replacing rolls 450 ah battery set

Hi .
My 450 ah rolls batterys are near end of life . 24 volt system .
Suggestions ? .
Ive discounted lithium . so another wet cell set Trojan or Hella endurant ,
Gell , silicon , Carbon
Rolls are nearing 8 years, but cant get rolls again in Newzealand

Some issues with forklift batteries tend to include
- higher charging voltages (16/32/64 volts) which can be an issue for some inverters and battery chargers.
- Higher distilled water usage (and smaller reservoir in cells means checking levels more often).
- And that one battery can way 1/2 to 1+ ton very easily (need crane/concrete floor/lift gate/loading dock to move).
- Need a larger solar array because charging forklift batteries tends to be less efficient/higher self discharge rates.
The individual cells in many FL batteries are replaceable--A few folks have gotten used batteries, replaced a couple bad cells, and then used for many more years.-Bill
Bill thanks for the info about fork lift battery's ... but to get more pv id need another charge controller and not keen on the weights.
And also thanks to you for your input on this site I certainly appreciate it ..
of course thanks to other contributers .
