As expected with Zinc Carbon the capacity is low and the current handling is very bad. It also looks like there is significant capacity differences between the batteries (the 0.002mA trace is shorter than the 0.005mA trace).

Conclusion

For a Zinc-Carbon battery this is fairly decent, but that do not mean it is a good battery, it is only to be used on low power loads.
