If the car’s starter clicks and the engine does not turn over, this could be caused by several things. The most common cause of clicking when the car is being started is a low battery. Most people would assume that the starter is bad if it only clicks, but low-voltage can cause the starter to make this sound.
The battery is the heart of the starting and electrical system. If the battery has been drained or has a weak cell, this can cause the starter to only click. Many times the battery could just been drained due to a door left slightly open, making the dome light stay on. Other times a vanity light or a phone charger could be left on. During my time as a master auto technician, I’ve had a trustworthy co-worker close me up in the trunk so I could make sure the trunk light went off when the trunk was closed!
In order to test the battery it must have a good charge. If the battery is not charged completely the tester will indicate that it needs to be charged before testing can proceed. The first step when checking the starter and electrical system is to make sure the battery is in good condition. Most parts stores will check batteries for free. Once it’s determined the battery is good the rest of the system can then be checked. Loose or corroded connections can also cause a clicking and for the car not to start.
The starter solenoid on many Ford vehicle’s is on the inner fender well, on most other vehicles the starter solenoid will be mounted on the starter. The clicking that is heard many times is the solenoid. But low-voltage either from a drained battery, bad battery or poor connections can cause this. Most of the time if the vehicle can be jump-started the starter is okay. This would also indicate that the connections to the starter are good.
Once the vehicle is running the alternator output can be checked. If the alternator is not charging the battery, it will be drained during the process of starting the car and driving. When the alternator is checked, the voltage and amperage output can be measured. Also the diode pattern will be checked to make sure the alternator won’t drain the battery when the engine is turned off. In the past do-it-yourselfers could disconnect the battery while the vehicle is running to check the alternator, if the car kept running the alternator was good. Doing this on computerized vehicles can be harmful. If the battery is disconnected while a computerized vehicle is running the alternator output can increase sharply allowing excess voltage to spike the computer.
When purchasing a replacement battery the cold cranking amps required for the vehicle should be checked. It’s best to purchase a battery with more cold cranking amps than the minimum required. Also when purchasing a battery you should consider if you want maintenance free or not. If the battery is hard to access or has a cover then a maintenance free battery is preferred. For instance on some Chrysler Sebrings and Chevrolet Corvettes the battery is located behind an inner fender and on a Chevrolet SSR. the battery is located underneath the bed where the spare tire would normally go. If installing the battery yourself be sure to notice which side is positive and negative in case you were sold the incorrect battery.
The terminals should be free of corrosion and should tighten up well. Sometimes especially on import vehicles the battery terminals will be very thin and can have hairline cracks causing a poor connection. Avoid forcing the battery terminals on by tapping them. The battery casing can be damaged causing a leak, if the battery acid seeps out it can cause fast corrosion. If the battery terminal bolts will not tighten, then replacing the terminals is recommended. When the connections are tight you should not be able to twist them by hand.
This rapid car charger hosts up to five devices and powers them up twice as fast as your average wall charger. It caters to a car full of people—or your ever-multiplying devices (think: GSP, phone, iPad).
The 5x version has two ports that use intelligent recognition—they read your device, then pull the most possible power accordingly, sending out anywhere from two to 2.4 amps. The remaining three ports charge at a steady two amps (which is double that of an average wall socket).
If you simply want quick charging for one device, their 1X version uses the same rapid charge technology to power you up twice as fast.
So whether you’re traveling solo or in a packed car, everyone’s device can get a full battery, fast.

Many of us film-makers, videographers, and photographers find ourselves needing AA batteries to power our lights, audio gear, or flash units. And rechargeable batteries can be pretty unreliable. I’ve found that eneloop batteries seem to hold their charge longest. And I’ve also found that this battery charger by La Crosse Technology can help keep your eneloops in top working condition for a good long time.

The OPTIMA Digital 1200 12-volt battery charger and maintainer was designed to enhance the performance and lifespan of OPTIMA batteries, as well as all other flooded and AGM lead-acid batteries. This video explains some of the unique features and functions of this product.

What’s the best charger for an Optima SpiralCell AGM battery? What’s the best method for recharging a battery? Find out in this informative video from Optima Batteries.
You’ve learned that with minor adjustments, you can keep your vehicle running smoothly. A tweak here, a new tip there, and you’ll be able to get a little more from your ride.
Here are a few tips for keeping your lead acid battery performing at its peak. There are also a couple of things to keep in mind when maintaining your Absorbent Glass-Mat (AGM) battery, including OPTIMA batteries.
Newer chargers keeping up with battery technology. Many newer battery chargers, or Smart Chargers, have microprocessors that collect information from the battery and adjust the current and voltage accordingly. Some have different settings for charging wet cell (flooded), gel and AGM batteries.
Battery performance limiter: sulfation. All lead acid batteries can experience sulfation—the formation of lead sulfate crystals upon discharge. Look for a charger with a de-sulfation mode to help condition your battery and keep it performing at its best.
Low and slow is best. A low amp charger (1 to 10 amps) is always the best choice for charging any lead acid battery. It’s quicker to charge at higher amperage, but it also generates a lot of heat, which reduces the life of a battery, just like the raging heat of summer.
Alternators are NOT chargers. Don’t rely on your alternator to do the work of a charger.
An alternator is meant to maintain a battery, not charge it.
Batteries eventually die. Batteries are a consumable product. No battery will last forever. The goal is to consistently maintain your battery to get the most life out of it. Charging Considerations for AGM Batteries
Different chargers. Different capabilities. Although under normal conditions, most 12-volt automatic battery chargers will work on an AGM battery, the battery will only be charged to about 80 percent of its full capacity. Many newer battery chargers have settings specifically for AGM batteries; some even have separate settings for OPTIMA RedTop® and YellowTop® batteries.
AGM and gel technology differ. Remember that the technology of an AGM battery is not the same as a gel battery, which has its own charging requirements. If your charger offers different modes, select the correct one for your battery. If you use the gel setting to charge an AGM battery it won’t fully charge and, over time, it will actually damage your AGM battery.
No problem charging an AGM at 10.5 volts or greater. Under normal starting conditions, an OPTIMA battery should never experience “at-rest” voltages below 12 volts. Most 12-volt chargers and alternators have no problem recharging an OPTIMA if it has an “at-rest” voltage of 10.5 volts or greater.
The magic threshold 10.5 volts. The charging scenario for a deeply discharged AGM battery, one that’s dipped below 10.5 volts, is slightly different. Tips for recovering a deeply discharged AGM battery can be found in OPTIMA’s tech tip, How to Resuscitate a Deeply Discharged AGM Battery.
Chargers we like. OPTIMA hasn’t tested every battery charger on the market, but there are a few battery chargers/maintainers that we’ve tried and like. Some of these units have the additional capability of doubling as a battery “maintainer” for stored vehicles. Some come with additional wiring to permanently attach leads from your battery to an accessible location on your vehicle for easier hook up. You can contact OPTIMA Batteries Customer Service at
