New recargeable NiCad batteries should always be conditioned properly
before you use them.otherwise they will develope a memory and will not
recharge up all the way again.Here is how I do it and it always works
for me.Charge the batteries up and put them in a flashlight.(torch) Turn
on the flashlight and let the batteries drain all the way down.Do that
at least three times,you will notice the flashlight stays on longer each
time.(try it,it really works) Whatever you use the batteries in,always
let them drain all the way down before you recharge them back up.Once a
month,put the batteries in a flashlight and let them drain all the way
down and then recharge them.My favorite brand name of batteries are Ray
O Vac. www.rayovac.com Eveready battteries are good too.
cuhulin,not a battery expert,but I do know what works for me
