Macbook Core 2 Duo Battery Not Charging

I immediately unpacked, plugged-in, and started testing and charging batteries when the Watson Duo arrived. Mounting a battery with the device unplugged from power, the screen reports the percent remaining charge left on the battery, and pressing Test, the measured voltage from the battery. Finally, no more balancing VOM, +/- probes and the battery to track voltage loss! Plugged-in, the charger reports the same information for each battery on the display, and indicates it's charging by the flashing top unit in the graphic battery indicator. Love it!! Wanting to change battery plates, I held the charger in my hands like playing a game played using thumbs, and pushed one of the plates towards the back of the charger, like I would with any of the plates for my eight year old Pearstone plug-in-the-wall chargers. The plate would not budge! Tried the other plate on the other side of the Duo, same thing!?!? Confustion ensued, LOL!! The manual has a minimal graphic showing installing the plate, not taking it off. So, after fiddling awhile and dismissing the use of screwdriver, it was back to thumbs pressed and squeezing hard against the corners of one of the plates, then progressively increasing the pressure applied, until it popped free! It took several similar remove of a plate from each side of the Duo using this technique the plates supplied with the Duo were easily removable. The good news is that my Pearstone plates are the same plate as the Watson plates. They fit perfectly on the Duo, and mount and dismount easily. I really like the features on this charger; the voltage/capacity display, the USB power/charging output, the car adapter input and being able to charge a different type and/or voltage batteries at the same time on this charger. Highly recommended this Watson Duo for its simplicity, quality and features. I always look for great value over the long-run, and this charger overwhelmingly fits the bill. Thanks, AGAIN, B&H!

I purchased the Core SWX 98Wh battery about 3 years ago and it is still able to keep a long charge after many charging cycles. I needed another battery since I got a second camera. I have used this battery a few times now and it seems to go forever on a single charge. I usually have a BMPCC 6K along with a 7 monitor and I get about 5 hours of use on a single charge with that setup.

This is an awesome powerhouse of a computer. I was coming from an old Core 2 duo iMac and the jump to the Mac Pro is amazing. No longer do I watch the spinning beach ball. It's a dream for using Adobe Lightroom 3, Photoshop CS5 and other processor heavy apps. I upgraded to 12 GB Ram which seems to be ideal. The Mac pro also runs Parallels with Windows 7 really well.

Bought this for my wife which has been using a Core 2 Duo, GT 630, 8GB DDR3, etc since 2012 until 2019 before we got married. Her seeing the difference in creating contents really marked a beautiful smile on her face and that's what matters. Thanks B&H for making it seamless. Appreciate it very much!

If you're working on a 2010 MBP 13' Core 2 Duo (MacBookPro7,1), then this is the memory upgrade kit for you. What was a slow, sluggish laptop is now just as fast or even faster than my 5K iMac! Get this memory kit, along with an SSD, and your 2010 MBP will be around for many more years!

You have to remember that Im coming from a duo core 3200 circa 2005 but this processor is a billed- fast and stable. B & H, you are always trusted and reliable.

I just replaced my 2008 era MacBook battery with a NuPower replacement battery. Right out of the box the before fully discharging the new battery it indicated 65% charge level. This battery is lithium-Ion 54 watt hour, better that the original 45 watt hr unit. Easy old battery out new battery in. Initial charge cycle requires you to fully discharge the new batter before charging. The only drawback was it too so long to discharge the new battery before charging fully. B&H pricing for this battery was less than anyone I could find and shipping was free & on-time!

Moved up from a 6 core AMD to this, it seems to be more than 10 times faster. Coupled with M.2 SSD it boots from cold off in less than 60 seconds, 480i videos that took over 50 minutes to render on the old machine render in slightly over 5 minutes.

This charger is the perfect size for charging the Duo C batteries when traveling or on set. It weighs nothing and drops right in my bag. I have two of them and they are awesome!

We have several of the Watson Duo chargers and the affordability of the adapter plates makes this a very versatile and low cost charging system.
