|Description||Raychem Batcheck Battery Tester, c. 1957-1999. Rectangular sheet of clear plastic. Images and lettering are printed in black, red and green ink. Towards the top of the sheet is a multicolored band. The band starts with a green rectangle on the left side. Then to the right are three vertical red lines. Center is a wider red rectangle. Three more vertical red lines are to the right of the red rectangle and a green rectangle is to the right of that. The two green rectangles are labeled "GOOD". Red rectangle is labeled " BAD". Running horizontally through the band is the black tester. Tester has a circle on each end and narrows towards the center of the middle red rectangle. Below the right tester circle is a picture of a battery in black. Raychem's name is printed in red towards the bottom left.|

Battery test strips are used to check the remaining charge left in a battery. The conductive circles of the strip are pressed against the battery's ends. The strip will then indicate whether the battery is good or bad using special inks.
" Battery testers depend on two special types of ink: thermochromic and conductive inks. Thermochromic ink changes color depending on its temperature. Conductive ink can conduct electricity. By applying layers of these special inks along with a layer of normal ink using a fairly normal printing press, it is possible to create an extremely inexpensive printed design that changes depending on the amount of electricity it receives."
"Raychem was founded on January 1, 1957. It grew rapidly by creating proprietary new products based on Radiation processing of polymers to meet critical and difficult industry needs for electrical circuit integrity in harsh environments. Included in these initial products were irradiated wire insulation and heat shrinkable tubing. Markets included Aerospace, Military, Automotive, Telecommunications and Electrical Power Generation markets.
"In 1968, Raychem acquired Chemelex leading Raychem to extend its radiation polymer processing technology to polymers filled with conductive carbon creating a family of "Self Limiting Heaters". This technology was further extended to produce resettable switches forming the enabling technology for the "Polyswitch" Division.
"As Raychem grew into a world class Material Science Company, additional technologies explored, developed and taken to market were Heat Recoverable Metals, Piezoelectric Materials (Elographics), Silicone Gels (Geltek) and Liquid Crystals (Taliq).
"Each year, Raychem devoted between 8 and 10 percent of sales into Research and Development resulting in thousands of new products based on the technologies listed above. Research and Product Development labaratories, in addition to Menlo Park and Redwood City were established in Swindon, UK, Kessel-Lo, Belgium, Ottobrunn, Germany, Pontois, France and Japan.
"Manning these laboratories were an extremely creative and talented group of scientists and engineers who found innovative ways to use technologies to create new products."
