Battery/Alternator Tester

Does anyone have a favorite Battery /Charging System tester that they use and feel is reliable. Besides this truck I have a small fleet of vehicles, (1 SUV, 4 Cars, 2 Bikes, and other power equipment) I would like to have a reliable battery load and alternator charge, test meter. Also would like it to be affordable...not too much to ask right?
Thanks!

I think the first step is a digital multimeter. I currently have a couple of harbor freight and fluke meters available to me. Both have been accurate. As far as a load tester I am sorry I am unable to help you. I have access to a snap on unit through work and really have not used any others. Sorry.

Sounds like what you want is a battery conductance tester.

Midtronics (there are others) makes an entry level model for about a C note. Since you have quite a few to service and monitor it would be a good tool to have. Also handy if you ever decide to help someone stranded needing a jump or diagnosing a "new" vehicle problem. The standard method of testing a battery correctly is time consuming because it requires fully charging the battery then partially discharging into a carbon pile, and recharging again.

Conductance testing is a newer method utilizing a derived AC signal and gives accurate battery health in seconds and doesn't require charging before or after the test. They also have a volt display for charging system use. No sense messing around with a defective battery, so it pays for itself eventually.

Well, a $5 HF voltmeter will work too, if one knows what they are looking for. It's all good as far as that goes.

We have a D-Tac Elite in the shop. But, $4k is probably not what you're looking for.

I have a SOLAR BA5 100-1200 Cold Cranking Amps Electronic Battery Tester for road calls. Which, surprising to me works well for $40 - $70. I bought one for home as well.

The Carbon Pile Testers can be cumbersome and a pain sometimes with the short leads.
