Some Real World Battery Life Data, by Cactus Jim

Battery technology has come a long way in the last 10 years since Y2K. Back in the late 1990s, I stocked various types and brands of batteries for long term storage or use. Batteries ranged from store purchased alkaline, rechargeable alkalines, NiCd, generic deep cycle marine batteries, gel-cell sealed lead acid, lithium and even the ubiquitous flooded lead acid Trojan T-105 floor scrubber batteries. I wrote dates on all the batteries and rechargeable batteries had logs kept of use and maintenance. In most cases enough batteries were purchased to allow for a reasonable statistical sampling, thus providing a real level …


Three Letters Re: Lessons Learned From an Ice Storm

Dear Editor: With regards to the battery powered carbon monoxide (CO) detector, I just want to second that. When my family went through the Nov. 2007 ice storm that took out the power to half of Oklahoma, we were running off our generator for two days. The first night I put it outside, but close to the house to help shelter it from winds. Our CO detector went off in the middle of the night. We ended up having the fire department come out and check things. It was determined that the CO came in through either the dryer vent, …


Two Letters Re: Lessons Learned from the Oklahoma Ice Storm of 2010

Dear Editor: The Oklahoma Ice Storm of 2010 is now melting away and as usual there were lessons learned.   Many of these should have been “known” before but we are never as prepared as we should be.  In that vein I am going to rehash several things that went right, a few that went wrong, and others that we can improve on the next time that “life as usual” is not. First, the setting: I live in Southwestern Oklahoma and have been here for almost three years.  About January 22nd we started getting word of an impending ice/snow storm scheduled …


Lessons Learned From an Ice Storm, by G. in the Zarks

While watching the local weather over the last few days, it has become apparent that a winter storm is heading for our part of the world, bringing with it the distinct possibility of not just snow, but significant amounts of ice. As I pondered this, it brought to mind our recent experiences with ice storms over the last few years, most notably in January 2007. I thought some of our “lessons learned” were worth sharing with others. We had been blessed with several years of reasonably mild winters leading up to the 2007 storm. Unfortunately, the good times often seem …


Letter Re: I Thought that I Was Ready!

I have just returned to my house after 6 days without power. I Thought I was ready. I had plenty of beans, Band-Aids, bullion and bullets. What I didn’t have was the stuff I needed to get through the first week of a massive power outage. We still had water, even though I had an additional 50 gallons of fresh, treated water for myself, The Beautiful Wife (TBW) and the pets. We had enough short term food that we were able to provide a chili meal for some of our friends and coworkers that were doing without. We had more …


Letter Re: The Importance of Testing “Dead” Batteries Before Recycling Them

James- I wanted to share a money saving tip that applies to inexpensively preparing for TEOTWAWKI. With so many digital devices depending on batteries these days, most of us are conditioned so that, when a device like a digital camera or other smart gadget tells us the AA or AAA batteries need replacing, we simply toss out the “dead” ones and put in fresh batteries. But are the batteries really dead? Usually, not all of them are. I have a handy little Canon digital camera that we use around the house for insurance documentation, family photo opportunities at parties, pictures …


Two Letters Re: A Simple Off-the-Shelf Solar Power System and Off-Grid Power Tools

James, Your readers recently bring up good points about the advantage of battery powered tools with solar recharging. The advice to use an inverter connected to a 12v deep cycle battery and regular corded AC tools was good advice also, since the batteries may not last very long. Having just recently purchased a set of Ryobi one+ tools myself, I found a seller on ebay selling an adapter for the one+ tools. It plugs into the tool in place of the battery then you can plug an AC DC power supply into it. This will give the best of both …


Two Letters Re: A Simple Off-the-Shelf Solar Power System and Off-Grid Power Tools

James- Thanks for the interesting article on the Ryobi 12v solar setup. Just wanted to chip in some advice on Ryobi batteries: Of the name brand cordless tools, Ryobi seems to have the worst NiCd battery quality. When used carefully, they will work well for a couple of years. If pressed hard, they will die a much earlier death. I have found that some packs will have a bad cell, dramatically shortening the entire pack’s life after only a few months. I’ve experienced this with 9.6v, 14v, and 18v Ryobi setups. Even the healthier packs, when pushed hard, particularly with …


A Simple Off-the-Shelf Solar Power System and Off-Grid Power Tools, by K. in Texas

This article is written for those who have no experience with solar power and would like to set up a simple beginner system. I have been using this system for over a year and have found it to be efficient. My goal was to put together a system which is easy to use and does not require a lot of technical knowledge. EQUIPMENT LIST: 1. BatteryMinder #SCC-015 Solar Charger 12 volt with 15 watt solar panel ($150 from Northern Tool and Supply) 2. BatteryMinder #BC2410 battery clip assembly ($10 from Northern Tool and Supply) 3. Interstate Marine/RV 12 volt battery …


Letter Re: Suggestions on LED Flashlights

Mr. Rawles, Just a suggestion about something you and your readers might be interested in. I’m not affiliated with the vendor in any way, just a very satisfied customer. 4Sevens‘ 2-AA Quark light is good for 30 days continuous on low, and a couple of hours at 200 lumens. These are by far the best LED lights on the market at this time. I hang around the flashlight-nerd subculture, and have 4Sevens lights in all my survival packs. Obviously, you can recharge LSD AA lights with solar chargers, and they’ll run off of regular AA and lithium AA batteries too. …


Letter Re: An “Energy-Independent” Village in Germany

Mr. Rawles: As an engineer interested in long term sustainability I was most interested in the item from Troy H. mentioning Juhnde, Germany. I took a look at their web site and ran the numbers to look at whether such an installation is commercially viable. The capital costs listed were EU 5,400,000 or about USD $7,900,000 at present exchange rates; It’s not clear when the overall system was constructed but the hot water pipeline system was built around 2005. Apparently, and I will have to look into this further, all of the capital costs were from public funds. This translates …


Two Letter Re: Some Observations on Fortifications Versus Camouflaged Retreats

James: Just a quick observation about the wisdom of sheltering in a missile base or some other Cold War-era fortification. While Chris is correct that history demonstrates that fortifications can and will be breached by enemy forces with the resources and determination to maintain a well-conceived siege, I question whether after TEOTWAWKI the marauders most likely to be challenging such a retreat will have the resources to see a siege through to a successful conclusion. Presumably, the scarcity of resources is precisely what would make a fortress such an inviting target. Unlike the armies that successfully overran ancient fortifications, there …


Letter Re: Some Observations on Fortifications Versus Camouflaged Retreats

Last night I watched Jesse Ventura’s “Conspiracy Theory” show which centered around the government’s cover up of the coming 2012 scenario. The show featured people converting missile silos to survival bunkers. Historical precedent will quickly point out a glaring problem with this approach. Consider that relative to the technological level of their day, European castles were more heavily fortified than any bunker being built today (by virtue of the fact that your average monarch of Medieval times had far more resources available than anybody seeking to build a shelter). Still, no castle ever withstood siege indefinitely. No matter how much …


A Preparedness Plan for a Single Woman With Children

I’ve been reading SurvivalBlog for almost a year.  I am thankful for the advice that I receive each day.  I have had a “be prepared” attitude for about 30 years, although the past two years have thrown several speed bumps and roadblocks my way.  Two years ago my son and his family were in a life threatening accident.  I spent almost every penny I had saved toward retirement to help my daughter-in-law recover.  This year I fought for and won custody of three of my grandchildren from my daughter.  So now, instead of planning for TEOTWAWKI for just myself, a …


Letter Re: Well, Well–An Amazing Find

Dear Mr. Rawles: I have owned my retreat for some years and as unbelievable as it may sound, I found a water well that I didn’t know I had. When I bought the land in the 1990s, I knew that there had been an old house there at one time, but assumed that they had either used a cistern, or drew water from the stream that runs through the property. However, I found the well. It had an old Gould’s 1HP pump at the end of 120 ft. of 2″ galvanized pipe. The well had been capped for years, or …
