This battery has all the proper specs for my application and I have ordered it before. Very satisfied. Review: Perfect for Yamaha DX7 E! replacement battery - If you are looking for a replacement battery for the Yamaha DX7 with E! system upgrade this battery DOES work. Popped it in the battery holder, turned on the DX7 (got the RAM corrupt message) - waited 10 seconds (per manual direction) and then turned off/on. Works perfectly. ## Features - Item Category: Battery - Item Trademark: Tadiran - manufacturer: Generic ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B005FNUGSS | | Antenna Location | GPS | | Battery Cell Composition | Lithium-Thionyl Chloride (Li-SOCL2) | | Battery Cell Type | Lithium-Thionyl Chloride (Li-SOCL2) | | Battery Weight | 0.55 g | | Best Sellers Rank | #209,168 in Health & Household ( See Top 100 in Health & Household ) #490 in AA Batteries | | Brand | Tadiran | | Customer Reviews | 4.4 out of 5 stars 45 Reviews | | Manufacturer | Tadiran | | Model Name | ixtra,xtra | | Model Number | 4330206716 | | Number of Batteries | 1 AA batteries required.
