LOMO recommends SR-44 batteries. There are bit different batteries - LR44. They work well too. Difference between SR-44 and LR44 is that SR are silver batteries, and LR are alkaline ones.
All our cameras were supplied with LR44 batteries, and we never had any problems so far (during more than 5 years).
These batteries are quite cheap, so there is no any sense to sell them by 3 pieces (actual shipping charge is higher that price of the 3 batteries). So, it is more cost-effective for you to buy whole package of 10 pieces.
