Cordless Drill Batteries and Your Drill

When looking for the perfect cordless drill you need to be very careful that to look at every problem before purchasing.  You will also want to look at which cordless drill batteries will last the longest.  For a long time, professionals would not touch a cordless drill.  Most professional did not enjoy starting jobs and having their drills stop in the middle of the job.  Also, the burn out rate for these batteries was very high.  A professional could go through 1 or 2 batteries every other month.  As a result, professional craftsman would opt to have wired drills that one had a longer life and two held up to the rigors of the job.  What made it worse was the fact that the batteries cost so much compared to just getting a new drill.  With cost so high, a new market was born for refurbished cordless drill batteries.

Cordless drill batteries have gotten better.  Now, even the cheapest batteries tend to last months or even years.  But the merchants had to do a lot to get them to this point.  That work has started paying off.  Now, craftsmen are tending to pick cordless drills over wired drills.  Thus, giving them more freedom to not have to worry if a work site has the electricity needed to use their drills.

Cordless drills have also taken on the Lithium-Ion battery technology.  Lithium-Ion are a type of battery
composed of Lithium, the lightest metal and the metal that has the highest electrochemical potential. Lithium, however, is an unstable metal, so Lithium-Ion batteries are made from Lithium ions from chemicals. Because of its lightness and high energy density, Lithium-Ion batteries are ideal for portable devices, such as notebook computers. In addition, Lithium-Ion batteries have no memory effect and do not use poisonous metals, such as lead, mercury or cadmium.  The only disadvantage to Lithium-Ion batteries is that they are currently more expensive than NiCad and NiMH battery packs.

That being said, manufacturers are also equipping drills with the NiCad and NiMH battery packs.  NiCad battery are a rechargeable battery with a nickel cathode and a cadmium anode.  They are often used in emergency systems because of its low discharge rate when not in use.  NiCad batteries are great for on the job recharging.  If done right, charging a NiCad battery could take as little as 4 hours.

Cordless drill batteries are also evolving.  I am sure manufactures will even cut down the recharge rate to 2 hour or below.  Some day, I wish.

does extreme cold weather harm lithium ion batteries?

i have an 18 volt lithium ion cordless combo kit from ridgid and i keep it in my service van, in wisconsin it gets down to 30 degrees below zero in the winter and i'm wondering if this will take service life out of the batteries

Such cold temperatures could harm the battery. Li-ion batteries are designed for operating environments from 0º C or 32º F to 60º C or 140º F. Usage in extreme temperatures (either hot or cold) can cause premature degradation of the cells or electronics within the battery.
