- Q: First off, I hope I am in the right place to ask this question, I don't really know where to go for help for this.To start, I am trying to make a portable battery to charge USB devices. So a 5 volt output. I am trying to do it cheaply, under 20 bucks. I have a bunch of laptop batteries laying around and no laptops to use them in. The one I am looking at using is a toshiba PA3383U-1BRS, It is a 14.8v 6450mAh battery. the cells inside are 12 of these -- SF US18650GR. I want to know how or if I can re arrange the cells to get the most battery life out of it. I dont know how it would be charged, what protection/charging circuts would be needed or anything like that. I know next to nothing about how this all works but my common sense says that it would be better to get the output of the pack as close to 5v as possible before doing anything with voltage regulators, to keep it efficient. Let me know what I have to do/ what I cant do/ why I am wrong/ if you need more info etc. thanks a ton guys!
- To make 5 volts battery pack,take 4 piece small cells out from Toshiba 14.4V battery pack. You need to know which cell is still good. Put 4 cells in series shall do.
- Q: I ordered a pair of Astro A40 Wireless headphones. After they shipped I did some research and found out that they come with 3 standard AAA batteries that you put into the transmitter. They do have an option, however, for a rechargeable battery pack that can go in place of the AAA batteries (they sit in a battery holder that is then removeable). This pack is then charged inside the transmitter via USB cable. So being the penny pincher I am, I was wondering if I went out and bought 3 rechargeable AAA batteries and put them inside the transmitter, would they safely and correctly charge inside the transmitter in the same fashion as if it was the custom battery pack?Hopefully I was clear enough Any answers are appreciated! :)
- It might work, if the batteries are of the same chemistry as their batteries, and the holder is not special, which has special contacts or a switch closure. I would probably do it because I know what I am doing. I have taken cells from older cell-phone packs, and used them in a regular cell charger, and as regular cells in things, so it stands to reason it can go the other way.
- Q: Hello everyone, i was just wondering if i should buy this battery pack for my canon G9, the link for it is below:
- at amazon see if they have the lenmar brand for your camera I use that brand for my canon cameras and I bought them at amazon
- Q: i recently bought a canon fs100. and i wanna know if its okay to charge it even if its battery's not drained yet.
- Almost every rechargeable battery sold now is memory free. Charge your battery anytime, but don't leave it on the charger forever. Once it is charged, take it out of the charger or camera and store it in a dry safe place where it wont be knocked over to fall and break or be internally damaged upon landing. This may cause the battery to leak, and if it leaks while in the charger or camera, you may also lose an expensive camera or charger.
- Q: I have an older gem from 2003. The gel battery pack is too far drained to be recharged. If I call for a repair, they'll charge $225. Is this something I can do and with what tools? Thanks.(More info, 10 points.)
- The Gem uses 12 V deep cycle Trojan batteries wired up to provide 48 V . That means there are four of these batteries in series, more may be in parallel with these four but basically chances are only one of these batteries has failed. If you run a voltmeter across each battery, you should be able to identify the bad one fairly quickly, then it's just a matter of replacing that 12 V battery with a 12 V lead acid, AGM, or gel battery with the same size, terminals and capacity. The capacities ranges from 130 AH to 150 AH. An actual new Trojan battery would run about $190 (without a rebate for the old one and you can usually get a rebate) but chances are you could get a used one for less or some other lead acid battery with similar dimensions (roughly 14 x 7 x 11 ) and capacity ratings for less. Gel and AGM batteries are sealed but if you were willing to break the seal (dangerous as it contains hydrochloric acid), it would be possible to drain the acid, clean the mats, file down the plates, reassemble and add new acid to rebuild the battery. You may be able to find someone who does this and can sell you a reconditioned battery. Once you isolate the failed battery with a voltmeter, you could try charging it individually (sometimes a battery won't charge because other batteries in the series are already at full charge). You may even be able to bring a dead battery back to life by trickle charging and pulsing reverse polarity through it to break up the sulfate buildup on the plates. It's probably a good idea to periodically break up the battery pack and charge each battery separately to try and get as much charge into each one as possible. Chances are, the tools needed would be the same tools you would need to change out a car battery except that these batteries are heavier.
- Q: i spent so much buying rechargeable batteries for my player (4 pcs size AA). i cannot wait charging the batteries especially when i am on the go. i want a portable battery pack which i can take along when i go out. my player requires only 9v. playing video at long hours easily consumes the charge that's why i am looking for a battery pack which lasts longer.
- Battery packs are usually built in but an adapter to work on 120vac or 12vdc just plug in. You can DIY a battery pack to work at the adapter plug in.
- Q: I heard that there's an official Microsoft rechargeable battery pack that can be used with the Play and Charge Kit, and another one that's only a shell battery compartment that you attach to your controller and use normal disposable batteries for it. Which kind of battery pack is included when you buy an Xbox 360 Wireless Controller?
- The Rechargeable Battery Pack for the Xbox 360 controller contains two AA nickel metal hydride (NiMH) batteries inside a sealed casing, with a custom connector on the rear to allow charging through the Xbox 360 controller itself. If you need more information you can visit the following link
- Q: i have a spare battery pack and one of my controllers is broken, so buying the wired controller and putting a battery pack in it would be a cheaper solution (if it can be done)
- okorder
- Q: I want to power six devices which take one CR2032 (or 2 CR2016) with either one 18V battery pack or with two 9V batteries. Is it possible and if so how?
- Not okorder
- Q: 1.5v 1 battery 4 how to splice into a battery pack?
- First calculate the power and current through this resistor to derive the actual power, and then buy a power factor of 1 ohm higher than the actual power you calculate.
