[No title]   (Site not responding. Last check: 2007-10-15) Trickle charging is normally done at a rate of about C/40 or one fortieth the capacity. That is for a 1000 mah pack the trickle charge rate would be at 25 ma There has been a lot of discussion on whether you should charge a receiver or transmitter nicd pack with a trickle charge or not. The reason is because the charger is probably charging at a rate of 50 mA (C/10 for a 500 mah pack) When trying to use that same charger on a 1000 mah pack you are charging at C/20 which is close to trickle charging. home.att.net /~richard.g.scott/page24.html   (686 words)

Electrochemistry Dictionary For a rechargeable battery: the fraction, usually expressed as a percentage, of the electrical charge stored in a battery by charging that is recoverable during discharging. In the charged state, the active material of the positive electrode is nickel oxide while that of the negative electrode is metallic iron, with a basic (potassium hydroxide) electrolyte. The structure of charge accumulation and charge separation that always occurs at the interface when an electrode is immersed into an electrolyte solution. electrochem.cwru.edu /ed/dict.htm   (11210 words)

Battery Chargers and Charging Methods Fast charging forces up the rate of chemical reaction in the cell (as does fast discharging) and it may be necessary to allow "rest periods" during the charging process for the chemical actions to propagate throughout the bulk of the chemical mass in the cell and to stabilise at progressive levels of charge. During the charging process, short rest periods of 20 to 30 milliseconds, between pulses allow the chemical actions in the battery to stabilise by equalising the reaction throughout the bulk of the electrode before recommencing the charge. Trickle charge Trickle charging is designed to compensate for the self discharge of the battery. www.mpoweruk.com /chargers.htm   (4323 words)

Patent 4742289: Method for the cyclical trickle charging of a chargeable battery intended for emergency operation The present invention relates to a method for the cyclical trickle charging of a chargeable battery intended for emergency operation, in which case the charging voltage used is the output voltage from a source of d.c. The battery is trickle charged in order to keep it at a high level of readiness for emergency operation, and this takes place in a conventional manner by connecting a continuous charging voltage across the battery, by means of which the battery voltage is made to stay at the specified value. During charging stage 6 charging of the battery will take place at an increased charging voltage for an interval of time d which is of the same order of magnitude as, but longer than the interval of time a. www.freepatentsonline.com /4742289.html   (2191 words)

Vencon Technologies - Battery testers, Battery analyzers, Battery chargers, Battery conditioners Trickle charging is one way to do that, charge replacement the other. Since I doubt a trickle charger came with your battery, we will need to be a bit more inventive if we want to trickle charge our batteries (or you can go out and buy a commercial trickle charger). Also, even though your batteries are on trickle charge, you still need to do a full discharge test every month or so to ensure their condition. www.vencon.com /index.php?page=support_art2   (1675 words)

Trickle Charging A trickle charge is a continuous constant-current charge at a low (about C/100) rate which is used to maintain the battery in a fully charged condition. charging is used to recharge a battery for losses from self-discharge as well as to www.tpub.com /content/doe/hdbk1084/css/hdbk1084_43.htm   (352 words)

Great Hobbies - Tech Talk Charging Systems Charging at a low enough current such that the charger may be left on the battery indefinitely is called trickle charging. Trickle chargers are generally used in conjunction with either a system charger or fast/peak charger to maintain the battery after a normal charge and may even come as part of a more sophisticated charging system circuitry. Timed charging is a method of fast charging where the charger is on a mechanical timer so that once the timer runs out, the charge is shut off. www.greathobbies.com /document/tech_charge.html   (1121 words)

Patent 4853607: Non-isolated thermally responsive battery charger The trickle charge path is provided by an impedance shunting the thermostat and is operative as a current path when the thermostat is in its open condition. The trickle charge path can be a resistor where the thermostat is in the DC part of the charger circuit or a capacitor where the thermostat is in the AC part of the charge circuit. In general, the `trickle` current level provided through the resistor R.sub.1 is sufficient to prevent self-discharge of the battery B, a 22 Kohms resistor R.sub.t providing a 5-10 milliamperes trickle current in the case of the preferred embodiment. www.freepatentsonline.com /4853607.html   (5089 words)

Alpha4 FAQ The charge acceptance of battery is higher at the slower charge rate of "I" charger and leaving it for several hours on trickle puts small additional charge into the battery. Charge acceptance of batteries is higher at low current charge rates so use "I" charger and leave for couple hours on trickle when time allows. At C/50 continuous trickle charge the battery longevity would be considerably higher than at C/10 continuous charge but slightly lower than if battery was not continuously trickle charged. home.att.net /~LitcoSys/a4faq.htm   (4990 words)

Trickle Charger Information   (Site not responding. Last check: 2007-10-15) There are basically two types of trickle chargers, the first uses electronics to insure that the trickle rate is "forced" into the battery and the second ends up suppling the trickle rate by design. The idea of a trickle charger is that it can be left charging the battery continuously without fear of damage to the battery. As I described before, a trickle charger can be of two types, one that always supplies the trickle rate of current, or the one that starts higher but ends up at the trickle rate. www.qsl.net /ke3fl/htm/TRICKLE.HTM   (2224 words)

Agent Orange   (Site not responding. Last check: 2007-10-15) The American Legion, Vietnam Veterans of America and other veteran's groups are charging a massive government cover-up on the issue of herbicide exposure because of the hundreds of millions of dollars in health care and disability claims that would have to be paid. That report, released August 9, 1990, charges that officials in the Reagan administration purposely "controlled and obstructed" a federal Agent Orange study in 1987 because it did not want to admit government liability in cases involving the toxic herbicides. In charge of the CDC study was Dr. Vernon Houk, director of the agency's Center for Environmental Health and Injury Control. www.usvetdsp.com /agentorange.htm   (10373 words)

Trickle charging, removal, testing a BMW motorcycle battery, jump starting Since the first resting voltage reading of 12.71 is under the recommended charge voltage of about 14, the test was made after the surface charge had dissipated, that is good.

Part Selection Guide Its job is to monitor the charging process and to control the fast-charging regulator to ensure that the battery pack is charged safely. The charge controller uses this divided-down voltage to sense the charge state of the batteries. Normally the charge controller can terminate fast-charging correctly by sensing the pack's voltage, but there needs to be a backup method in case something goes wrong with the cells. tangentsoft.net /audio/ppa/bb/pguide.html   (2549 words)

Trickle Charging Multiple Batteries   (Site not responding. Last check: 2007-10-15) A: If the batteries are the same voltage and roughly the same capacity, vintage and condition, you can connect them in parallel (positives joined together and negatives joined together) and charge them as if they were one battery bank. There’s no need to keep the charger on all the time, as all you are trying to do is replace the losses from periodic self-discharge. Here’s the routine: once a month connect the batteries in parallel, top them up to full capacity with a regulated battery charger, then disconnect the positive wires so they are electrically isolated during the time between charges. www.diy-boat.com /Pages/search/search/tb9_021.html   (142 words)

Trickle-charging solar panels I am setting up a solar panel to trickle charge a battery (280-320 CCA non-deep cycle, non-heavy duty, from memory, smallish in other words) driving a bilge pump only. John, such a trickle charger would only be satisfactory for maintaining the battery in good condition as long as there is not a serious discharge, as from extended use of the bilge pump. As long as the battery has no drain on it, the trickle charger will maintain it in good condition for a long time without need for recharging (given sufficient sunlight to keep the thing kicking along). www.westernangler.com.au /forum/fb.asp?m=22643   (377 words)

Re: jump-starting or trickle charging?   (Site not responding. Last check: 2007-10-15) From my personal experience, though, if you've pulled the voltage down to 4.8 volts, "driving it around" may not get you back to full charge unless you drive around the US.
