61 -- MARKET SURVEY FOR MAINTENANCE FREE BATTERY POC Walter Grudus, Engineer, (908) 532-8489. This is a Market Survey to locate sources for Deep Cycle Sealed Maintenance Free Batteries (MFB) which meet or exceed the requirements of a Battery Bank consisting of two 12 V batteries in series connection for providing 24 V back-up power in the Mobile Subscriber Equipment Shelters. The following describes the characteristics and operating conditions which the MFB Battery Bank in the MSE shelters must operate at without being degraded or damaged. The Operational Requirements include: Continuous float voltage of 26.5 Volts; provide back-up power for a minimum of 10 minutes with an average current of 97 A to a battery bank voltage cutoff of 20.5 Volts; recharge at a constant potential of 28+/-.5 V, 100A peak charge current (Equalize Charge Mode) for a 5 hour period followed by continuous float at 26.5 V. It should be noted the float voltage and the equalize charge mode voltage settings could be changed up to +/-5%, but is not desirable. The Environmental Requirements include: Operating Temp -40 deg F to + 120 deg F; Storage Temp -70 deg F to + 160 deg F. Virbration and Shock in a Military, Ground, Mobile environment (Reference Non-Operational Random Vibration MIL-STD-810E Method 514.4, Procedure I, Non-Operational Shock MIL-STD-810E Method 516.4, Procedure I. Commercial data will be considered). Physical Requirements: It is desirable each battery not exceed 10.25 inches long, 5.31 inches wide and case 8.19 (to top of terminals 9.07) inches high. An alternative is two batteries fitting into an enclosure having the internal dimensions of 14.25 inches by 11.75 inches and 11 inches high and a cover having a depth of 1.75 inches. Max. weight (each battery) 50 lb. Notice: The Battery Bank is used inside a manned shelter and safe conditions must be maintained. Therefore, information must be provided regarding venting requirements of the MFBs based not only on normal operating conditions but must consider all failure modes. Response: Interested parties are invited to submit a written response to this notice within 30 days. Responses should include, as a minimum, the following: 1) Detailed technical description of capabilities satisfying this requirement, 2) Available test data verifying operational characteristics, 3) Provide general cost information on your available products to include most economical order quantities (lots of 100, 1000 and greater) 4) Availability of your product. 5) Point of contact for any additional inquiries if necessary. It would be appreciated if all responses and questions concerning this announcement be addressed to: OPM JTACS, ATTN: SFAE-C3S-JTC-ITI (Mr. Walter Grudus), Ft. Monmouth, N.J., 07703-5506, Telephone (908) 532-8489 or 3525. This announcement does not constitute a request for proposal, but is solely for the purpose of planning by surveying the market for qualified sources interested in the above requirement. No formal solicitaiton is available at this time. (0296)
