A lead-acid battery, by its very construction, exposes working personnel to four potentially dangerous elements: sulfuric acid, explosive gases,
A sulfuric acid solution is used as the electrolytein lead-acid storage batteries and has a concentration of approximately 40% by weight of sulfuric acid in water. Even in this diluted state,sulfuric acid is a strong oxidizing agent and can burn the skin and eyes and "eat" holes in clothes made of many commonm aterials.
An explosive mixture of oxygen and hydrogen is produced in a lead-acid storage battery during the charging process. The two gases can combine explosively if a spark or flame ignite them. Because hydrogen is so light, it normally floats away and disperses into the air before it can collect into an explosive mixture. However,if it accumulates into gas pockets, it will explode when ignited.
Also Wetcells are notorious for having really high internal resistance. Some are really slow on recharge arnt as quick as the newer AGM's Etc.
I thought id give these a try because of the safety spec post on them. The lowered internal resistance, a quicker Reacharge, better holding time, and better short term burst power. PRICE is SICK and They are local.
