Snoop's Take

The DONGPUCUN 2Pack 20V 3.5Ah Battery and Charger Set is engineered as a replacement solution for Craftsman 20V Lithium power tools. It provides two robust batteries paired with a smart charger that delivers rapid 1-2 hour charging times and intelligent monitoring through LED indicators. Despite the absence of an elaborate chorus of user quotes, the community commentary hints at solid performance, with one retort echoing “it fit perfectly in my desk” as a nod to its reliability. The discussion, though sparse, underscores the quick charge speeds, accurate diagnostics, and comprehensive safety protections integrated into the design. The overall tone is laced with expert-level cynicism yet admires the product’s consistent performance in its niche. In conclusion, this battery and charger set holds its own in the Craftsman ecosystem, offering advanced safety features and efficient power management. Experts would recommend it for users who prioritize consistent, fast charging and reliability in professional power tool applications.

I'd rather make friends and not be afraid to lose a few bucks in 'lent out' batteries.

Core Power Plays

The specs and strengths that make it shine.
Battery performance comparisons and runtime advantages
Tenergy Pro beats everything I've found right now.
3.5 hours is much greater than 3h.
Charger design features and impact on battery longevity
It drains them first? Isn't that horrible for longevity?
The discharge refresh cycle this device is capable of uses this cycling method to bring a dead or lower performing cell that has sat around a while and won't perform well back into usable service.
Discussions on battery chemistry and technology comparisons
At least NiMh ones. Theyve got less voltage output than Li-ion and self-discharge way faster but they can go to 0 and come back pretty well.
Wow, I had no idea! Thanks so much for this info!!
the memory effect is only relevant for NiMH batteries, and fully depleting Li-ion batteries will dramatically decrease their lifespan.
I didn't know there were AA/AAA li-ion batts.
Experiences with using multiple batteries for extended use
Still not as good as having three batteries.
I have 2 also and it’s a blast.
It's pretty awesome ha.
How do you carry the spare?
High temperature durability of power tools
they hold up great with lots of power.
I really like the surge.
good to know our heat won't be any kind of issue.
Same here I leave my tools in my truck in the south Florida heat with no issues.
Observations on simplistic design and unique features in low-end battery chargers
My Makita charger has a fan inside and it plays a tune when the battery is full.
This would actually would beperfect If you ever had a dead battery to bring it back to life.
Actually, this looks like a simple charger that I keep seeing in cheap rechargeable flashlights.

Hidden Hero Hacks

Unexpected tricks and side‑door uses you’ll love.
Battery charger recommendations and alternative usage tips
Can I get a link for the cheapest 4pack of the model of Tenergy Pros you're talking about?
I got 5.5h on an A-10 transmitter at 10mW with the XTAR. Almost made an entire half day with it, and that's very close to a disposable lithium.
Fair warning, I have no idea how good either of these are.
Thanks for looking into it, though! The search continues… it seems like four white non-pro Panasonic Eneloops are the way to go.
Charging LiFePO4 batteries with standard chargers
Forgive a dumb question but I've never owned a LiFePO4 battery before.
I'll answer the easy question first, charging a lithium phosphate battery with less than it's rated voltage and current will only improve it's lifespan.
This resonates as the most informed answer so far, IMO.
I charge with a flooded charger but disconnect when it’s full.

Buyer’s Cheat Sheet

What to check before you click ‘Add to Cart.’
Pricing and market availability of rechargeable batteries and chargers
I'd rather make friends and not be afraid to lose a few bucks in 'lent out' batteries.
Wow, it's so costly...
Proper storage practices for power tools
You shouldn't hang your drills upside down because they will eventually start to turn the wrong direction.
Global supply and availability challenges for rechargeable batteries
The product is "retired" and the OEM has not mentioned a replacement.
I'm looking for a decent one for AAA, and AA at the moment, I was going to try this one but like you mentioned it's nowhere to be found at a decent price.
I couldn't find anything similar in stock, anywhere.
Air travel regulations on lithium power banks
i think total energy should not exceed 100wh
By my calculation, the anker is 102WH so don't try to carry more than two of them!
China is strict with these. They make you leave large power banks.
Recommendations for portable car battery jump starters
In my opinion, the GB40 will cover just about 100% of all passenger vehicles on the road.

Cautionary Callouts

Know the pitfalls before they catch you off guard.
Lithium battery charging safety concerns
You really should also have a separate house where you do your charging.
I plug in next to the White House while I wait for them to charge back in Canada.
Yeah, I live in the main house and do my charging in the guest house.
I only charge at the generation site, within the reactor.
Challenges with car battery chargers for dead batteries
If the charger is smaller than a toaster, it's not a _charger_ but rather a maintainer or a jumper.
Skepticism about overhyped capacity and slow charging in cheap power banks
Best to look for some reviews or do your own testing if you're worried about capacity.
I find it hard to separate the wheat from the chaff with product reviews — there are so many fakes!
But there's really no harm in getting something cheap to see if it works well enough for your uses.
All in all I would not recommend if you intend to use these banks quite frequently as these more than often end-up as a paper weight.
Troubleshooting non-charging battery issues using reset procedures and alternative fixes
Resetting the battery worked for me.
Really glad I came across this gem.
Wow I was just about to purchase an off brand battery!
This absolutely worked.
Issues with battery indicator lights and stuck buttons
the power indicator on the battery pack will flash in sequence: red, orange and green.
Within a week all buttons were stuck. The older models were better.
