Q: I Attach the battery to the back of the DVD player, I plug the cord into the batteries charger port but the lit does not turn on. When I unplug it the next day. IT still is not even charged. Does anyone knowwat is wrong with it. Just an answer please, not people telling me to buy a new portable DVD player.: How old is the battery pack? If it is a year old (of fairly continual use), then it is shot. Rechargeable battery packs don't last forever. If the pack is new, then the charging circuit inside the DVD player is shot. There is one possibility, that the connection points from the battery to the player are oxidized. If you can get to the little metal points that make the connections from the battery pack to the player (on both the battery pack and the player); take a pencil eraser and rub the metal to shine it up. That might help. If not, the charging circuit is shot. Sorry. .

Q: Basically, my desire is to power a fan off of a battery pack, while also having a solar panel fueling the battery. It also needs to be small enough to carry with me. Is this possible? Where might I find such a battery pack? I wouldn't mind using rechargeable AAs as opposed to a single battery.: As kk says, charging systems (like in a car) are designed for exactly that. Lead-acid is kind of heavy to carry. Try something modern like lithium-iron or lithium-ion with a higher energy density (I don't know much about Li-Iron, but I just ordered one for my motorcycle that is a third the weight of lead-acid but with the same high current and longevity etc.)

Q: What almost all of the remote control cars, are using the battery pack, can not use the No. 5 battery?: To the young friends to play, such consumer groups are generally aware of the battery, so you can disassemble the battery.

Q: I am finally going to upgrade to a digital SLR soon and am trying to figure out how long these $250 power battery packs (that clip on to the bottom of the camera) last compared to a small $30-$60 battery. While there are reviews, this is the most important aspect of the item I cannot find. How long does this last and how much better is it than 1 or even 2 extra batteries?: you can ask for the after-sale center to learn about it or google it.it is a little difficult to say correctly,it all depend on the models.

Q: I have an old lawn tractor i want to get back up and running. I was wondering if i could start it with a homemade battery pack (made out of 8 AA batteries). PLEASE HELP ME!: Yea u can

Q: I have replaced the ni-cad cells in my 18V bosch drill with li-ion cells (respecting the voltage and wiring).Can I use the original ni-cad charger?The charger knew when to stop charging with the ni-cad battery, will it do the same now?Thank you.: If you can stop a 300 ft pound impact wrench it isn't worth owning unless there is a torque setting and you have it on the weakest setting. Regarding the batteries, tools are usually one or the other meaning that if it comes with NiCad or Li Ion there is no switching to the other or why would they produce two batts for the same device. If you HAVE a choice Li ion batts are very light in weight by comparison to 18V NiCads are. I have two cordless drills I use/used. One is an 18 volt DeWalt with NiCad and the other is Rigid with Li Ion, they are both the same relative age ( maybe 6 months between the two) . My DeWalt is still going strong 8 years later, but the Rigid with compact Li Ion batts are BOTH dead and gone: no recharging will kick them over. I called customer service to see if I could find out whether it was the charger or the batts. They weren't any help so I got another charger and the batts came up as defective. At $100 each I am in no hurry to replace them because the DeWalt is still going strong. So I am convinced Li Ion is one I personally will avoid going forward.

Q: a 9.6volt 1100mah battery does not hurt it at all. also current amperage affects rof and power too right?: If you put a 10.8v battery in there, you will wreck every internal gear that there is to wreck, that is way too strong for a stock gun, especially a clone brand. Stick with the 8.4v, or whatever battery came with it, otherwise your friend has just lost a large investment

Q: If I get the battery pack, will the batteries last a long time or do they finally wear out after so many recharges? Is it worth buying a battery charge pack?: It comes with a rechargable battery %. (a minimum of mine did). do not hassle touching directly to the battery life, it lasts long sufficient and in case you lose means then only hook it as plenty because of the fact the USB port (by potential of charging cable). What I do is only play wirelessly, then on the comparable time as i'm finished I turn off my xbox then twine up the controller and xbox expenses the controller till ultimately its thoroughly charged.

Q: I was wondering if xbox 360 controllers that come with a rechargeable battery pack have the same serial number as the one on the actual battery pack, because I think my little brother swapped my controller for his broken one but I can't really tell: simply put im afraid not sorry

Q: i put in the pack it came with, it charges and turns red on the bulb.but i just put in newly bought rechargeable energizers but the bulb doesnt turn red. is it charging.: it only charges xbox rechargeable batteries. not real batteries
