Hi, Static electricity is the sworn enemy for Ram Chips.
If your tower is standing on the floor on carpet then place somthing non static under it. If you have you tower on a desk then you may have an earth problem and should take it to a technician asap.

I have a cc 500 bat push mower the battery charger was leftout on rain the light dont come on for charger is it fried also does it have a plug that i can plug extenstion cord in or do I n


The charger lead should have been connected to a Residual Current Device, or Earth Leakage Breaker that should have flipped the power off. There should be a reset button on the plug.

Charge the mower for 14 hours before initial use. Charge mower indoors in a dry area out of the weather. DO NOT charge in rain or wet locations. IMPORTANT: Use only the battery charger provided with this mower. Plug the battery charger into the battery first, and then into any standard 110/120 volt household electrical outlet. See Fig. 3-9 for B battery charging location. A C NOTE: If an extension cord is required, use one that is at least wire size 16 AWG. Connect the extension cord to charger before plugging extension cord into electrical outlet. NOTE: You may charge the battery with the battery removed from the mower. IMPORTANT: Always recharge battery fully. It takes 14 hours to recharge a completely discharged battery. A flashing light on the battery charger indicates the battery is less than 80 percent charged; a solid green light indicates the battery is 80 to 100 percent charged. A full charge will be achieved in less than 14 hours if the batteries were only partially discharged. NOTE: It is recommended that the mower be charged once every two months during storage. IMPORTANT: Always disconnect battery charger (or extension cord, if used) from the electrical outlet first, then disconnect battery charger from battery. NOTE: It is recommended that the mower be charged immediately after it has been discharged. Storing batteries in a discharged state could reduce future performance. WARNING: The battery contains corrosive fluid and toxic material - HANDLE WITH CARE. Keep away from children. Do not puncture, disassemble, mutilate, or incinerate. Explosive gases could be vented during charging or discharging. Use in a well ventilated area, away from sources of ignition.

Tip

Battrey types and maintanance


<span> <p>Nickel-Cadmium</b></i><br />This type of battery must be fully discharged and then fully recharged every few weeks. If you don't do this, it will quickly lose battery life due to what is known as the 'memory effect'. The memory effect means if you don't follow the above procedure, your battery will only charge up to the percentage of the last charge.<br /> <p>For instance, if you discharge it to 30 per cent, it will only charge up the remaining 70 per cent. Do this repeatedly, and the 30 per cent will become unusable, giving you an effective 70 per cent charge even though the indicator will still show a 100 per cent charge each time you charge it.<br /> <p>Nickel Metal Hydride</b></i><br />Ni-MH batteries are similar to Ni-Cd batteries, although they are less susceptible to the memory effect. They also have a higher capacity.<br /> <p>Lithium Ion</i></b><br />These are the latest type of batteries, and have no real problems as far as the memory effect is concerned. The problem with these is that they lose their effectiveness if overcharged or left for a long time with a full charge. Always discharge these batteries if you're going to be storing them away.<br /> <br /></span>

Does it hurt battery to keep plugged into electricity all the time?


If it is Lead Acid or Lion that is fine to float charge but not NiCad. The NiCad batteries have a memory effect and will quickly degrade if not discharged.

Ijustbought a newbattey for my acer aspire 6920 laptop. Iinstalled it and it said 61% available, I let it charge all night and all day untiljust now 7pm. and id still says 61% and charging . the old one...


First try a REFRESH by discharging it COMPLETELY than re-charging it COMPLETELY (do that 4-6 times) nice week end project ha!, than if it still won't charge completely ASK FOR A REPLACEMENT OR REFUND... (if it's new it should be under waranty)

Good luck!

How do i discharge a new camera battery sanyo vpc-t1284


hi anna ... you probably dont want to do that (discharge the battery) .. depending on the battery chemistry, you cant gain anything and can damage the battery ... for long term storage, lithium batteries like about 70% charge and dont like any complete discharge .. in fact better chargers will refuse to charge the Li battery once the cell voltage goes below a threshold .. when your lithium battery shows dead it is actually still higher than that minimum voltage.. once the cell is below that critical value then conductive bridges start to form inside the battery, that can cause battery overheating and possible explosion during subsequent charging .. so lithium batteries want to stay at least partially charged .. ... NiMH batteries can be fully discharged but that doesnt gain you anything .. they have no "memory effect" .. and deap cycling doesnt improve performance .. normal use cycling of a new battery may increase its capacity slightly as it "breaks in" but deap discharge is not needed or recommended .. for long term storage they want to be in an initial state of fully charged .... in NiCd there is thought to be a "memory effect" which is actually an overcharging effect ... those cells can sometimes benifit from a few deap cycles (conditioning) to erase the effects of over charging, but NiMH and lithium have mostly replaced NiCd in anything less than several years old (since Cd is toxic) .. ... there is only one case where lithium batteries are purposly discharged ... thats on some laptops or other equipment that use relitively large batteries ... but thats not for the battery its to reset the "power remaining meter" in the laptop .. that is a calculated value that tries to measure discharge time vs charge time to guess at what state the battery is in .. it can eventually become inaccurate due to accumulated errors .. discharging then charging the battery will reset that to a new starting point .. so purposly discharging LiON and NiMH batteries is not a good idea and doesn't .improve anything ... there are a lot of people that think it does but thats just habit left over from the NiCd days ... even some manufacturers of electronic stuff still believe that, but you can easily look at the battery manufacturers site to get their view .. you will find that the age old custom/habit of battery cycling is wrong unless you are still using the old NiCd cells ....

Aspire zg5 battery won't charge


Memory effect, also known as lazy battery effect or battery memory, is an effect observed in nickel cadmium rechargeable batteries that causes them to hold less charge. It describes one very specific situation in which certain NiCd batteries gradually lose their maximum energy capacity if they are repeatedly recharged after being only partially discharged. The battery appears to "remember" the smaller capacity.

This may be why.

New ram not speedy


well, the lowest speed of those rams will be effective for all rams. If you install same sized ram on 1st and the 3rd port, it should be run on dual channel mode and will be fastest possible. please try this if you have 4 ports.

Battery maintenance


you should charge fully then remove power once it is charged.
use it with battery till battery is discharged.

leaving it plugged in all the time will kill the battery.

thanks for rating.
