BT-2B TS-2530
Survival Equipment Battery Tester

Introduction and General Information

This is a tester for a number of obsolete survival equipment batteries:

• AN/PRC-90 family that use the BA-1568/U (or equivalent)
• AN/PRC-63 family that use the BA-1568/U (or equivalent)
• AN/URC-64 family that use the BA-1113/U (or equivalent)
• AN/URT-21
• AN/URT-33,-33B
• AN/URT-27
• ACR / RT-10 Type K308A battery
• SDU-5/E Strobe light uses BA-1574/U, 4RM1B, ACR No. LLB1 or 1032, or equivalent

There are a number of battery connection points:

• PRC-90 (BA-1568/U) and SDU-5/E cylindrical on front panel
• PRC-63 & URT-21 on left just below meter
• URT-27 on right just below the meter
• K308A on the back

On the bottom is a set of graph cards that pulls out.  This converts the DC Milliamperes reading into an approximate hours remaining.
If the hours remaining are less than 60% (reading of < 0.6 mA) of normal battery capacity the battery should be replaced.
A new battery should read greater than 0.8 mA.

Since all the batteries that this tester was made to test were Mercury based, it no longer has much practical use.
