How Do You Check Battery Health? By testing it, of course! But any test’s validity is influenced by the battery ’ s true state of charge . Use a hydrometer on nonsealed batteries to determine state of charge . All six cells in a 12-volt battery must read the same.

TIP 3: Always purchase a maintenance type battery (w/ filler caps), if you plan to properly maintain your battery and are not concerned about locating/operating the battery in a TIP 12: Always use an accurate digital voltmeter or similar device to determine your sealed batteries true state - of - charge .

By testing it, of course! But any test's validity is influenced by the battery's true state of charge. If it has just been recharged or the engine has been running with a normally functioning alternator, the battery may build up a surface charge that falsely indicates it's strong. It may be sufficient to crank an engine so it fires the first time, yet after an overnight cool-down, the charge dissipates, requiring the car be jump-started the next morning.

We Hear: Updated BMW i8 on the Way with More Power

  We Hear: Updated BMW i8 on the Way with More Power The BMW i8 hybrid coupe is reportedly due for an update that will result in more power and a revised battery pack for added range. The report comes from BMWBLOG, which claims the hybrid system’s total output will be rated at 372 hp, up from 357 hp. It’s unclear where the added power will come from. In its current form, the i8's 1.5-liter turbocharged I-3 makes 228 hp and 236 lb-ft of torque and is supplemented by a 129-hp front motor along with an 8-hp rear motor. BMW claims the 2017 i8 goes from 0-60 mph in 4.2 seconds, so expect that number to drop a tad with the revised powertrain.

Determining the proper depth of discharge for your battery and how to know when the battery reaches that point. Once you determine the accurate voltage, how does that relate to battery state of charge ?

Always remove the surface charge before testing. Let the car sit overnight with the negative cable disconnected or turn the headlights on for 10 to 15 minutes and then wait five minutes for the battery to rest and recover.

With surface charge removed and assuming the starting circuit is up to speed, you can get a pretty good idea of a battery's condition by disabling the ignition and using the starter as an expedient load-tester: The engine should crank for at least 45 seconds without any cranking rpm decrease.

Traditionally, the definitive test for nonsealed batteries is checking their cells with a hydrometer. You must directly check the voltage on a fully sealed battery; as with any fully charged battery, it should be 12.6 volts (engine off, surface charge fully dissipated). If in a discharged state but still capable of being recharged, most sealed batteries should recharge at near the maximum rate on your charger. If a battery won't begin accepting a charge after 30 minutes, it's junk.

  First Volvo EV Will Have Range of at Least 250 Miles, Cost $35-40K <p>CEO says range is key to success</p>Speaking to journalists at the Geneva Motor Show, Kerssemakers said the upcoming EV will have a starting price between $35,000 and $40,000, and a range of at least 250 miles.

One of the advantages of a flooded lead-acid battery is the ability to quickly determine the battery ’ s state of charge . 1) Make sure you are in a properly ventilated area and that you are equipped with safety equipment such as gloves and eye protection.

RV Battery Savvy To properly maintain and extend the life of your RV batteries you need to have a basic understanding of what a battery is and how it works. The size of the lead plates and the amount of electrolyte determines the amount of charge a battery can store.
