Q:Airsoft battery pack question.?/.?
Higher voltage will increase the rate of fire, but I wouldn't recommend it because most stock gears cannot handle that much stress. In other words, yes but you would have to put some very good internal upgrades into the gun, or else you could destroy the gun. And the battery cannot influence FPS of the gun, only rate of fire.
Q:Really old batteries left in battery pack?
If there is no sign of battery leakage or corrosion, you should be OK to use it.
Q:Why does my controller give me four flashing lights when i put in a nyko rechargable battery pack?
you need to sync it to the xbox by pushing the small button on the controller and the button above the power and hold them down
Q:Would a defective battery pack cause a laptop not to power on even when plugged in?
Unless the battery has physical damage to it then it can cause the computer not to turnbut in this case it sounds like your actual motherboard can be bad.viruses will only affect the computer once it gets past the HP splash screen, but if that HP logo doesn't come up, it sounds like it is a bad motherboardRecommend to take in to a local PC shop to have a look at it.
Q:How do you use the Wii battery pack?
Do you have rechargeable batteries or a Wii charger kit? Because you can't charge your Wii remotes with the standard equipment included with the Wii. You have to either - #1 - Put fresh batteries in the Wii - either new batteries, or buy rechargeable AA batteries with a charger. #2 - Buy a Wii remote charging station. This is probably the battery pack you are referring to. The battery pack is inserted in place of the AA batteries, then the whole remote is inserted in a charging dock to charge.
Q:Airsoft Battery Pack Help?
It depends on your hop-up and your mechbox, if you have like systema grade internals it will be fine but if you have a v1 or v2 mechbox it has the potential possibly to ruin it yes
Q:do you really have to initially charge a li ion battery pack for 8 hours?
No you dont, they dont wear out in the same way as other metal hydride batteries do when you dont totally discharge charge them.
Q:6 cell battery and 12 cell battery?
The capacity of a battery pack is measured in mAh so as you have mentioned a 4400 pack will last X minutes on a single charge. A battery pack of say 8800 mAh would last 2 x X minutes (approx) per single charge. The lifetime of each would be similar The physical size grows dependent on the number of cells as will the weight so more cells more capacity more weight. All cells are not created equal. A really cheap battery probably uses cheap poor quality cells, use a USA based supplier with a warranty worth the paper its written on and you should be just fine. Sony charge a lot more than these guys. Check the link for one such USA based company.
Q:Does it mean anything significant if the amount of water needed for four deep cell solar battery pack ----?
If you have batteries in parallel, check the wiring. There is a way to wire them diagonally so that they all have equal wire lengths and participate equally. In the worst case, if the 4 batteries are wired straight across in parallel, the one that is nearest to the load is doing all the work during discharge, and is the one charging up during the day. It doesn't seem like a length of fat wire should make much difference, but it does.
Q:Xbox 360 Rechargable Battery Pack Wire Green but not charged? HELP!?
I hope you bought warranty too, but it may be the wire, the 360, or the controller. Switch up the batteries and the cables and controllers and see if that works out. Or you can just go back to where you bought it and pray that they take it in. Go to the Xbox website, it may have some more info. Plug it into a computer? Buy a new controller Idk
