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:What is the charge time of a NiCd 9.6v 400mah battery pack?
the rate is normally 1/C - the inverse of the current capacity. 1 hour only if you have a Smart Charger and it can sense the heat generated by charging the battery. I recharge my 9.6v/4000mAh pack in 15 minutes, but I have a battery that is MADE for hot charges and my charger is made to push that much current into the battery.
Q:How long to charge first-time DSLR battery pack before using it?
It isn't an issue with modern technology. Don't overcharge, like leaving it overnight. Run the charge down to the last bar on the display and recharge until the light on the charger say's it's finished. Most chargers are on a timer anyway and you can't overcharge as the charger cuts out after a certain time. New battery? Pop it in and use it straight away. Current thinking says top up charging, where you charge it any time even if it's not flat, is perfectly fine for a modern battery. Older advice from years ago is outdated.
Q:Is there an extensive battery pack for the Nintendo 3DS that fits inside the back?
Im sorry there is not one but with the new chargiing base you can play at the same time you charge it!!!!!
Q:Run 1.5 volt battery pack from wall outlet?
I assume there's no external power connector on your drums (bad design in my opinion). There are some products in the market that do what you say, but they are specially made for specific devices such as professional flashes and cameras. The problem is that each battery compartment is different, and you also have a problem with the door. I think you're way better off by getting a good set of rechargeable batteries and a wall charger. Buy brand (Energizer, Sanyo, etc), you'll save money in the long run.
Q:Question about battery pack for telephone (cordless)?
Look at the voltage of the battery pack, it's probably 3.7. I've never heard of a phone burning up unless it takes a lightning hit. The plastic should stay on, it's protection from the battery leaking. You won't start a fire.
Q:Are the xbox 360 controller batteries rechargable?
No, the double A batteries are not rechargable. You have to purchase a rechargable battery pack from the store. I definitely recommend them, and I'd have two batteries so that when one dies you have another on the charger.
Q:I want to get the rechargeable battery pack for my xbox 360 controller. Help?
There are a few choices. You can get the Play and Charge kit that comes with a battery pack and a charging cable for $20 so you can charge the pack while you play. There's the Quick Charge which comes with 2 packs and a charge stand that plugs into a wall socket. This is good if you use more than one controller at a time. Also, there's the Nyko charging base which charges the packs while they're in the controllers. You can also buy extra packs at any store that sells 360 stuff (Walmart, Gamestop, etc.). I like the Play and Charge because it's cheap and dependable.
Q:Is there a way to solder stranded wire to batteries, to make cells into a battery pack having more voltage?
yes tin the wire solder it to the batteries, take the - side and solder it to the Next bat on the plus side , then + to - then - to + called in series 2- 1.5 bat wired like this will give you 3 volts
Q:A problem with the battery pack on-line balanced charging.
Dynamic deviation, that is, the battery is running in the state of charge should not exceed 50mv.
