Amp-Hours Remaining Method—The best way to accurately measure Battery State of Charge is to continuously monitor voltage, amperage, and ampere hours remaining. This is a complex calculation of the energy available, energy consumed, and the energy returned to the battery in charging.
1) Don`t charge until you`re down to 20 percent

It`s typically between 300 and 1,000. So here`s a handy rule: Don`t start charging until your battery reaches about 20 percent — and try to stop when you get to about 80 percent. This will make sure you maximize each cycle while keeping the battery free of stress.

Maintenance chargers can be left connected to the battery indefinitely without risk of damage to the battery.
A battery cannot be overcharged.

There`s no danger of overcharging a battery if you leave it plugged in all the time, even 24/7. As soon as it hits 100 percent, it will cease charging and won`t start again until the voltage falls below a certain level.

A fully charged 12 volt battery should read at 12.6 volts on the multimeter. If the reading is lower than this, you`ll want to charge your battery with either a battery charger or by taking your car for a drive.
To find battery lifetime, divide the battery capacity by the average device current consumption over time. You can then break it down into where: The average is the sum of the amount of current consumed when collecting data, scaled by the ratio of time that the device is collecting data.
Battery Charging Chemistry

Charging a battery reverses the chemical process that occurred during discharge. The sulphate and hydrogen ions basically switch places. The electrical energy used to charge a battery is converted back to chemical energy and stored inside the battery.

Even though there is no risk of overcharging with the use of a high quality charger, the battery should not remain connected to the charger for more than 24 hours. A full charge is usually achieved by charging overnight.
Put simply, you can safely charge your devices overnight without having to worry about damaging their internals. Modern electronics automatically stop pulling current once their batteries reach 100% charge.
Unfortunately, leaving your phone charging for hours at a time while you sleep isn`t great for your battery and could cause its performance to decline before you`re ready to trade in your phone. Discover why charging your phone overnight is bad, and how often you should be charging your phone instead.
This Type-C Smart Power Off Charging Cable is perfect for you. It will charge your phone to 100% and, once it reaches full, it will stop charging to prevent overcharging your device.
The 40-80 rule for lithium-ion batteries is a recommended guideline to extend the life of the battery. The rule suggests that you should charge your lithium-ion battery to a maximum of 80% and discharge it to a minimum of 40% to keep it in good condition.
Fully-charged, most car batteries will measure at least 12.6 volts (~13.0-13.2V for OPTIMA YELLOWTOPs), but low voltage doesn`t necessarily equal a bad battery. Modern cars are very demanding from an electrical perspective, even when they`re not being used.
If kept in a charged state when unused, the common lifespan of a 12-volt Gel or AGM battery is up to six years. After five or six years of float voltage at an average ambient temperature of 25 ºC, the battery still retains 80 % of its original capacity.
There are many variables that come into play when figuring out a battery`s lifespan. Some batteries, you buy and continue working for 10 or more years without issue. Sometimes, though, you install a battery and it gives up after only a couple of years.
Life Expectancy

Generally, electric vehicle batteries last 10-20 years, but some factors may reduce their lifespan.

“How long will a 100Ah battery last?” A 100Ah battery can last anywhere from 120 hours (running a 10W appliance) to 36 minutes (running a 2,000W appliance).
A good alternator should maintain battery voltage between 13.9 and 14.8 volts (14.2 is optimum). Even worst-case, with all accessories turned on, there should be at least 13 volts at the battery.
The safest amp to charge car batteries is from 4 to 7.5 amps. Charging within this range ensures the vehicle battery won`t overcharge, overheat, or be damaged in the process. Yes, you can safely charge a minimum voltage 12-volt battery with this amp rating, though it will be pretty slow.
The three stages or steps in lead/acid battery charging are bulk, absorption, and float. Qualification, or equalization are sometimes considered another stage. A 2 stage unit will have bulk and float stages.
Remove The Charger Once Charging Is Complete

To safely remove the charger, make sure to power if off before touching any of the other controls on the unit. Only after the charger has been shut off is it safe to remove the cables. Once powered down, remove the positive cable first, followed by the negative.

While fast charging can increase the rate at which your battery loses capacity, its actual impact is only about 0.1 percent more capacity lost than without using fast charging.
Don`t overdo it.

Overcharging occurs when the device or battery is plugged into a charger after full charge has been reached and may reduce battery life.

Dead battery? After sitting for 6 months w/o using, the battery was dead, I re-charged it and it would not hold the charge. The low battery light does not come on, after charging. If that is the problem, are these available for purchase to replace it and where can I buy one.
ANSWER : The battery is a commonly available 6 volt 4.5 ah sealed lead battery. Interstate has them and many other suppliers. I think same battery used some security systems…

Every time I replace the 4 AA batteries all camera
ANSWER : There is an internal battery back up for storing settings. It’s soldered to the main board and I don’t think it’s a rechargeable battery judging by the amount of people who have owned these cameras who have encountered the same problem.
It’s a watch type battery and these things do go flat after a few years and unless you know the type and voltage only fuji service centres can replace.
It won’t affect the camera’s performance it’s just a pain having to set up each time you change the batteries.

The control screen operates by a battery which is charged by cycling. We were in a car accident and it was unused long enough to run down the battery. When this happened before, we cycled till it was charged and then it worked. Now though, it is stuck at a level that we can hardly peddle at–not long enough to charge the battery. Any solution?
ANSWER : Hello.

You may need to pull the battery out and take it to a re-conditioner. In Australia a company called battery world can test the battery, re-condition or replace if needed.
if there is a way of using a external charger on it this may give you enough power to adjust the pedal resistance, be sure to disconnect the battery from the bike before charging and use the correct type of charger for that batteries voltage and chemistry
You can try manually releasing the pedal pressure by removing the wheel and releasing the resistance wheel or belt. With out a model type I do not know exactly how to do this, although it is fairly easy to see when the main wheel is off the bike.

I hope this points you in the right direction.

SENSEI MP3 i have a sensei 4gb mp3 player.When i plug it to my comp to charge it a battery appears.But its not showing any progress.How do i know if its charging or not.What color is the battery icon when it is fully charged
ANSWER : I could see the progress in the battery down right corner. If entire battery becomes black then it is full charged. However I have a problem of the charge getting discharged very fast i.e., when the player is NOT powered OFF.
