There's several things to try before you buy new batteries, and tho likely, they may not be completely shot.

Check and clean all posts and cable connections first. Why? See #1.

  1. Since they are dead the charger is reading zero and “thinks" there's no battery. Jump it to another battery and see if the charger will then start while both are connected.
  2. Use an outside charger for twenty minutes or so and see if there's any improvement. If so then same as #1.
  3. I'm taking it that these are lead acid because that's what golf carts use. If the batteries are new enough to be worth it… rebuilders regularly repair totally dead batteries. They take the top off; there's a way around that, but you'll have to buy a bag of replacement electrolyte for each battery. In use the metal of the plates is caused to float on the fluid by charging, and goes back when discharging..IN USE. When a battery is allowed to sit and die, these particles fall to the bottom instead and build up. When this builds up enough to reach the bottom of the plates they short and that's it for that battery… Unless you you clean it out, and here's how:
  4. “If the batteries are new enough" means if they are old don't waste your time. There won't be enough of the plates left to make this worth while. Only a couple of years? Turn it upside down and shake all the fluid out (in a Safe place please) then wash thoroughly inside with a water hose. Zero black specks left. Refill with the new electrolyte and SLOW charge to totally peaked…hydrometer at top of green, or volts at 13.2 min. to 13.8 max. OFF the charger. 6v batteries should be same with 2 connected into 12v, or 6.3 min. to 6.6 max volts.
  5. I've done this maybe 30 times with varied success…All worked, but the older the less time is left. The best gave me 5 more years.
  6. You probably have 4? Saving $120 each is good pay for this little operation.

If your batteries are completely dead they likely are shot and you need new ones. How do you maintain your batteries in the off season? If they are not on a tender they will continue to drain down. Once the batteries hit below around 12.5 volts, sulfation on the plates inside the battery starts. This causes permanent damage to the battery and once that happens they will never come back.

Protect your investment when you purchase your new batteries with a battery tender if you do not have one already. Good properly maintained batteries can give you sometimes up to 10 years out of the batteries.
