Batteries

In general, no. The charger is designed for a specific battery profile, and it might not be able to properly charge and/or monitor the amount of charge if you put in a different battery.

A dry-charged battery is a conventional non-sealed wet-cell battery (this is almost always a rechargeable type). Normally, this battery type is wet-charged, meaning that the battery is filled with electrolyte at the factory, charged, and then shipped with the electrolyte in the battery.

However, since the battery is not sealed, the electrolyte (either a strong acid or alkali) can spill out, which can be both a health and environmental hazard. The battery will also self-discharge at its normal rate during shipment and storage.

Dry-charging is a way to minimize these problems. Like a wet-charged battery, a dry-charged battery is filled with electrolyte at the factory and charged. However, the electrolyte is then removed from the battery. The battery is then washed out, dried out, and sealed. The battery may also be filled with an inert gas to minimize reaction of any remaining electrolyte, as in the U.S. military BB-451/U silver-zinc battery, which used a very strong alkaline electrolyte (40% potassium hydroxide).

The sealed battery is shipped and stored separately from the electrolyte. Because the electrolyte is in a sealed container, chances of spillage are reduced. The sealed battery will also self-discharge at a lower rate than usual, so it should still have useful charge up to 18 months after manufacture if stored below +90 degrees Fahrenheit (+32 degrees Celsius).

When the battery is needed, the electrolyte is CAREFULLY added back to the battery (eye protection and gloves must be worn and other precautions taken). The battery must be allowed to sit for some time afterwards so the electrolyte can soak around and through the battery's internal structures. The electrolyte temperature will rise and its specific gravity (SG) will drop during the soak. The manufacturer may recommend that the SG be measured after the soak time, and the measured value will have to be corrected for any difference between the actual electrolyte temperature and the temperature at which the reference SG was measured.

After the soak time, a (very rare) nonrechargeable dry-charged battery is ready for use, and some rechargeable dry-charged batteries may also be ready for use (like the BB-451/U). However, dry-charged lead-acid batteries will almost always need a low top-off or trickle charge. Rolls Batteries prescribes 5% of the 8-hour or 20-hour charge rate, to be reduced if the electrolyte becomes too warm or too much gas bubbles out of it. If the electrolyte in a rechargeable battery becomes too warm before charging, the battery will first have to be cooled down or allowed to cool naturally.

Because you really don't want to short out the circuit through your jewelry.

I was once working with a six volt lantern battery and my screwdriver slipped, briefly coming into contact with both poles of the battery. There was a brilliant white flare and, in the fraction of a second that the screwdriver was touching both poles, the arc melted halfway through the shaft. In fairness, this was a small screwdriver, but still I'm extremely glad this didn't happen to something I was actually wearing at the time.

it is a 3.75 volt cylinder shape flat end rechargeable lithium battery about 18mm diameter (first part of 18350) and 35 mm long (next part of 18350).

Depends on the current draw of what you hook it up to. At a draw of 7 amps (80 watts)

it'll last for one hour. At a draw of 1 amp(12 watts) it'll last for 7 hours, ASO.

Storage cell

You will die.

the positive piece on the first battery is connected to the negative piece on the next battery in the series and the negative pole from the first one is the negative you connect to the device you are powering and the positive pole on the very last battery in this series is the one you connect to the positive terminal on your device.

The electrons from the battery go through the wiring to the bulb. Inside the bulb, they heat a tungsten wire so hot that it glows, giving off light.

CR2032 batteries are a small flat battery that is used in a variety of devices. Blood sugar monitors, watches, and calculators all require the CR2032 battery. The average lifespan of one of these batteries is one year; however, they have been known to run up to five years. The lifespan largely depends on the amount of usage required by the unit. Of all the watch batteries, the CR2032 is arguably the most common.

Yes - so long as it's (a) physically identical in sizeand (b) the same voltage as the one it's replacing. The mAh number is the capacity of the battery - the 5200 mAh one will simply take slightly longer to charge than the 4400 mAh. I replaced the 950 mAh battery in my phone with an 1100 mAh one over two years ago - and it's never given me any problems. It just takes about 10 minutes longer to charge from completely flat.

The phone will go flat quickly. When charged it'll never switch from "charging" to "charged".

Or it'll say that charging is complete real fast, even when starting from a flat battery.

No reason why not. So long as the physical size of the battery matches, and the voltage it delivers is the same - you should be able to replace it with the higher mAh battery.

There are multiple centers specifically opened for the disposal of batteries. It is allowed in every state, although in California there are some extra regulations, which allow you to recycle more types of batteries. Good places to dispose them are The Home Depot, Best Buy and Wal-Mart.

For the most common battery chemistry, 3 cells of 1.5 volt each.

It has a big line and it also has a bold, small line.

The battery lead that is not the earthed lead should be removed first. If the negative lead goes to ground then first remove positive and vice versa.

This is true also for any non vehicular electrical device although the earthed lead is less easy to find but is almost always negative.

If it's the guess watch with the 6-notches on the back, try using a scissor where the tips fit into two of the notches opposite each other. Be careful and twist the lid counter-clockwise. I did it with my guess waterpro watch and it's a great method where you don't have to go to a repair place to replace the battery. Save your money.
