No - you can plug them in any time to bring them back up to 100% similar to a cell phone. In fact if you run the battery to 0%, it will take longer.

How is a battery in a home security system recharged?

Normally you need to replace the battery periodically if your system has one. Some old designs of installed systems (not self installed wireless types) are hard wired to a power source and don't need batteries but nowadays most systems have built-in stand by batteries. On security systems that have a stand by battery, that kicks in on power failures, the battery is charged by the motherboard of the system. There is an on board charger where the battery connects to the board. After a power failure, when the power returns, a sensing circuit detects that the battery is low. It automatically starts charging the battery back up to its fully charged state. These batteries usually last about 10 years before they need replacing.


Is it actually good to use rechargeable batteries like on a phone or ipod until they die and then recharge them after they die or is it better to recharge them before they die?

it is beter to not let the batterie die.. just charge it once it starts showin low battery....you can't get rechargeable batteries for ipod if u had one u would know that


Will a radio still work after battery is disconnected on a 2008 chev impala then re- connected?

it should work fine unless you have it unplugged for too long. i have replaced batteries in these cars before and did not have to reset the radio


Why is my phone is battery is dying while it is on the charger?

It may be that your battery is old. Rechargeable batteries work best when they're allowed to completely 'die' before recharging. Most people don't allow that to happen (me included !) - and thus the battery's life is shortened.


Is Gackt sick?

Officially, he hasn't said anything about being sick, however while watching many videos of his tours and such, you can often see him passing out and his bodyguards dragging his unconscious body off the stage. :( He's probably just exhausted, however whether he is sick or not is unknown.

Are there any radio control cars that come with rechargable batteries?

Most high end radio control cars come with recharable batteries. You can also purchase extra rechargable batteries so you don't have to wait for the battery to charge before you use the car.


What does it mean to precondition batteries?

By fully charging and fully discharging some batteries the expected charge time can be increased. Some rechargable batteries will last longer per charge if they are fully discharged before you recharge them again. Recharging batteries before they are fully discharged may cause a battery memory effect that will allow the battery to run for a shorter period between recharges.


How long do batteries last in wireless security cameras?

Depending on the batteries, would allow your wireless surveillance cameras to last a longer period of time. this system in the llnk below for example lasts up to 350 minutes. http://www.cvsecuritycam.com/product/GX301-012. Its really up to the brand of the cameras, some lasts more than others.


Should you let your computer battery die before recharging?

No, completely discharging a lithium battery will damage it significantly reducing its ability to hold charge. However a lithium battery that is discharged to just a few percent of completely discharged before being recharged will get more successful recharge cycles than one that is recharged much earlier. Its a somewhat tricky balancing act and I have destroyed a few batteries myself by not stopping the discharge soon enough.


How long do rechargeable batteries last before they must be replaced?

Under normal circumstances and use Rechargeable batteries generally last approximately 500-800 charge-discharge cycles. If you are an average user of the rechargable battery that would be equal to about 3 years.


Do you need to let a laptop battery run out?

It depends on the type of battery you have in your laptop.NiCd (Nickel Cadmium) batteries have a sort of memory effect. It is a good idea to cycle (Discharge fully) these kind of batteries as this ensures maximum capacity for longer.NiMhd (Nickel Metal Hydride) does not have this memory effect. They should not need to be discharged fully before being recharged.Memory effect is:The battery "remembers" after a few times of being recharged, when it was recharged. The capacity will then start to drop drastically and begs for a recharge when it reaches the point of where it normally have been recharged before.Example:A battery (NiCd) being at 50% and then recharged will after a few times drop the voltage at 50%. This giving the impression that it is "empty" where it is not really so.Note:The memory effect can be cancelled with a couple of deep discharge and full charge again. The battery is then -revived- brought back to capacity again.


What fuel was used in torches before batteries?

Sony Walkman will not take a charge?

Rechargeable batteries have a "life cycle". Ni-Cads can only be recharged so many times before they just completely give up. Lithium have a longer life, but eventually they too will reach their life maximum and no longer accept or be able to hold a charge. Try replacing the batteries and see if that helps the situation. No batteries to replace. Its like an ipod. Sony just sold a bunch of crap units to us all.

How many times can a Cellphone or Laptop battery be recharged before its lifetime is reduced significantly?

Modern lithium ion batteries seem to have a life span of about 300 charges before their per-charge lifetime starts falling off. The manufacturers claim 500 cycles, but that is in optimum conditions of use and charging, conditions that are rarely met in real life.


How can you recharge nonrecharge AAA batteries?

Depends a bit on who you ask. Some - manufacturers of special chargers - will say that you can, at least a few times, if you use their chargers. OTOH, according to the manufacturers of "real" rechargeable batteries, theirs are the only ones that can be recharged. People who have tried the special chargers, and charging supposedly non rechargeable batteries will usually tell you that it does work, but that you don't get much capacity, and you only get a few charges before they're entirely useless. Oh, and sometimes they leak/burst. And don't try charging non-rechargeable batteries in a regular charger. That will almost always lead to the batteries leaking or bursting.
