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.

This charge method maintains the battery ’ s state of charge until such time as the battery is required to support the load. It is important that the calculation to determine charger size be followed with a certain amount of discipline since when properly applied it provides for the least amount of wasteful

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.

4 Determining Battery Depth of Discharge/ State of Charge . . . . Battery DOD (in percent) is the opposite of battery state of charge . Normally, a properly charged , Marine/RV deep-cycle battery ’ s efficiency improves slightly after the first 10 to 20 cycles.

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.

Yes it is true that your natural Smartphone battery life diminishes with time as you continually use it, but how well you use it is also an important factor in determining how durable your If you use them in charging your batteries , they tend to weaken your batteries with time rather than extending them.

Determining the proper depth of discharge for your battery and how to know when the battery reaches that point. This throws off the " true " voltage reading and can render it inaccurate for the purposes of finding the battery ' s state of charge .
