Medium capacity NiMH from Energizer, there was no LSD specifications for the cell, i.e. they will have to be recharged before use.

I got the batteries with a charger.









The traces for the two cells tracks very fine and capacity at low load is about 2000mAh as specified















Conclusion

The cells has good performance, but I would get some LSD rated cell instead.
