pecially when heated, is extremely ruinous to metals or rubber compo- sition. Imagine. if you can, hot sul- phuric acid in your battery, and you will appreciate why in the old style battery it is necessary to burn your lights in the day time (when making a long run) if you pay proper atten- ton to your battery.
 Possibly the greatest damage caused by an overloaded battery (coramoniy called overcharging) is that the plates have a tendency to buckle or warp, and the larger the plates, the easier they buckle and warp. In the Gill battery, regardless of it's size, the plates are placed crosswise of the battery jar. instead of lengthwise, resulting in our being able to place a greater number of thicker plates, spaced farther apart, than in any other storage battery. There is a hard rubber rib at the edge of each plate, covering only the lead frame of the plate. giving the entire active portion of the plates free and unhhmpered chance to act.
 By reason of this patented feature we use a weaker acid solution, which is much easier oh the plates and adds life to the battery, at the same time giving us enough acid to get full ca- paeity from the batteries.
 Tested for Six Years
 'The Gill battery has been tested for over six years and during that time we experimented by using paste instead of liquid in the batteries, with the result that because of separators (regardless of what they were made of or their porosity) the internal re- sistance was even greater with paste or jelly than with an ordinary acid solution We adopted the use of a weak liquid eleetrelyte, because it's constituency permitted an absolutely free circulation, thus cutting down internal resistance, and since inter
 nal resistance is the cause of at least 95 per cent of all battery troubles and knowing that the motorist wants
 service, we found the liquid by far the most practical.
 "The Gill battery does not need to be filled with distilled water nearly so often as the old style battery built | with separaters, due to our double water capacity. Gill batteries do not require half the attention that must be given other batteries It might be possible to drive your car for months without ever looking at your Gill battery, only by doing so YOU would not be able to know the
 
 1 cause of this failure to give it proper l attention before it was entirely ex- | hausted. We could tell you of sev- | eral Gill batteries that have been 1 constantly in use for as long as three | months without having any attention whatever. An ver-enthusiastic mo | torist drove his car, equipped with a ! sealed Gill battery from the Pacific 1 coast to the Atlantic coast. and up- on his arrival at the eastern coast he 1 found his battery with as much pep
 as when he started, and with enough 1 water left in the battery for a re- turn trip.
 Because of the absence of separa
 tors and the internal construction of | the battery, it can be taken through 1 a complete cycle in about one-third | of the time required for other bat l teries. Let us explain the meaning l of a cycle. For example, the Gill bat | tery can be taken when at full i charge and completely discharged l aDd recbarged in about one third oi
