HITACHI Laptop AC Adapter,HITACHI Replacement Power Adapter

Problems with hitachi laptop battery?These tricks & tips might be helpful

• Keep the battery cool and don't leave it in the sun
  Lithium batteries come with built-in circuitry that protects them from overheating, so leaving a laptop to charge overnight or over a couple of days won't damage it. However, if a hitachi lithium battery is over-charged for too long (eg a week) it will start to heat up. Overheating is a lithium battery's main enemy and could result in permanent damage to the battery. The battery can also get overheated if your hitachi laptop is left in the sun or near a radiator, so avoid doing this as well.
• Keep the AC power adapter plugged in only when you need to charge the battery
  One of the most common issues with laptop batteries is overheating. Not that the batteries are designed poorly or improperly but due to, in most cases, user wear and tear. While the laptop is using the AC adapter for power the hitachi battery acts as a back up in case of a loss of power or accidental unplugging. During this AC power use the battery becomes hotter than it would if being used independently. To lessen the chances of this overheating, which leads to a shorter life expectancy of the battery, keep the AC power adapter plugged in only if you need to charge the battery while using the device.
