Macbook Cold Battery Not Charging

I needed to get basic power for lights into a shed that had no electrical hookup available. I have tried many battery powered lights, that just didn't cut it. They would die or were just not bright enough. I decided to try a Delta 2 and 2-100 watt solar panels to recharge the battery. I was only able to mount the panels on the east slope of the roof, but it has held the charge. I am in Ohio where it gets too cold and keeps the battery from charging when it gets too cold, so we have had several days where we weren't charging because the shed was too cold. I still have not run out of power for the 100' ten light strand I hung up. This setup is an expensive fix, but it has proved itself to work even through our cold, gray Ohio winter.

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!

Great battery when you must get the shot regardless how cold or how hot it is.

I am very impressed with the fast charging Hasselblad Battery Charging Hub. I always take a spare battery with me and knowing both are fully charged is one less thing to have to consider before the shoot.

Charging the camera's battery is a must if you want to take pictures!

Long lasting battery in the market for cold weather.

Great for charging more than one battery at a time

Necessary when charging the battery for BM6K Pro.

This battery had directions of charging with it, now we won't fry it!
