This is not a "hot" deal, but an everyday Walmart deal for some, depending on one's needs. About 2-1/2 years ago I purchased one of Walmart's "value" car batteries at $50, which is about 1/2 or less than you would pay for a regular battery, though the value batteries are only warranted for 1 year. But if one has a car that is a spare, or one that is near EOL, then it's a pretty good deal, and I suspect that these cheap batteries will probably last 2 to 3 years without problems.
Isamorph, sometimes I wonder if you and I are somehow related ?!?
As it happens I also got one of those for my (now) 24 year old car most of 10 years ago...
Given the rather deep cold we get here as well as my car sitting very much of the time, I also found a great deal on this thing:
"BatteryMINDer Model 12117: 12 Volt 1.33 Amp (12V 1.33A) Charger/Maintainer/Desulfator "
It is just a tiny little 'wall-wart' plug-in box with a couple of LEDs and its cable and draws next to no power.
Put it on the car when I know it'll sit for a while - take it off when I'm ready to use the car - and it has literally ALWAYS started up EVERY time (even when its been -30F), thereby giving me ~10 years from that '1 year' battery.
Well worth what it cost me - 'specially since I've been able to keep that same battery all this time - which to me means its paid for itself a bunch of times over.
($30 today at 'zon, goes on special there & at Northern Tool for ~$25 every so often.)
Perhaps this is why dire illness hasn't done me in yet ?!?
The function that prolongs battery life for a lead/acid battery is the desulphator part - which imposes a frequency upon a slight charging current that in effect keeps the battery 'young'.
Ordinary trickle chargers do not have that - and most desulphators are either too crummy to actually work well, or very, very spendy.
(I even considered a DIY desulphator before finding the one I got for less than I could make one, and with ratings which were encouraging enough for me to get it - been glad I did every since !!)
If it were me - there - with all that good sunlight around, I'd pair this desulphator up with a 110V solar power source, ass-u-ming such a thing could be had without $pending a fortune, that is !!
Thanks for the desulphator info E_Z. I wouldn't mind forking out the money for even a pricey desulphator if I could also attach it to my fingertips right before I go to bed at night in an effort to extend my EOL date, for going to and soaking in the nearest sulfur springs is a hassle.
