Product Questions Answered by Jim, the Water Pump Expert
Hi Jim. I heard this does not come with terminal posts. Is this true? If so, what part is required?

Jim, I have the Wayne esp25 back up pump but have no idea as to which battery is the best fit for it. Should I get the AGM or this Wayne wsb1275 acid filled battery?? Your thoughts please.

It is not clear from the picture what type of connection is accommodated from the backup pump. My 3 year old Wayne ESP 25 backup sump pump control box unit has ring terminals for the two battery connection leads. Will my ring terminals connect directly to this WSB1275 battery, or do I need some type of adapter?

Can anyone, without knowledge of electric connections, or plumbing, install the battery to an existing sump pump?
