I am not convinced that wave form would disable your analog meter.
- The waveform is likely showing VOLTAGE not CURRENT. You need an "amp clamp" or shunt to read current
- Meters, true analog or DMM are just not "fast enough" to read the pulses
- Pulsing a load (the battery in this case) is a common method used in modern (>40 years) electronics for controlling power. Think of filling a bucket with water from faucet. Bursts of water control how fast the bucket is filled. Very small burst means it take longer.
