Convert your Ni-Cad Milwaukee Tools to Lithium-Ion

Posted by on November 10, 2006

Milwaukee Tools just started offering a cool upgrade for existing customers with Ni-Cad tools. It’s a kit (2 batteries and a charger) that allows you to power the older Ni-Cad tools with their newer Li-Ion batteries. For around 2 bills, that’s not bad at all if you’ve got several tools already that you’d like to give the longer run-times.

What’s even better is that they’re offering a 5 year warranty on these batteries. with the first two years being exchange replacement.

Why would you want to do this? There are a couple of reasons. The biggest being that the weight of Li-Ion batteries is considerably less than Ni-Cad, which means your tool using experience will be much more pleasant. Li-Ion also have a longer runtime and more charges in their lifetime.

While this isn’t a “Throw out your old working batteries” type of an upgrade, if you’ve got some aged cells and are looking to freshen your personal battery inventory, this appears to be a great way to go. If the other manufacturers offered this, I’d be all over those, too. It’s hard for me to pass up new geek toys.

For more information, including current pricing, you can take a look here.

    >Li-Ion also have a longer runtime and more charges in their lifetime.

    Wrong. Li-ion has 1-1.5 year shelf life, and can only take 300-800 cycles (makita, milwaukee), where NiCd (dewalt, makita) can be 1000-1500, and lasts well over 2 years. Milwaukee’s claim “2000″ charges on V28 line is bogus. After 2000 cycles you will have 10-40% of the original capacity, if not 0. I use cordless drills at work every day, we have about 30 various 18v dewalt drills and all of them are 2-3 years old, and batteries retain 60-80% of the original capacity. Batteries are recharged at _least_ once a day.

    Millwaukee and it’s parent company Ridgid or TTI who also is Ryobi are not very smart in interchanging NiCad & Lion batteries in my opinion as the heat rating for Lion batteres is greater than NiCad. This means that the tool will have problems due to the higher amount of heat running the tool (consumer reports) unless they have dumbied down their batteries somehow. These manufacturers have not redesigned the tool, the battery, & the charging system to be in balance with each other like say – Makita has. No one else can claim 40% less weight & 280% more work like those guys can. What can These other companies really compare themselves to other than themselves? The media needs to test, and re-test apples to apples to show who is pulling the wool and who has the best performance, per battery, power, torque (measure it all the same), who’s batteries charge the fastest and the fullest, how much work can be pulled from the batteries? Just because you say you have a 30 gallon gas tank does not necessarily mean you can use 30 gallons. What does the charging system do? Does it analize the battery? Does it insure you have an optimum charge? When a magazine does a test on tools, are they considering their sponsors or advertisers? Are they being totally objective? I know being unbiased is a tough thing to do, but this is part of journalism. Well, I am off my rant. Prove me wrong! Do the tests, be objective.

    Thanks for sharing your opinions.

    First off, we’re not a magazine. We’re an online retailer.

    Secondly, all the claims you’re mentioning were not in this article at all. If you’ve got a problem with a magazine, please take it up with them.

    I just plan on selling these to people with existing Ni-Cad tools because they are a decent upgrade and our customers have been pretty happy with them so far.

    I was always told that you can not use lithium batteries with a nicad drill. I know you can use nicad with lithium drills, but not the other way around. Is this true, and if it is, what is the difference in these batteries.
