How to use a battery correctly?

  1. When recharging a new battery or one that has not been used for months, your charger or device may indicate the battery has been fully charged after a few minutes. Please do not disconnect the battery and charger, because the recharging is not completed yet. The charger will recharge the battery in about 10 hours. This is not a problem. The same battery will be fully recharged within 2-3 hours next time. The ibm thinkpad t21 series battery will require 3 to 5 charge/discharge cycles before achieving its rated capacity.
  2. When battery not in use, remove it from your device and store it in cool dry place.
  3. Do not short-circuit terminals. Most of our laptop batteries are protected with an internal self-resetting fuse, but short-circuit may still cause severe damage to the battery. Be careful where you set the battery down.
  4. Keep away from fire and other sources of extreme heat and do not incinerate when disposing of the batter, otherwise it may explode.
  5. Do not expose battery to rain or moisture.
  6. Do not drop, hit or otherwise abuse the ibm thinkpad t21 series laptop batteries as this may result in the exposure of the cell contents, which are corrosive.
  7. Do not use battery at temperatures below -10C (15F) or above +40C (105F). Use of ibm thinkpad t21 series batteries at very high temperatures will activate the safety circuit disallowing use.
