Does the $25 cart discount work for any other Dewalt tool items, or just this particular pair of batteries?
OK, I actually stumbled on another amazon promotion almost by accident, then had a really hard time finding it again. It's buried under a few select products, but here is the promo page for $25 off total of $100 or more of select dewalt products.

Anybody has had experience with 3rd party replacement batteries? Good or bad? Recommendation? I have been waiting for a deal on these batteries, but 2 for $100 seems too expensive to me.

Thanks for any info!
My father purchased 6.0ah makita knockoffs on flebay and they are trash.... he didn't take my advice.

Are these batteries safe to be left on a DeWalt charger while not in use?

Yes. See Dewalt's explanation here: https://www.dewalt.com/dewalt-dna...ttery-life

So ive only ever used Makita cordless tools and i recently picked up a DeWalt set, i have makita batteries that have been used daily for almost 10 years, are you saying its common for DeWalt batteries to only last 3 years?

There's not a battery on earth that will last 10 years without losing significant capacity. I would say 3 yrs is very typical for a good quality battery.

I didn't say they didn't loose capacity but they are used in a professional environment every day and still going strong. We have 8 batteries in the rotation between 2 impacts 2 drills and 2 Reciprocating saws and the newest battery is like 4 years old. Never an issue with running out of power.

That's awesome. I guess I can't say if the DeWalts will go that long. In general, I think they are pretty solid.

typical DeCrap batteries

you'd think for what this company chargers for its batteries, that they would at least last longer than a few years

Li-ion batteries, as well as nimh, generally last longer if they are used regularly, drained and then fully charged again. Where you usually get into trouble is when they sit around unused for months, or stay on a charger for days on end.

Typical Lithium Ion battery life is about 500 or so charge cycles or roughly around 3 years. And that is with very heavy use. Used in drills, circular saws, reciprocating saw, metal grinder, and jig saw all cycling between just 2x 5ah power packs. That is pretty damn good. And they still hold charge just not as well as they once did.

Going from milwakee to dewalt to makita I think that you will find the same batteries inside battery packs. I believe that most use either panasonic or samsung Li-Ion batteries. So with similar use it doesn't matter which company you go with. All will die within a similar time period given similar usage. You can't go wrong with any of the big tool manufacturers battery powered tools these days.

What do you mean you'll need another charger
Hey. The charger that came with my combo kit I got from Home Depot has a slower charging rate, apparently. So the combo battery/charger deal on Amazon seems to be a great deal, since that charger that comes with the 5A. battery charges a lot faster.

Plus, it'll be convenient keeping one connected in your garage, and then using one for transport.I'd say transport with the faster charger, and keep the slower charger at home when you won't "Immediately" need your batteries but only want to charge over night, etc...

Not true. Lithium cells degrade in a way similar to lead-acid in that they don't like to go through a full discharge-recharge cycle. That's why most are rated for XXX number of charge-discharge cycles. Additionally, Lithium cells require a more sophisticated charging circuit to prevent over-charging and over-discharging. Over-charging can actually destroy the battery (sometimes with pyrotechnic results). Over-discharging can render them unable to accept a new charge. This is why a lot of knock-off batteries die after a few uses, they don't include the proper monitoring to prevent over-discharge. When the battery reaches its max charge the charging circuit stops the charging process.

For storage, Lithium cells are about the best around. If you plan to shelve them for long periods of time, it's recommended to store them with 50-80% charge. They should last for a long time in that configuration if there isn't any parasitic drain (like you see in built-in batteries on things like laptops or tablets).

NiCad batteries were the ones that needed full discharge/recharge cycles because they would start to form a insoluble crystal layer at the point where the discharge cycle ended and the charge cycle began. Eventually this would create a new "end point" for the discharge where the battery would stop working.
