| How Temperature impinge on the DVD Player Battery? |
By:

Electronic devices do get affected by cold/hot weather. Any extreme is bad. It is hard to say if it will be long term damage or a temporary one. Portable DVD battery will be abnormal if its temperature is too high. At high temperatures, performance of the DVD battery will be degenerated and battery service life will be shortening greatly.
Normally, all electronics malfunction when they are exposed to chilly area because the cold and chillness causes invisible moisture which causes a starting problem. Placing your DVD player, audio system or other electronic devices near the window or the A/C, probably could create such an atmosphere for your electronic device. The cold makes the signals in the wiring incapable of functioning properly. It doesn't need to be warm but it can't be too cold. Low temperatures will obviously reduce Ni-Cd and Ni-MH battery discharge rate. At -20oC, electrolyte is at its freezing point, and the battery charging speed will greatly slow down. At low temperature, charge will raise the internal gas pressure and probably unseal the safety vent. Ambient temperature of 5oC to 30oC is the best range to get effective charge.
Try to insulate your room with heaters or anything which can give out heat so that your room is not that cold. Make sure that the temperature is not below freezing or it might affect your electronic devices including your portable DVD player. Don’t keep DVD player hidden in car trunks. If your DVD player experiences extreme temperatures, allow them time to warm to room temperature before operating them.
The primary protection features for the portable DVD player are over-voltage, under-voltage and over-current protection features. The primary protection features are always integrated into the battery pack, and are the responsibility of the cell itself, as well has the battery protection circuitry in the pack.
One of the most popular safety features in hand-held system designs is the monitoring of cell temperature. High temperature levels are the main source of Lithium-Ion battery instability, therefore battery packs incorporate a thermistor element that can monitor temperature levels and provide this information to the outside world. In response to this, many of the charging ICs have the ability to read this thermistor output and suspend charging when the cell temperature is outside a battery manufacturer’s specified range.
Most of the DVD batteries incorporate additional protection in their designs. System philosophy will define the necessary secondary protection features for a specific design. Having secondary protection allows for higher system reliability and meets the most stringent safety requirements in the industry. Now-a-days, you can get portable DVD player batteries having no memory effect and which can be recharged at any time regardless of the amount of discharge.
Some of the precautions can be adopted to use your DVD battery for a long time - Avoid placing the battery under high temperature or next to heat-sensitive materials. Always keep them away from the direct cooling cause such as A/C. Do not subject the battery to extreme temperatures, or it may cause damage to it and may affect the performance of the battery. Do not leave the battery in your DVD player if it is not being used for a period of time. Always try putting the electronic devices inside the Styrofoam. This will keep it on a right level of cold/hot weather condition. |
