Yeah, Concorde goes to great lengths to nyah nyah nyah about the strength and integrity of it's jars.
Every type of battery has it's strengths and weaknesses. Positive and negative points. As I see it, it's the job of a consumer to make themselves aware of the two lists and then make an intelligent choice.
In my case the compelling reason to go Lifeline, was two-fold. The first is the battery is fitted beneath my bed - AGM. The second consideration is that the sucker doesn't up and die on me. In Mexico you'll find the Concorde dealer right behind the Rolls Royce agency.
But a good quality truly cyclable battery is a lot less fraught with quirky idiosyncrasies than the Friday the 13th scenarios as have been described on this site. Inferior battery syndrome will fill a library. Around a half dozen vendors I consulted to, dropped all golf car battery lines except Trojan. Crunching numbers proved proof positive that when they handled the competition they lost net income - a lot of net income. One of the prime factors in making money in the storage battery game is to ruthlessly minimize warranty claims. When a distributor vends a thousand brand X batteries and has a one-year warranty factor of <1% versus a 20% cheaper brand Z battery with a 4% warranty claim factor, the distributor loses net money. A lot of money.
Landy, an insulated thermal blanket like a reflective windshield shade, with a quarter inch of free space inside to aid convection is about the best "inexpensive" battery protection device I have yet found. Too bad my toad has z-e-r-o space to incorporate this. This works well if an issue exists with direct radiated heat like given off an exhaust system. Swatches of Velcro on the barrier and on the jar would work for this.
The relationship between grossly elevated electrolyte temperature and reduced battery lifespan is scary. If you can move air upward beneath the battery and duct it beneath the thermal shield, do it, is my advice. Watch vehicular system charging voltage! A 5% antimony battery at 14.0 volts at 50C is too hot. Period! Plate erosion and shedding at those values is almost cosmic in scope. You don't want to know the numbers.
