DEWALT DW9116 7.2-Volt to 18-Volt Pod Style 1 Hour Battery Charger

Product Description

Amazon.com Product Review
This is an amazing little charger that literally breathes new life into your failing DeWalt batteries. It revitalizes everything from 9.6 volts through the big 18-volters, but what's so great about this charger is that not only can it be used as a standard quick charger, but if you leave a worn-down battery in for four to 10 hours, the charger conditions the battery with a tune-up mode, and at completion, it automatically converts to trickle charge, so you'll never damage a battery by leaving it in the charger too long.

Diagnostics with LED indicators give you the battery status at a glance: charged, charging, power line problem, replace pack, and battery too hot or too cold. It's got a small footprint, which is always a plus, and the price is look-twice-and-rub-your-eyes cheap.--Kris Jensen-Van Heste

5.0 out of 5 stars "Tune-Up" Makes this the Better Choice, September 26, 2000

By	Al the Pal "Al the Pal" (The Fruited Plain, United States) - See all my reviews (TOP 1000 REVIEWER)

I traded up to this charger after one of my old ones quit. The "tune-up" mode really does make a difference. I tried a side by side test with my remaining old non-tune-up charger. I charged two depleted 12v batteries for 10 hours, using the "tune-up" mode on this charger. I then ran them in the same drill, and there was a noticable increase in rpm and torque with the "tuned-up" battery. The "tune-up" mode does take 8 hours, but it is only necessary every 8-10 charges. As DeWalt explains, the cells in the battery are wired in series and the "tune-up" charges the downline cells completely, where fast charging only fills the first few cells. All cordless batteries are a series of 1.5v batteries enclosed in a case. To get a full charge, all the individual batteries need to fill completely.

If you have older batteries, this charger will give them new life. It is a worthwhile upgrade even for new batteries, as it will give them better performance and perhaps, extend their life.

5.0 out of 5 stars Throw away your old charger!, January 19, 2004

By	Christopher Nash "Fantasy Fanatic" (Whiteman AFB MO) - See all my reviews (REAL NAME)

I purchased this charger at the same time I bought my 14.4 cordless drill (Firestorm). This charger fully charges your Dewalt or Firestorm batteries in less than an hour (depending on how low they are when placed in the charger). My two batteries are still going strong after more than three years of frequent home use (the tune-up mode definitely helps).

Never use the 6 hr battery killer that comes with your cordless tools. This charger is definitely worth the money, considering I would have spent at least twice as much on new batteries.

3.0 out of 5 stars Firestorm owner, September 13, 2007

By	Dr. Bull - See all my reviews

I bought this battery charger hoping that it would work with the firestorm batteries of the same type because the chargers sold by black and decker are hard to find and the ones that offer multiple voltages are even harder to find for this type of battery (i.e. post-type). I would like to reassure any other people in my situation by saying that this charger does, in fact, work for the firestorm batteries. As mentioned in previous reviews, it also functions well to restore the battery to better functioning.
