Battery Don'ts
Inspection Guidelines
Open-Circuit Voltage Test
For accurate voltage readings, batteries must remain idle (no charging, no discharging) for at least 6 hrs, preferably 24 hrs.
If battery registers below the Table 1 values, the following conditions may exist:
Batteries in these conditions should be taken to a specialist for further evaluation or retired from service.

Flooded batteries need water
More importantly, watering must be done at the right time and in the right amount or the battery’s performance and longevity suffers.
Water should always be added after fully charging the battery. Prior to charging, there should be enough water to cover the plates. If the battery has been discharged (partially or fully), the water level should also be above the plates. Keeping the water at the correct level after a full charge will prevent having to worry about the water level at a different state of charge.
Depending on the local climate, charging methods, application, etc., It is recommended that batteries be checked once a month until you get a feel for how often your batteries are need watering.
Important Things to Remember
Step-By-Step Watering Procedure
WARNING: Never add acid to a battery.
Storage
Periods of inactivity can be extremely harmful to lead acid batteries. When placing a battery into storage, follow the recommendations below to ensure that the battery remains healthy and ready for use.
NOTE: Storing, charging or operating batteries on concrete is perfectly OK.

No one was injured and it appeared there was no property damage.
Camera crews filming HBO’s “Hard Knocks” series captured the accident and broadcast it for all to see.
That included Sean McVay, then offensive coordinator for the Washington Redskins.
