You can tell by picking the up, the C and D cells weigh the same. Nicads are not too swift when they get cold. Also they have a memory effect. If you only discharge them 10% before you charge them several times, they will only hold about 10% charge. By the way, a nicad D-cell should be a 4 ampere battery. If treated properly, nicads only last about 3 years typically. If after using nicads several months and you notice that they do not hold a full charge, they have developed a memory for the use and recharge cycle. You can recover the nicads by leaving the appliance on for about 12 hours to get a deep discharge. Charge the batteries for 24 hours. You should do a deep drain and recharge every 3 months.
