The Skinny on batteries sold in Mexico

Hi,

Freeze point of a fully charged non arctic battery is -67 C (-77 F). At those temperatures I'd have other worries.

Thermodynamics of an acid electrolyte.

VRB (AGM) generally use 1.300 SG saturated glass mats.

FYI, in the arctic and antarctic, the opposite is true. Lead-acid batteries are filled with electrolyte with a specific gravity of 1.300 or sometimes even 1.360!

One of the reasons is to prevent the electrolyte from freezing.

Hi Moisheh,

One reason they last a shorter time is that heat kills. The speed of the chemical reaction is nearly doubled for each ten degrees C. So a battery in Canada where it is perhaps a maximum of 40 C won't last as long as one in Arizona where they get 50 C. That means storage life is a little better than 50% longer in Canada.

It is also why I keep harping about temperature sensors for chargers.

Turns out he is from Johnson Controls. They not only make Costco's batteries they have 70% of the battery market He really knew his product and was very helpful. I asked him who makes Costco's batteries in Mexico. It was the same Johnson Controls. I asked him why the Mexican batteries do not seem to last very long. He stated that batteries that are sold in Mexico use a different electrolyte due to the heat. This electrolyte can withstand the heat but it shortens the battery life. He also said that Mexican batteries sold in the US and Canada do not use that electrolyte. Maybe Mexico wanderer can shed some light on this subject.

Concentrated H2SO4 is roughly four times as dense as water. It is diluted to render a 1.280 specific gravity OEM.

Johnson Controls, is sub contracting much of their production to Luis T Hernandez (LTH). Models for the USA are not sold in Mexico. Few BCI group sizes have more than a single grade. LTH batteries typically weigh-in at 95% that of premium USA Johnson Controls Wal-Mart, Interstate, or Sears batteries.

An example is the (ninety dollars) group 24, 2.1 pounds lighter

The hundred nine dollar group 34 -2.3 Lighter

The hundred thirty three dollar group 65 -3.7 lbs lighter.

Warranty issues must be conducted with the seller.

A certain someone seems to have had an active imagination. LTH Monterrey Nuevo Leon only fills batteries with BCI grade 1.280 electrolyte. When acid is adjusted for temperatures averaging 30C or greater, TROPIC BLEND specific gravity is warranted and subject to being adjusted to 1.270 SG But it is done at the proveedore. The distributor.

There is no way LTH can pre-determine which pallet of batteries is going where. Environment in Cd. Obregon or Merida is light years different in temperature than batteries used in Zacatecas or Toluca. Representatives of LTH visit major Proveedores but I've never heard of one visiting a retail outlet. Why would they do so?

Deep cycle batteries are called CICLADO PROFUNDO. LTH also markets 3 cell GC220 BCI group batteries.

Hope This Serves To Help

I don't know much about anything but I believe battery acid is sulfuric acid mixed with water at about 30 or 35% concentration. It may be mixed at a different concentration but it's got to be sulfuric acid or it won't work in a lead acid battery
