Which batteries to use?

[brycen66]

This year we are allowed to use one of six different batteries per R31?. Does anyone have an advice on which to use and which not to use? Any experiences with any of these batteries?

R31:
"The only legal source of electrical energy for the ROBOT during the competition, the ROBOT battery, is one of the following approved 12VDC non-spillable lead acid batteries:

Enersys (P/N: NP18-12)
MK Battery (P/N: ES17-12)
Battery Mart (P/N: SLA-12V18)
Sigma (P/N: SP12-18)
Universal Battery (P/N: UB12180)
Power Patrol (P/N: SLA1116)"

Thank you,
