How do I generate electricity using weaked dry cell batteries, table salt, water and the solar system.?

Question by Solomon Titiloye Oyebanji: How do I generate electricity using weaked dry cell batteries, table salt, water and the solar system.?
This system is being used in a village in Ogun state, Nigeria., but the inventor is unwilling to reveal the basics. The rule is that water should not dry from the installation point.

Having trouble understanding your question. “weaked”? Is it wrecked (broken) cells or weak cells?

If you have the entire solar system, you can do anything. I think you mean a solar cell?

“water should not dry” doesn’t make any sense.

If you have weak batteries and a solar cell, you can charge the battery from the solar cell.

Solar energy- does anyone know of a DIY way to make a solar collector and transfer that energy to batteries?

Question by Ex Californian: Solar energy- does anyone know of a DIY way to make a solar collector and transfer that energy to batteries?
I would like to learn about solar energy and how I can make some panels for my home, of course with in a reasonable budget. My goal is to be able to run a refrigerator and fan off of battery. Any ideas out there?

A larger 145 watt DM solar panel used to boost tractor batteries

This is an alternate use for a larger solar panel at a remote farm location. The entire place was snowed in, with the best tractor for clearing roads stalled out by a field and with a dead battery. One of the guys hiked a panel down there and hooked up a panel, after about two days, he was then able to start the tractor and clear the road enough for 4×4 traffic. Without the panel, there was little or no way to charge the battery since we could not get another vehicle to the tractor in order to jump start it, and nobody was eager to try and haul a fresh tractor battery through the snow.

Olympus Batteries – Solar Chargers?!?

Question by A Bloke Named Smokie: Olympus Batteries – Solar Chargers?!?
Ok so the scenario is this,
In July i will be travelling to borneo for a month. I have recently purchased an Olympus Mju 6000 Tough for the sole purpose and intention of the prevention of dropping the camera in water/ mud / in general!
Anyway straying away from the point the camera doesnt take standard AA batteries. What i was wondering was whether i can charge the battery (Li12b) using a solar charger and if so any makes that are better than others.
Many thanks for your help

You really need to invest in a couple of spare batteries for the camera.

You can use one of the solar chargers, but it will take much longer to charge the battery than being plugged into AC power does. How much longer depends on the charger, which will depend on your budget and how big an article you are willing to carry.

Here is a fairly inexpensive unit, that would probably require further adapters to work, but is portable and lightweight… http://www.batterystuff.com/solar-chargers/PF6.5w.html
This website has many options… and if you search on your favorite engine, using “solar battery charger” or similar, you will find many more.

Solar energy again: Will this kill my batteries?

Question by Gabby: Solar energy again: Will this kill my batteries?
ok,i have two panels, 165w each, 24.2 v i have them connected in parallel to two 6v connected in series and a 12v thats connected in parallel vith the 6 v ones…if i connect the panels in series will this kill the batteries or will it it give it more charge? i’m experimenting with solar energy :) and loving it1 thanks for your time and help.

It sounds like you are charging 12 Volts worth of batteries with 24 Volts worth of solar panels. Without some sort of regulation your batteries would “boil” away over a period of days. The maximum voltage on a 12 Volt battery should be about 14.5 Volts. Otherwise yes damage will occur.

i know costco doesnt make their own batteries, they just rebrand them from Johnson Controls Inc, but i still cant find much info on them. im pretty sure they are supposed to be maintenance free but they dont say anywhere and there are just 2 square vents on each battery that i dont want to pry on to see if they open just in case i might break them. im using 2 of them in series for a 24volt solar panel system with a xantrex c40 charge controller where you can choose the bulk and float voltages, in the manual of the xantrex c40 for “maintenance-free rv/marine” batteries it suggests 28.8v bulk and 26.8v float (divide by 2 for each individual 12v battery). and for “deep cycle, liquid electrolyte lead antimony battery” batteries it suggests 29.2v bulk and 26.4v float (divide by 2 for each individual 12v battery). but my batteries say they are deep cycle AND marine batteries, should i average the 2 together or what? are these even good bulk and float voltages? i know the batteries go up to around 12.84v or so each when fully charged, can someone help me out? thanks

Marine means that they are more rugged and can take the abuse of a marine environment. I would got with the voltages for the deep cycle batteries.

1.2V AA batteries on Flashlight that specifies 1.5v AA batteries?

Question by Mentalbox: 1.2V AA batteries on Flashlight that specifies 1.5v AA batteries?
I’ve ordered a Fenix LD20 flashlight. But as specified on amazon.com, “Uses two 1.5V AA (Alkaline, Ni-MH, Lithium ) batteries”.
I need/want rechargeable AA batteries, preferably that can be recharged with a USB adapter.
So what I have looked up is, amazon-title: “Sanyo Eneloop 2-AA NiMH Pre-Charged Rechargeable Batteries with USB Charger”. From what I understand, these are 1.2V. Will my flashlight work and omit a sufficient amount of light (i.e. not less than 80% of normal) anyway with these batteries?

Note: I am Norwegian – non-US, so whatever optional item you consider better must be available to me via eBay or other services with low shipping (Amazon has changed to extremely expensive, 100$ ish shipping to Norway). And again: remember I need the USB charging option (I will be hiking for a long time, and I have an external battery with USB port + solar panel)

Most primary (non-rechargeable) cells are 1.5 doesn’t matter if they’re AAA, AA, C, D.
“Most” rechargeables are 1.2. There is a slight difference in diameter usually (larger) – this normally has no effect, but I have one flashlight that rechargeables get stuck in – almost impossible to get out – don’t force rechargeables into anything.

Most anything a non-rechargeable works for a rechargeable will too. They have a shorter run time than a non-rechargeable. I don’t see any difference in the brightness although common sense would tell you there should be some.

I have 100s of rechargeables that I use for everything from power tools to flashlights, guitar tuner to digital voice recorders, digital cameras to portable jobsite radios, and my mp3 player.

I do suggest you get an extra set of batteries – and yes any rechargeable battery will charge on any charger designed to recharge that model (AAA, AA, C, D) and chemical makeup battery – you must use a lithium battery charger for lithium batteries. My lithium chargers will charge NiMh and NiCad (don’t use NiCad if you can avoid it – I have to for some power tools) – I’m not sure if all will or not – they’re a bit hard to come by as are the batteries. A NiNhd charger will also charge NiCads but it will not charge Lithiums.

Lithiums are much better (longer runtime, longer shelf life) than Nickel Metal Hydride and are coming into the market place. I have a rechargeable lithium battery pack for a camera that is really just two AAs – but they cannot be taken apart. I also have some rechargeable CR123 lithium. So far they’re hard to find and expensive (but still worth it).

I don’t understand the “whatever optional item you consider better” thing – sorry. You stated that you “have an external battery with USB port and solar panel” – don’t know what optional item you would need besides that.

You can order rechargeables/chargers off of eBay. Most any brand. There are also many cheap(er) Chinese made ones – I have found them to be good batteries but it takes a while to get them here (U.S.). Shipping was very reasonable and there were no customs charges (sent as “gift”).
