First , for the dg batteries . I thought these were a great deal since they cost $ 4 for a pack of twenty .

首先，对于dg电池来说，我觉得它们物有所值，因为一板20节电池只要4美元。

If I used the cheaper dg , I would just have to replace the batteries more often .

如果我用了便宜的dg电池，我只不过是要多换几次电池而已。

Either way , the duracell and the energizer batteries seem to have similar curves , but the dg is significantly lower .

不过不管怎样，duracell和energizer牌的电池有着相同的曲线，但dg牌要低很多。

Dg booth is crowded with readers who show immense interest in our products .

展台前，读者对贝塔斯曼的产品兴趣浓厚。
