Consult any labels carefully, particularly any WARNING labels. The labels are largely self explanatory. Reading the labels will save you a great deal of time and help prevent damage to your equipment.
Review carefully the following specifications printed on the battery:
Voltage - This is usually a multiple of 3.3. for example 3.3 Volts, 6.6 Volts, 9.9 Volts, 13.2 Volts etc. Ensure that the battery voltage is suitable for use with whatever you connect the battery to.
Capacity - This is stated in mAh for example 1100 mAh, 2300 mAh etc.
MAX CELL CURRENT - A123 Cells are capable of 30C continuous current and 60C current for up to 10 seconds. The actual 30C and 60C current values in Amps are stated on the battery. These values are large and they are correct for the cells themselves but the battery pack assembly should not be assumed to be able to provide current at these levels. Often the manufacturer of the connector or wiring or internal welding strips has lower maximum current values. Look for lower limits stated on the battery, for example "Connector rated for 45A". Ensure you test to ensure that your application does not exceed either the 30C rate or the third party component rating (such as the connector) whichever is lower.
MAX CHARGE - A123 Cells can be charged at up to the 5C rate. The actual 5C current value in Amps is stated on the battery. Make sure you do not exceed the MAX CHARGE current when charging. A123 cells perform best when balanced. The balancing voltage should not exceed 4.2V/cell. This is best done at a low current value such as 50mA or less.
Connectors:
If your battery was supplied with an output power connector such as an Anderson Power Pole or a Deans Connector we strongly suggest NOT changing the connector. If your intended application requires a different connector we suggest using an adapter to mate the battery to your device.
If your battery was supplied with output power wires only (no connector) you need to install your choice of connector:
-
We strongly encourage the use of Anderson Power Pole connectors using 45 Amp contacts professionally crimped into place or Deans connectors professionally soldered to the power wires of the battery.
-
Remove the insulation from only one wire at a time to avoid the wires every contacting each other. Contact will create a high current short circuit that can cause a fire and damage your battery.
-
Ensure that the red wire is joined to the positive (+) connector and the black wire is joined to the negative (-) connector. Incorrect polarity will damage the battery and devices to which the battery is connected and may cause a fire.
UNPLUG WHEN UNATTENDED. DO NOT SHORT CIRCUIT.
