Default batteries

Greetings everyone,
general question on testers, what is a good tester for testing batteries for capacity and or load. also can testers check if a battery is sulfated?
thanks.

I picked up a nice glass hydrometer at O'Reileys for $6. I also ordered a Schumacher 100 tester from Amazon for $20. They don't make a tester for 8 volt batteries but you still can use it but you can't use standard markings. That and a volt meter is all you need but honestly the hydrometer is the best tool.

thanks, I bought a hydrometer, all cells are pretty much in the red, batteries toast, but it gets me to the golf course twice so next bid purchase is batteries.

The cart itself is the best load tester. Hard start draw is 200-300 amps. Get an in-dash voltmeter, you'll be able to monitor the new batteries for their longest possible service life & have a built in load tester.

i installed an in-dash voltage meter yesterday, now i need to learn how to use it, i suspect i have bad batteries (2009)
i charged my cart last week and have driven it maybe 500 yards since
voltage is at 47.8 volts at rest, drops way down when i take off

so is there a thread on how to make optimal use of your in dash voltage meter?
is there a voltage for when i should hook up the charger?

Default Re: batteries

The way I load test golf carts is just put my meter on batteries and hold brake pedal while pushing gas pedal. NOTE...DONT DO THIS WITHOUT GOOD BRAKES! And dont push pedal all the way down because you will overpower the brakes with good batteries. But thats the idea and you can see what the voltage is dropping to without moving the cart. And also know that all those digital voltmeters are NOT created equal. Many of what they are selling on ebay and other places do not match up with a regular voltmeter so I would use sponsors or credible vendors if you buy one of those.
