Hi guys,
Sorry, I know this must come up a lot, but what is a good source for T-105s delivered at this price?
Of course, other battery supplier recommendations also welcome.
Thanks, Paul

I guess you'd call them golf buggies.? Folks use them to ride around golf courses, retirement communities and other places as well.? Here we call them golf carts or golf cars.? I have no idea what a golf trolley is.
There are of course other battery manufacturers besides Trojan.? Do your homework re battery amp hours as they vary anywhere from about 180ah to 250 or so. You get what you pay for; if you can't find the capacity stamped on the battery or online somewhere, avoid it.? DON'T rely on the salesman's bull.?
Batteries are HEAVY and shipping will kill you.? Find a local supplier who buys them in bulk, which the golf car folks do.?

Even running the NiFe batteies to 100% DoD gives less
capacity than the T-105s at 50% DoD. Using a 50% DoD on the
FLA batteries also gives you a bigger reserve in case of an

You might also find these golf buggy businesses willing to sell batteries that have been previously used at a great discount. Though their capacity may be 40-60% of original, if that¡¯s enough for you, the savings can be great. My used T-105¡¯s cost me $20 each.? And as I get about 80ah out of these, the cost is about 4cents/watt-hr. That¡¯s a savings in $/wh of about 4x over the cost of new batteries. OTOH, they might only last me 3-5 more years¡ -mt

Hello,
You may want to check out US Battery company. They have many dealers and there batteries are sized similar to Trojan battery's with many gulf Cart size batteries. I have used US Batteries to replace Trojan in a electric car I had a few years ago.

I have no problem with US Battery and they DO give you a lot of options.??
One of the things you want to do when setting up for golf batteries is that they are NOT all the same size.? Some are a bit longer and the high-capacity ones are also taller. So make sure your battery box can handle the larger batteries, in the event you decide you want more power in the future.?
