Save rechargeable batteries from freezing
355814
Hook up a heat pad to keep things from freezing.  Extend the life of batteries for battery powered tools by using a foot warmer pad, and this to turn on and keep expensive batteries from freezing.  It can get that cold in a garage and it best not to freeze expensive batteries.  Keep them out of the charger and on a foot warming type pad connected to this to control the temp.

I understand people have been having issues with their batteries not charging after awhile but there is a simple fix that should help most of you.

When it comes to rechargeable batteries of any type they are not meant to be left on the charger 24/7. Constant charging when the battery is at maximum charge will wear it down and make it so they can't hold a charge.

My advise is to place the controllers on the charger only when the controller is getting to the point of dying. Then place it on the charger and let it charge all the way before removing it. As soon as the light shows that it is charged take it off base.

I understand that at times you need to use more than one controller or one might be dying before the other is charged but I promise you that if you can follow these steps your battery life will last much longer.

P.S. I love my charger =)

Really helps save on batteries. However the charge doesn't last as long as batteries. I just simply put the wii motes on the charger at night.

I bought two units for my wife who has severe Reynaud's syndrome in the fingers of both hands, which turn white and become numb in cold weather or when she reaches into the freezer to get something without first putting gloves on. The hand warmers provide a quick rescue when she does develop Reynaud's, and will, she hopes, prevent her from sustaining the damage to her hands that she suffered last year.  They work reasonably well outdoors down to temperatures around freezing.
 I have cold hands most of the time and like to keep one on in a sweater pocket during evenings. I charge them up at night with two iPhone chargers for use the next day. I expect as the weather warms up, we'll be using them less often. It would be nice, however, if the unit would recharge more quickly (it takes 4 to 5 hours to recharge.)

These batteries are for a "discontinued" Panasonic ice cream maker that I love. Lithium batteries are required because the machine works inside the freezer at 0 degrees. They retail for 8-10 dollars so price is the primary issue and so are much less expensive. So far they seem to work well enough.

worth it for the cost. Dont forget to keep it charged. If left alone even for a few months without a charge, it will not be any good. I left mine uncharged for 2 months and the battery depleted so much the charger and several others would charge it. Flashed as a bad battery. It is a much cheaper alternative to name brand batteries. Did hold charge in the cold weather without difficulty- around 20 degrees or less on Lake Superior in Grand Marais.

This is a nice buy for battery killers like digital cameras and the batterys are built very sturdy unlike the cheap stuff. Only one problem if you are in a rush to use your product buy a set of regular batteries too. these don't come charged. It has been five years; i am now on my second set of batteries and the charger has survuved five years. very good for a charger.

UPDATE: (Oct. 26, 2013) About a week ago, I switched the "charging function" back to "CHR ON" to see what would happen (please read below to read how to do the switch). To my surprise, there has been no more freezings so far. So maybe there was an internal "reset" of some sorts. If there are any more freezings experienced, I will report them here, otherwise it's all good.

==========================

I was really digging the PL-390 radio until I also encountered freezing problems. I played with the different settings trying to see if anything could be causing the freezing. Finally success came with turning off the "charging function" of the radio (with the radio power turned off, press and hold the "M" button until can see "CHR OFF" on the lcd screen display). Overall this has pretty much eliminated the freezing of this radio. I did experience freezing once so far when I powered on the radio, but once I pressed the power button to turn off the radio, then pressed the power button again it successfully turned on the radio without having to remove the batteries. At this time I am still experimenting with this solution, but want to pass this information on to everyone.

UPDATE: (Oct. 11, 2013) Usually when my radio is left overnight, it would freeze in the morning, and would need to have it's batteries removed and reinserted again before it will work again. This is the first morning it did not freeze and it works perfectly. As mentioned earlier about my experience with my radio freezing the one time after changing the "charge function" to off, it may have been due to an internal switching from "on" to "off" that initially caused a glitch. Once it made the switch, I did not experience any more freezing with my radio. Since I use rechargeable batteries, the downside is now the "battery indicator" meter will not accurately tell me the state of the batteries. So I just ignore the battery meter and my radio is working just fine.

UPDATE: (Oct. 12, 2013) So far so good, have experienced no more freezing. The PL-390 is the main radio I listen to in FM. It receives the stations with no problems, and I also use an external wire antenna (I use a wire antenna from another radio, but this one comes with one). The sounds from the two speakers are nice and easy to listen to, but there is no tone control switch on the radio. It is not a boom box, I keep the volumes between 8-12 (the volume dial is rotated in increments and a volume number is displayed on the lcd screen) which is equivalent to modest to medium levels (don't want the risk of blowing out these nice small speakers). The two speakers "stereo effects" for what it is works in a small way, but it is pleasing. The sounds from the speakers is fine for the bedroom or smaller spaces.  To tune into stations, I just use the keypad, I do not use the memory settings. The battery compartment can accomodate larger sized AA batteries (the other radios I have that have tight fitting battery compartments, I use the Sanyo AA batteries, they are the right size and works great).

I use them for my outside security camera and when it rains or snows the batteries lose their power! Is there a reason why your product does not keep it's power longer than a month providing it does not rain ir snow?

I have been using rechargeable AA batteries for my Nikon camera for years but they just wouldn't last very long.  I have only used one battery so far and it's been six months.

I committed to phasing out regular batteries while building up a collection of good quality rechargeable batteries (eneloops). Batteries pop in and out of these caddys easily. They're solid feeling and appear well made. These provide a solid solution for organizing & storing multiple batteries (instead of a bunch of different batteries rolling around loose in my battery storage box).

If you're going to invest in pricey rechargeable batteries the least you can do is a drop a few bucks to store & protect them properly. These caddys have fit the bill perfectly for me thus far.

I have these maintainers on my equipment over winter that i am not using regularly. Cheaper them buying batteries year after year .

works very well. A nice option to keeping spare batteries charged

Very convenient to use, the only problem is the rechargeable battery is not replaceable, This design makes it a garbage when battery weakens overtime.

I keep one of these in my car for emergencies, and one in my home for power outages. So far, they have worked and I am happy to have them as backup. This gives you a little exercise to warm yourself while doing something constructive in a blackout. I also bought one of the lantern-type units. Even if you never anticipate an emergency, it is worth having them available for peace of mind. I have used them frequently out of the car. Saves on the auto battery and works just like a battery operated unit. Plus I don't have to keep changing and throwing batteries in the cold weather. So far, a nice dependable unit.

easy to intall and to use. it preserves battery life when not in use, so that the batteries do not prematurely die.

i have both of these remotes in freezers... with lithium batteries. I love knowing the temperatures in my freezers without opening the door... especially when the power goes out.
