Ways to eradicate the battery memory impact

What's the battery memory result?

If the battery is nickel cadmium battery, long-term will not be complete charge and discharge,it easy to leave a mark within the battery, the battery capability, this phenomenon is called battery memory effect.That mean, it appears that battery memory consumer daily charge and discharge charge as well as mode, time is tough to modify this kind of mode, can no longer do significantly charging or discharging.Lithium-ion batteries, no such result.

The reason behind the battery memory result

Resulting from adverse really sintering form in the traditional system, cadmium coarser grains, if nickel cadmium battery recharge in advance of they may be totally discharge, cadmium grain effortlessly gathered into pieces and produce a 2s 7.4v lipo battery discharge kind secondary discharge platform.

Battery will retailer the discharge platform and it since the finish from the discharge within the subsequent cycle, despite the fact that the capability of the battery itself could be make the battery discharge to your decrease platform.During the procedure of following the discharge of battery will only do not forget that lower capability.Exactly the same in each use, any incomplete discharge will deepen this effect, make the capability with the battery is reduced.

The best way to do away with the battery memory result?

To remove the effect, there are two techniques, 1 will be to use tiny latest depth of discharge (including with 0.one C to 0 v) 1 is to use big latest charge and discharge (e.g., one C) several times.

In practice, the method of elimination of memory results have strict specs and an operating method. Improper operation will be counterproductive.

For nickel cadmium battery, the upkeep of usual is deep discharge on the standard basis: the common use to get a month (or thirty instances circulation) on the deep discharge (discharge to 1.0 V/each section, named the work out), popular use is usually to use photovoltaic cells or make use of the signifies which include shutdown can lower the formation of the memory effect, but this is not training, since the instrument (including cell phone) is not employed 1.0 V/only to flip it off everyday, has to be special gear or line to finish the do the job, but luckily a lot of nickel cadmium battery charger with this particular perform.

For no nickel cadmium 7.4v lipo battery to training for any extended time, as the cumulative memory impact, cannot reply in training capacity, you then will ought to deeper discharge (termed a recondition), this is often an incredibly small present to get a long time for every area to 0.4 V battery discharge of the procedure, want specialist equipment.

For nickel metal hydride batteries, exercise within the frequency of about as soon as each three months can properly alleviate the memory result. Since the cycle daily life of nimh battery is lower than that of nickel cadmium battery, with little recondition this strategy.

Suggestion one: each and every time there is no really need to charge the 14.8v lipo battery just before discharge, and it really is hazardous, for the reason that useless shorten the lifestyle with the battery.

Suggestion two: use a resistor connect would be the cathode with the battery discharge is just not desirable, cannot management recent, easy to 0 v, even result in series of battery cell polarity reversal
