Another thing, is so called short trip driving being a battery killer. While short trips do not have the time required to charge a battery fully, it does not take very long at all to return the energy that was used to start the modern fuel injected engine. I did a test. I charged my battery...

Frustration growing. Any time a battery is discharged, it is sulfated. The longer these sulfates are allowed to remain and occlude the porous plates of the battery, the harder they become and the more difficult them becom when attempting to redissolve into the electroyte when charging. The...

Frankly I'd be surprised it your battery tested bad enough on Battery+'s tester, whichever product they use, being carbon pile load tester or impedence tester, likely both, to actually replace the battery. That drok 5 digit voltmeter I linked, if you put that or something similar( sampling...

Voltage is electrical pressure. A 12.8v battery hooked to a charging source, which only seeks 12.8volts, there will be no current flow. No amps will flow from charging source to battery as there is NO difference in electrical pressure between source( charger) and load( battery). The charging...

One more thing to keep in mind, is while it takes a long time to truly fully recharge a battery, this time assumes the battery is ebing held at charging voltages well above float voltage. many modern vehicles try and keep the battery at ~ 80% charged. The alternator is basically turned off by...

Flooded battery float is usually in the 13.2v range, absorption voltage anywhere between 14.4 and 14.9. I could find and post links, but I wont, showing various deep cycle flooded batteries recommending these voltages with very wide ranges. All of them are for a 77f battery. Some say to add more...

If you have a bucket that is nearly full, dos it matter if you use a 1/2 inch hose with 30 PSI, or a 3/4 inch hose with 35 psi? The 25 amp charger will only charge from well below 85% state of charge, to 85% charge faster. I dont know what Noco or C teks 'repair' mode actually does. I'd...

There is no proof that there is anything wrong with your battery(s). Smart chargers are not really smart. They largely follow a one size fits all algorithm, and the rest of the effort is expended in extra special marketing claiming how great they are. On this forum, like many products, they...

The other day My dog started barking far more furiously at the door than usual. Curious as to what she saw, I had a look and was like, dang that is the largest most beautiful house cat I've ever seen. Then I saw the short tail and I realized it was a bob cat. My dog when it sees a regular house...

Trying to judge the health of a battery by what some charger is doing, or not doing, is not wise. Do you know how much amperage the battery is accepting at the voltage the charging source is holding it at? Do you know how much voltage the battery is able to maintain when starting the overnight...

Thanks for input. My Uncle has a lathe, but was not feeling well, and that round tuit escaped us. I've not needed to generate anywhere near the 240 amp potential of these two alternators, and have done nothing further regarding the belt(s) or mimatched pulley. I did drive cross country twice...

I've been using and comparing all three of my more powerful Headlamps, often. The Rantizon Sofirn d25 clone, the Armytek Wizard C2 pro max warm, and the Sofirn HS40 with the warmer of the two LED offerings. The tasks have been worktable, Underhood/under vehicle, or walking my Dog. Walking the...

My first experience with manual transmissions was an early 70's Cub Cadet riding lawn tractor, whose brake pedal and clutch were one. Had to release it slowly in order to not tear up the grass, and raise the throttle level. In winter time it Dad and I would install the plow and chains, and I...

A charger is basically expecting the amperage it applies, to raise the voltage up to a limit. usually in the 14.4 to 14.7v range. It also expects once it this amperage applied achieves the voltage limit, the amperage required to maintain the battery at this constant voltage will keep tapering...

While there has always been complaints about the next generation, never before has social media existed. So many people today, have grown up with all the info in the world at their fingertips, and their own Digital soapboxes from which to spew their insecurity based self marketing, delusional...

The sample rate of my voltmeter is a fraction of yours, but that overnight cold reading is always lower than any subsequent restart, even when coolant temp reads at the botton upon the restart.

Nice data. Equipment envy... Was engine overnight cold? I see far different minimum voltage on warm restarts vs overnight cold when, watching my direct wired voltmeter each time i turn the key. Gotten to point i can accurately anticipate minimim voltage observed by ambient temp and engine...

There's a dysfunctional family Dynamic subtext here I don't care to share. Agreed, I could have handled it better.

I'm not going into any more detail about the decision. It's the right thing to do, I feel bad, not guilty.

Saturday she had pole position, ignored a left red arrow. Drove off with the cars going straight. Turned into opposing lane of cars going straight. Car is totalled. All airbags deployed.
