batterys

I was just wondering is the battery that is inside the blackberry bold 9700, the same battery that they use in the blackberry torch 9800? are they identical, not so much in battery life but could i swap these batteries over and would they fit in each others handsets. Thanks all in advance!!

It starts sometimes but it struggles to start. I already check the gas,filter,oil,and both baterrys. Wat could be the problem?

i have three optima yellow top battery's that need to be wired it will be one in front of the truck and 2 on the trunk
