Untitled

This article should be supplied with a section on inductive chargers.

Section vehicle battery chargers seems to have been written in Japanese english. Difficult to decipher.

The end of the article says that a float charger won't let the battery fall below 100%. Clearly, something is messed up. It's at the end of the section on prolonging battery life. — Preceding unsigned comment added by 74.77.148.238 (talk) 18:49, 30 August 2017 (UTC)

Inconsistency in detail

This article has a large amount of detail on some battery types e.g. (NiCd/NiMh) and very little on others (Lead Acid). The detailed subject matter needs to be split to specific pages for the chemistry involved, with this page a general guide without the detail. — Preceding unsigned comment added by 210.48.109.206 (talk) 21:38, 11 October 2012 (UTC)

High frequency battery chargers

Can someone add a section on high frequency battery chargers? I would myself but I'm not familiar with what they are. Thanks. ChelseaH (talk) 17:08, 14 September 2009 (UTC)

USB battery box

USB battery box now redirects to Universal Serial Bus, so I've removed the link from 'See Also'. Also, what was this statement (which I removed) saying?:

One can also use the USB port to provide power to a device (USB battery box ).

Is it just talking about USB devices that draw power from the bus? I don't think that's relevant to this article. (The link goes to a product category listing on thinkgeek.com, but not all of the devices even use USB.)

This is just examples of actual (USB portable battery charger ). — Preceding unsigned comment added by 188.29.164.171 (talk) 21:23, 8 September 2015 (UTC)

References

"Short circuiting" section

How is this relevant? — Omegatron 01:58, 19 June 2007 (UTC)

Is this always true? If the output is from a simple rectifier, shorting it will damage the diodes/leads/transformer. I am editing the article appropriately —Preceding unsigned comment added by 130.207.225.128 (talk) 18:15, 18 October 2009 (UTC)

Broken link

Great. Reference 15 (on solar chargers) went dead. Is it to be removed, commented out or what?
MaxDZ8 talk 21:46, 21 January 2008 (UTC)

Please do not delete a citation merely because the URL is not working. The WP:DEADREF guideline has advice on what to do when a link goes dead. Thank you. --DavidCary (talk) 16:47, 27 January 2021 (UTC)

Fast chargers

Some fast chargers, such as those made by Energizer, can fast-charge any NiMH battery even if it does not have the control circuit.

I've heard that these shorten the life (number of times you can recharge) of batteries. (Possibly related to overcharging.) Does anyone know if this is true? If it is, it should be mentioned in the article, with a source if possible. Jobarts^-Talk 20:51, 26 May 2007 (UTC)

USB as a power source to charge small devices eg mobile phone / media player

attempted inclusion within 'USB-based' section of the sentance...

"The simple electronic circuit required to mimic an active USB power source is a 10 to 15k resistor between a 5V+ve and joined data conductors."

despite reasoned discussion, intransigent from User:HumphreyW, the sentance was removed. Help, i'm becoming disillusioned with Wikipedia :( 79.76.197.119 (talk) 14:24, 4 September 2009 (UTC)

To any other editors, please take a look at my talk page to see some history of the discussion. I do not feel that any reliable source has been presented to support the inclusion of the material. HumphreyW (talk) 14:59, 4 September 2009 (UTC)

Mobile phone charger (main article)

Seeing as mobile phones have their own main article, independent of telephones, and the significance of mobile phone chargers (standard, dock, coin-operated, differing standards, manufacturers, issues (environmental and usage)), I (The Z ^UKBG (talk)) am creating an article as a main page for mobile phones, so more information can be included, as well as its own references, and detail about devices and standards, in addition to images and comparisons.

I am at an early stage right now, but the article draft is available at The Z ^UKBG (talk) and will be constantly updated. Please help contribute and feel free to add to the discussion section on the subpage in question. —Preceding undated comment added 11:57, 28 October 2009 (UTC).

I recommend only a mention and link, in this article, to the Passey biographical article which should contain whatever amount of detail is appropriate. But then, as mentioned in the article already, a mobile phone charger isn't really a charger; it's merely a wall wart, so perhaps a separate article would be proper.

charger industry

size of: cell phone charger industry? different types of chargers and their industry size? (laptops, PDA's, solar cell, etc.)

Do you know you can charge a high voltage battery and low voltage battery? You can charge a high voltage battery with a low voltage recharger (ie 12 volt recharger can recharge a 36 volt system). You make a substitute input transformer, for instance I will explain converting 12 volts to 36 volts. Just get magnetic wire (or heat copper wire to 500, idk, i think copper wire alone may even work), make 12 turns to the neg around a pencil, then attach the neg wire to the coil. Then make 36 turns or around that, attach it to the posi end, if your new 'mini transformer' is dangerous persay, add vertical loops to the horizontal coil structure. If you need to up the voltage, use the equation of 42..eg 42 as a constant, where 2.21 volts x 36 = 72 & primary's 2.21 volts x 12 = 26.52. So the Secondary will have 72 rings whilst the primary will have the given 12. You can even use low voltage batteries to recharge the battery. And in most cases, if not left on for too long, will revive the battery. The coils on each battery terminal acts as a secondary (pos many turns) and primary input transformer (neg few turns, usually as many as the given battery that is recharging). This is how the industry should make low voltage chargers to be compatible with 12, 24 and 36 volt systems to even 48 or watever. There your 12 volt battery charger or battery terminal even will work on a given higher voltage rating. Rec for high voltage systems above 12 volts. Low voltage systems can be recharged with a 12 volt battery and fan to the neg of the recharging battery, the coil would create a constant. The only glitches that may arise is that your input transformer may charge more slowly. The industry should think about this (narrow long coils=slower electrons, wide few turns=faster electrons&input transformers), they could make a multi-purpose charger in doing so. — Preceding unsigned comment added by Asfd666 (talk • contribs) 14:14, 24 October 2014 (UTC)

Unnecessary detail

"As a possible solution to traffic congestion and to improve overall efficiency by minimizing air resistance and so reduce energy consumption, the test vehicles followed the power track in a convoy formation.[25]"

The section about charging by induction is about the method of charging the car, the details about how the experiment was performed does not seem very necessary, so I have removed it. Ducksandwich (talk) 20:08, 13 March 2014 (UTC)
