROM belong to their own arbitrarily. However, in the use process of digital camcorders, we will find such a problem - the current digital camcorders are generally used rechargeable lithium-ion COMPAQ DP390A battery with a high price, the major manufacturer have "little words" in the products specifications about the proper use of lithium-ion battery . The usage many people get from a variety of channels are not very correctly, so many people' original COMPAQ DP390A battery is closer to "scrap" when get a not long battery life time, and had no choice but to spend lot of money to buy second battery, that adds much trouble.
In fact, although there are a wide range of different models batteries currently on the market , different manufacturers use different battery models, and sometimes will lead to consumers get no idea choose what to do, but the method in use is more or less the same. Today, we are on to explain the proper use of a COMPAQ DP390A digital camcorder battery, and hope to be helpful to everyone.

1. When we buy a new digital camcorder, the first thing to do is charge the lithium batteries, battery internal management circuit charge the rechargeable COMPAQ DP390A lithium batteries is a complex process, it is necessary to ensure that lithium batteries' full performance, but also to ensure that rechargeable lithium batteries should not have charge too more, because if the the charge current is too large, or the charging time is too long, oxygen generated consumped too late, may result in hypertension, battery deformation , leakage and other undesirable phenomena, even cause a serious explosion or fire, so must be in accordance with the right method of charging.
2. Many people consider the previous three times use of lithium batteries should be charging more than 16 hours, that can be fully activate the DP390A battery. in fact, it is only popular Ni-MH or Ni-Cd battery charging method not apply for lithium-ion batteries. Since such a battery with lithium polymer as its core have no memory effect, so only about three hours charger is entirely. On a general chargers sell with the camcorder have a display function, if the show it has completed charging, you can unplug power supply, do not have to wait such a long time!
3. In general, lithium batteries can be recharged 300-500 times, according to the different methods and frequency of use, may be your digital camcorder battery can be used a few years or only one year, so the routine maintenance is importance. According to IEC standards require, the DP390A battery pack should be store under the conditions temperature of 20 + -5 ℃, humidity of (65 - +20)% , to avoid placing in very hot space. Generally speaking, the higher the temperature of the battery storage the lower capacity of the remainder, and vice versa. So we had better make the COMPAQ DP390A camcorder battery stored in low temperature, dry place, especially in travel time more attention should be paid to keep the camcorder battery, and try to avoid the battery store with metal objects to prevent the occurrence of battery short-circuit; Battery could become dirty easily when travel out , that may cause the "loss", in order to avoid power drain problem happen, we must pay attention to maintaining the battery at clean both ends of the contact point and the internal DP390A battery lid. If the battery's surface is dirty, then we must use a manner and soft, dry clean cloth gently wipe the surface of the battery timely to maintain the battery clean.
4. When the long-term non-use of the COMPAQ DP390A battery, we'd best take down the battery from your digital camcorder, because at this time even if the digital video camcorder was switched off, the system will still have a low battery current output, which would reduce the battery life. Suggested discharge part of the power of the battery before long-term preservation in order to restore the initial battery capacity and discharge performance. Attention should be paid to avoid a complete discharge, because lithium batteries are a low-maintenance batteries, the part of the discharge the battery is make more durable than completely discharge , if possible regular completely discharge should be avoided, that is to say not to use the camcorder battery until automatic shutdown, recharge should be timely as long as the low electricity shortage alert.
5. It may have disastrous consequences If your lithium batteries have been frequent discharge completely , especially in high-current-off place or repeatedly put off, and it can not even short-circuit discharge, because such damage on the battery a far greater role. because the Internal pressure will rise and cause reversible negative electrode active material damage, even can only be part of recovery if charge, capacity will be significantly attenuated, with the passage of time, the time your lithium COMPAQ DP390A battery can supply will be a growing shorter!
