Q:I just bought a Canon 50D, and i've heard from many people on how long the first charge should be. I'm confused but do not want to try and end up spoiling the battery. Can somebody advise how long should the battery be charged for the first time?I've heard people telling me 2hrs is enough but some tell me its too short and you'll undercharge the battery.Others say you have to charge for at least 12 hours. Will this overcharge the battery and shorten its lifespan?Please help me!

Canon Li-ion Battery Pack

Q:I have an e-bike using a 36 volt/9 amp battery pack.I want to up grade the compacity to 48 volt/9 amp battery pack. Can I use the same smart charger for the upgrade?

Usually there isn't reverse power protection with chargers because putting a diode between the charger and the batteries is the same as there not being a connection. That means if you put larger batteries in the charger it is like putting larger batteries in a portable radio or boom box. The charger might be able to handle it for awhile but I think the 12 volt difference would be too much.

Q:I have two battery packs for my 18v Dewalt drill and neither will take a charge. Is there a way to revive them so they will charge up?

No simple way as rechargeable batteries have a limited number o fcharge and discharge cycle, around 200 to 500. After that, it's dead and will need a new one.

Q:i hvae att and i want to put my sim cardinto my dad's iPhone. but neither of us know how to open upto the battery sim card area. does anyone know how?i've asked like all my friends and everyone haha help!

Use a paper clip on that small hole on the top of the iPhone. The SIM card drawer will slide open from there. You can't access the battery at all.

Q:Can you use a battery grip with just one battery pack or do you actually need 2?

What does the manual say? Have you tried using the battery grip with just one battery pack? If yes, why do you think it didn't work?

Q:These battery packs are the same physical Size.- They both use the same charger.- I don't want to damage my drill by using the higher voltage pack.

It will work but the cordless drill does have a limit on the ampage that it allows to go through it. Just check the amps in the users manual, you should be ok, it is not that big of a jump. I would probably NOT do it from a 14 up to a 19 but I think an 18 to a 19 would be just fine. double check your users manual. good luck.

Q:i put a 36 volt battery pack on my 24 volt razor pocket rocket, will this make it faster or just brake it? i also have a 36 volt charger that fits the bike that i got from my friend that i would use, i didnt charge the bike and try it yet bc idk if it will work. please tell me if this would work, thnks.

it will be faster, then it will be dead. Unless your lucky.
