Question

What's the difference

between a 6V 4AH battery and a 6V 4.5AH battery? I need to replace mine in my Coleman Lantern but can't find a 4AH anywhere. Most places say the 4.5AH is its replacement now.

That's a good upgrade too.

As the battery ages it will go to 4.0AH and lower till you need to replace it again. So starting out with more is a really good idea.

Answer
voltage and physical dimensions need to be right

More available amperage is a bonus. Your lamps will draw only the current they need.

Thanks everybody....

Got it ordered (who thought it was a good idea to GLUE the bottom side of the battery to the coverplate making nearly impossible to remove the dead one?).

Now I have to hunt down a replacement battery for my three-year old Stanley rechargeable hand-held spotlight. Called their parts department directly and discovered they don't sell them and don't even have them in their manuals because it's assumed when they die, you throw out the whole thing and buy a new $70 one. No more Stanley products for me. Since it isn't working anymore because it won't hold a charge anymore, I can't 'break' it any more than it is already, so it's time to pull it apart and try to ID the battery model and type. REALLY pissed off right now....power goes out here frequently compared to other parts of this State even in good, sunny, warm weather, so having alternate light sources is necessary...having unreliable devices for that is money wasted. Thank you, China, for making crap and Stanley for accepting it for profits over good customer relations and thinking it's OK..

FWIW

If you have frequent power outages, you may want to invest in one of those LED camping type lanterns you can carry by their handle. I bought several UST brand from Amazon a couple of years ago when they were on sale for about 15 bucks (normally $30+) and they've been great. The ones I bought have some kind of glow-in-the-dark shell so they're easy to find. I keep one on a nightstand. They're said to last 30 days on low brightness but I've not tested that. They do use 3 D size batteries which aren't cheap. For a much higher price, you can find them as re-chargeable but, in a long power outage situation, that feature is useless. I'd not buy the cheap ones from Amazon that use AA batteries as they don't give much useful life. LEDs, as well, are different in that they have a trigger voltage need so don't just fade away as the batteries weaken. They just shut off. Of course with standard alkaline batteries, the lantern should be opened once in a while to make sure none have leaked. I liked the ones I bought and even gave one to my son and daughter.

Stanley spotlight

I finally managed to take it apart an discovered that the three cylindrical batteries inside are separately wired internally within the battery end to a computer card...so it's all been tossed into the trash.

I did buy a few months ago some low light (maybe 40-60 watt) bulbs that have rechargeable batteries built into the socket end. You screw them into a lamp, run the lamp for about 8 hours to fully charge the bulb and when the power goes out, they turn themselves on automatically after about 15 seconds. They also came with a portable small socket you can screw charged ones into that has an off/on button and a hook so you can literally walk around with them or hang them somewhere. Some freaking genius is making a mint because I bought ten of them for all over the house and one sits on my nitestand as a portable in case the power goes out in the middle of the night so I can easily make my way down the steps and see my dark colored dogs so I'm not tripping over them. The charge lasts for up to a year sitting alone and is constantly recharging itself in the lamps that I use frequently.

I have many light sources here that also use different battery types so I don't have to use my generator to plug in a light and waste the fuel...that gets saved for priority list items like my freezers and fridge, but I can swap out the plug for a short time and make coffee or cook on my electric hotplate. I still have to fill my tub ahead of time so I have a water source though if I've got warning or a suspicion the power will fail....have to flush toilets and water the dogs and cats.,,,otherwise I have bottled water in the fridge for drinking myself, since my water is by well and no power means no water. I still haven't figured out after so many years how to warm the crawlspace during a power outage to keep pipes from freezing but so far I've been lucky. I do keep a heat lamp under there directly on my compressor throughout the whole winter and it generates enough heat that nearly the whole area of 40X30' is above freezing all the time.

No need to warm the entire crawlspace during a power outage, do what we do up north.Put a 'heat source' ON THE PIPES

Then put some foam pipe insulation The more insulation the better. you may not even need the heat source.

Since you are on a well, you need power to use the well, put the heat trace on the same supply as the well.

PS..MY water lines are laying on top of the ground with heat trace and pipe insulation...exposed to all the elements (minus 20 and snow)....they have never frozen as long as the heat trace had power and were functioning...

I'm not sure what you mean by "heat trace",

but I think I do. Good, cheap "insurance" here in NM, too. I just bought a 13 footer for a few bucks.
Two layers of pipe insulation are good, too. The 'snap on' black foam, sized for the pipes, covered with a layer of fiberglass pipe wrap.

Except for the digging, 18" depth is recommended.

Doesn't kill the need for insulation, though.
Out here we had a winter with a -22° F surprise in the higher, exposed places a few years ago. Depth alone wasn't enough. Don't ask us how we know.

Good one, although I think she did better than

we advised her. (See below).
D cell expense isn't so bad, when comparing their much longer life to AA or AAA, as you stated.
IMO C and D cells are going up because of lower demand. AA are fine for most LED uses, bigger cells aren't for hand-carry devices, yet the market is still too large to walk away from. When it is, they will.

The funny thing about LEDs is that you don't know

when the battery is weak by the amount of light cast. At somewhere around 1.1-1.2v, the LEDs just don't light. Larger and more costly cells have several times the amperage as the triple and double A types. What I recall from my very early electronics classes is that LEDs needed about .6v before they'd conduct. Transistors had similar properties and such is why some kind of forward bias was needed in audio applications in order to produce a complete sine wave. Too much forward bias just produced extra heat. If these were power transistors that drove speakers, you could burn out the coil. Of course none of that matters with flashlights but I find it important to know when the LED types fail to light up. I have a DVM and will test the batteries occasionally. Once they get below about 1.3v I remove them and put them to other use if I have the need. It does seem like a waste, however, because plenty of current is still available in these larger cells.

I rarely tout brands here, without a technical reason,

but Stanley used to be a top brand largely because of their quality. (Over a hundred years old, with some iconic tools associated with the logo.)
Now its all made in China. Still IMO the fault lies with Marketing pressuring Engineering; IOW the usual. See Dilbert. Happy

I had the same feelings about Stanley

which is why I spent $70 for this spotlight....thought it would last longer than 3 years, get more than a handful of actual uses out of it and would be able to buy a new rechargeable battery for it. My Coleman lantern has a rechargeable battery, used it for the last 15+ years EVERY time the power went out, and love the product. It was worth trying to salvage it and was able to keep a very dependable item. Well worth the money and still haven't had to replace the bulbs yet, but bought replacements anyhow....it stands to reason that they are the same age as the battery so it's just a matter of time.

spotlight much better

I agree that the spotlight will be a much better investment.

I liked the idea of a spotlight

not only for the house and land situations (23 acres of woods here), but also for my truck because it had a cigarette lighter adapter for it. I'm looking around for a good replacement now other than another Stanley since I now know theirs aren't worth the money spent.
