Batteries and lifespans

[IrishDoc]

How long should you expect batteries ( IE; Trojan T-105's )to last and if they run dry can you add acid and recharge them ? also... anyone ever use those 12 volts like they use in busses ? HUGE batteries the sell them at batteries plus for like 150 bucks... 12 volt... 4x5 minutes run time @25 amps... etc etc i would appreciate some input

Trojan T105. They can be drained completely (to 0%) and recharged an amazing 750 times.

The battery used is the Trojan T 105 which is made in the USA and is of the deep cycle lead/acid type. Ordinary vehicle batteries are quickly damaged if they are fully discharged very often but the deep cycle type is designed to withstand regular discharge. They have a life span of about 700 to 750 complete charge and discharge cycles.

Trojan's T105 is the smallest deep cycle battery we sell. With its low initial cost and 3 - 5 year life it serves well for all manner of golf carts and some small RV and Marine applications.
