YTX14-BS = A 12v 14a rated battery.
BS = Battery acid supplied.
The Prep:
1. Fill acid and let the liquid soak into the pleats... Over one hour first thing.
2. After that hour, charge battery per formula (see below).
3. Drain battery down to 1 to 2v, then recharge.
4. Repeat 2 more times, meaning, charge per formula, deplete battery down to 1-2v, recharge.
The Drain:
a. Use the high beam headlight filament side, and a brake light filament side for its high intensity.
b. Use jumper cables because the heavy wire will take the heat, the alligator clips off the jumpers attach to the high beam and brake light filaments.
c. If just a single bulb is used, it just means it takes longer to drain down to the 1v.
The Formula:
12N12a = A 12v 12a battery.
Move the decimal point over to the right once on the amp rated battery.
This means you need a 12v charger with a 1.2a rated charger.
This too means, you cannot use a 1.2a rated charger in a 1.4a rated battery.
Read the back of the charger before purchase. Walmart has a 1.5a rated charger and this is the one you want.
This means you literally charge the battery at 1.4a for 14 hours straight.
This means you literally charge a 1.2a rated battery for 12 hours as per formula.
The Theory:
You are chemically mixing the water and acid as if mixing oil and vinegar to make one liquid, not separated with a few stirs of the fork, or utensil of choice, in other words. So the more it's mixed, the better the reaction, longevity, etc.
Now install the battery for service after 3-times the charm.
Get it? And if you don't follow formula, more than likely the battery life is maybe cut in half. My initial prep has shown the battery can last as much as 6 years as opposed to 'wet and install' and may last 3 years.
NOTE:
Can I use a 10a charger? Yes. But... here is the deal. I walk away from a 10a and let it charge for hours on end, no. Why? The difference is boiled water bubbles as opposed to champagne bubbles. In other words, the boil size bubble will split the soaked plates and separate them. The low amp charger creates tiny champagne bubbles that ooze out of the pleats. So if the battery case gets hot to the touch, pull the plug and let the battery case cool. If say you want to run the low amp charger for said hours, then cook the solution with the 10a for 15 minutes say, then yes, you can reach the peak charge a little quicker to deplete the voltage down again.
Charged, the meter might show 13+ volts if say you pull the plug and check immediately. But overnight say, it runs down to 12.8v, this is an ideal number after it sits static hours off the charger.
