Charge your battery in a well-ventilated location. Select a location like a garage or large shed. Open a door or window if you can. Good ventilation is important because, during the charging process, a mixture of gases builds up in your battery, and if the battery is overcharged or shorts out, these gases may vent out of the battery.

To check the electrolyte level in a sealed lead acid battery, you should remove the vent caps and look inside the fill wells. The minimum level should be at the top of the plates, and the level should be around ½" above the plates in each cell.
To clean the battery and to perform a battery gravity test on a lead-acid battery, the following tools and items are needed: Baking soda - used to neutralize any acid on the battery''s surface. Distilled water - used to rinse the battery after cleaning and to fill the battery cells if the electrolyte levels are low.
Discharging your battery at a higher rate will increase the temperature in battery cells which as result will cause power losses. e.g, a 100ah lead-acid battery with a C-rating of 0.05C (20 hours) will last about 20-25 minutes instead of 1 hour while running a 50 amp load (remember the 50% DoD limit).
Check the battery''s water levels regularly. Sealed lead-acid batteries require regular maintenance, and one of the most important things you can do is to check the water levels. ... If you notice any of these signs, it may be time to replace your sealed lead-acid battery. Remember, it''s always better to be safe than sorry when it comes to ...

And at the other end of the scale, a lead-acid battery is considered fully discharged when it reaches 12.0 volts. Finally, to remain healthy, a lead-acid battery should be at least above 12.5volts at all times. So what can we learn here? At 12.7 volts, this battery should be healthy and ready to go.
For a lead-acid battery, the test time is approximated to be near the battery''s duty cycle. Most lead-acid batteries have a duty cycle of 5-8 hours and this is the timeline used and the end discharge voltage is usually 1.75-1.8 volts per cell or 10.5-10.6volts. ...
