The 36 volt Taylor Dunn utility cart uses six 6 volt GC2 batteries.
The recommended amp hour rating is 240 ah. The Trojan T-125 6 volt battery is a great replacement for the Taylor Dunn cart. When we performed the battery install, we noticed that the original batteries with Taylor Dunn labels were mfg by Exide and lasted approx five years.
The key to making your batteries last is to keep the batteries fully charged as much as possible and keep the internal plates submerged with distilled water only, but do not overfill!
