Question about Sharp EL-9600C Calculator

Short Battery Life

It seems like the battery life has become shorter now after I use my calculator for about 5 years. With fully charge batteries it could run at least 6 months, now it's about only 2 months; I use it as frequently as I used to. Is there anyway to fix it? Thanks.

How long does a battery last in a vehicle


This depends upon the quality of the car battery, and how you take care of it. If it is in a car and the car is driven daily, you should expect the battery will last 5-7 years.

If the car is not driven for extended periods of time, a battery tender should be placed on the battery, and failure to do this can ruin a battery. If it is a boat battery, during the off season the battery should be removed from the boat and a battery tender put on the battery.
If your battery has removeable caps on the top, make sure the battery is filled to the interal ring with distilled water. It is especially important to do this before charging a dead battery.

Do not store batteries directly on cement (place a piece of 2x4 under it). I know why, but batteries stored directly on the cement seem to die much faster and have a shorter overall life.

Motorola Fire XT (XT530) charging problem .


Motorola FIRE XT Tips for extending battery life
Back to Previous Page

Are there any tips on how to extend the battery life?
Things you should know about charging your battery.

New batteries are not fully charged. Plug the battery charger into your phone and an electrical outlet. Your phone might take several seconds to start charging the battery.
Tips:
  • It may take several charging cycles for your battery to reach optimum performance.
  • The battery charger shipped with this device is designed specifically for Motorola mobile phones. Other chargers might take longer to charge your battery, or cause your calls to fail during charging.
  • You can charge your phone via USB cable but this charging time will vary based on computer specifications.
Tips to extend battery life:
  • Select a shorter backlight duration
  • Lower the display brightness
  • Use the AC adapter to charge your phone whenever possible
  • Turn Bluetooth off when not in use
  • Turn Wi-Fi off when not in use
  • Close any third party applications running in the background
  • Playing music, videos and viewing images in your phone will affect your battery life
General Battery use & safety
  • Motorola recommends you always use Motorola-branded batteries and chargers. The warranty does not cover damage caused by non-Motorola batteries and/or chargers.

    Caution: Use of an unqualified battery or charger may present a risk of fire, explosion, leakage, or other hazard. Improper battery use, or use of a damaged battery, may result in a fire, explosion, or other hazard.
  • Your battery can be charged without it being fully depleted, and can be charged every day if desired.
  • Battery usage by children should be supervised.
  • Important: Motorola mobile devices are designed to work best with qualified batteries. If you see a message on your display such as Invalid Battery, Invalid Charger or Unable to Charge, take the following steps:
    • Remove the battery and inspect it to confirm that it bears a Motorola "Original Equipment" hologram;
    • If there is no hologram, the battery is not a qualified battery
    • If there is a hologram, replace the battery and retry charging it
    • If the message remains, contact a Motorola Authorized Service Center
  • New batteries or batteries stored for a long time may take more time to charge.
  • Charging precautions: When charging your battery, keep it near room temperature. Never expose batteries to temperatures below 0°C (32°F) or above 45°C (113°F) when charging. Always take your mobile device with you when you leave your vehicle
  • When storing your battery, keep it in a cool, dry place.
  • It is normal over time for battery life to decrease, and for the battery to exhibit shorter runtime between charges or require more frequent or longer charging times. Motorola batteries are designed to last between 350-700 charge/discharge cycles at room temperature. This amounts to approximately a year to a year and a half of battery use for most people.
  • Avoid damage to battery and mobile device. Do not disassemble, open, crush, bend, deform, puncture, shred, or submerge the battery or mobile device. Avoid dropping the battery or mobile device, especially on a hard surface. If your battery or mobile device has been subjected to such damage, take it to a local service center before using. Do not attempt to dry it with an appliance or heat source, such as a hair dryer or microwave oven.
  • Use care when handling a charged battery-particularly when placing it inside a pocket, purse, or other container with metal objects. Contact with metal objects (such as jewelry, keys, beaded chains) could complete an electrical circuit (short circuit), causing the battery to become very hot, which could cause damage or injury.

We at CAAP Davao Philippines have a MGE Galaxy 3000 10KVa UPS with serial no. 13299-4. It was installed last 2003. We had three times replaced its batteries over the period of years, the latest was 2008....


On the Galaxy display you could see what is the remaining battery life time as calculated by the software. Normally after you replaced the batteries you are supposed to reset this counter using specific software by the manufacturer. According to your information you have replaced the batteries 3 times in 5 years period. This is not normal. Nevertheless since the last replacement in 2008 it appears that the battery are now reaching the end life, which is generally 3-5 years life expectancy.

I would review the following of the assumption that the UPS is fully operational and the charging system is working.

1. Do a load test or a battery impedance test to verify the batteries are good
2. I would look at the battery life time specification, whether it is 3-5 years, 5-7 years ect.
3. Check the room temperature, every 10 degrees Celcius above 25 deg reduces battery life time by half
4. Check the number of power failures/ duration of these power failures and if possible what load were on the UPS at the time of the power failures.
I hope this will help. If all verifications are to specifications, then most likely it is a software problem

Rechargeable battery cannot be charged despite continous plug in of AC cord of charger


Battery is probably dead. Will need to purchase new one, not repairable. When replacing, do not buy "new" battery that has been sitting around on a shelf for several years. Will have much shorter life. Insist on battery that has been made within the last year, maybe 18 months at most. Expect to pay $50 to $125. To increase battery life, try not the let them fully discharge when using. Most recommendations are keeping them above 10% charge.

I'm not sure of your charging regiem but it is possible that you hav not let the batteries become disscharged before they back on the charger, short cycling particular batteries gives them a memory and reduces their life significantly. Most rechargeable batteries have a life of so many cycles, just say its 100 cycles. If you put on charge when battery is only down to 80% and charge it up this counts as 1 cycle. Therefore your battery life would be reduced to 20% of what its capable of. This is only true if short cycling the chargeing of the battery is frequent. Not knowing exactly what your charging habits are or the age of them makes it a guess from me. It otherwise might be a fault in your charging circuit which would require specialist diagnosis.

Short battery life


$orry, theres no fix to this, after a while batterys begin to die and the life becomes shorter. this could be due to leaving it on charge all day and night and not letting it frequently loose and gain charge again. even my laptop battery has began to lose its battery length - but ive had my battery for a long time. purchase a new battery and try to keep from leaving the A/C adapter in over night. you should notice alot longer battery length after that. rate me :)

Short battery life


Try running the battery down completely (0% so it turns off itself), and charging whilst the phone is completely off (I'd suggest leaving it overnight). Repeat this once or twice, then see if your battery life has improved. Also ensure that you havent left anything on that could be eating your battery up i.e. bluetooth, and contact your supplier if the problem persists, as you should be covered.
