Trijicon's SRO and RMR HD are among the best open emitter MRDS in the market. SRO has a battery life of about 3 years with brightness set between 4 and 8, while RMR HD's exceeds 3 years with the brightness set at 5. Our SRO lasted 4 years before the battery had to be replaced, which was when we discovered the joy of removing and reinstalling an SRO battery cover.
Both the SRO and RMR HD have the battery cap partially masked by the hood of the sight, a typical screwdriver with either a flat or Philips bit has to go in at an angle that results in partial engagement between the bit and the slots on the battery cover. In addition to chewing up the slots in short order, when the battery cap is being reinstalled, it's annoyingly easy to cross thread it because the aforementioned angle of the screwdriver puts the battery cap at an angle as well while the screwdriver is turning, when it should be parallel to the sight's body.
For individual users, a simple task that's somewhat tedious only has to be performed once every 2 or 3 years. SBT is designed to make this easy and simple, it's a handy tool especially for unit and agency armorers (for whom SBT is designed) that replace batteries for their SROs and RMR HDs annually.
SBT is a dedicated battery cover tool for Trijicon's SRO and RMR HD, it is also compatible with Vortex's Defender XT and ST as well as EOTech's EFLX. SBT is designed for use with any screw driver with a 1/4" socket, its reduced diameter in the mid section allows SBT, and the screwdriver it's attached to be perpendicular to the battery cover.
Designed for use with a screwdriver that can accept a 1/4 bit, SBT can also be used with the included handle. Follow the MRDS user's manual on battery and cap installation. We like Trijicon SRO's: "rotate/turn the cap clockwise till resistance is felt. take care not to cross thread the cap and pocket threads) on page 18.

NOTE:
* Do not over tighten. The "<5 in lb" text engraved on the SBT body, it's a "do not exceed" value. Follow the sight manufacturer's instructions on battery cap removal and installation.
* We did a small run of purple handles for our purple loving friends (aka Purple Knights), and to our surprise and delight, the purple handles have become a popular and often requested item from agency armorers because the unique color makes SBT easy to find in the range bag or on the bench, also harder to get borrowed and not returned (because the handle is such an ugly duckling, presumably), so we will make both hi vis orange, hot pink and the original purple on a regular basis for them.
