Lead-acid battery cabinet is very tight

What causes a lead acid battery to fail?

Acid stratification happens when the electrolyte separates into layers, with a heavier concentration of acid at the bottom Common Problems Lead Acid Batteries. This reduces the battery’s efficiency and can cause premature failure Common Problems Lead Acid Batteries. Perform an equalization charge to mix the electrolyte evenly.

What temperature should lead acid batteries be stored?

All lead acid batteries discharge when in storage – a process known as ‘calendar fade’ – so the right environment and active maintenance are essential to ensure the batteries maintain their ability to achieve fill capacity. This is true of both flooded lead acid and sealed lead acid batteries. The ideal storage temperature is 50°F (10°C).

Can lead acid batteries rust?

Some sealed lead acid batteries have terminals which will start to rust in very humid conditions. Surface rust can quickly be cleaned away with sandpaper or baking soda mixed with water but if there is serious corrosion this will create an uneven surface on the terminal which could cause connection issues when attempting to use the battery.

Do lead-acid batteries release hydrogen gas?

It is common knowledge that lead-acid batteries release hydrogen gas that can be potentially explosive. The battery rooms must be adequately ventilated to prohibit the build-up of hydrogen gas. During normal operations, off gassing of the batteries is relatively small.

How do you keep a lead acid battery from rusting?

If you are in an area with high humidity and the terminals are from a metal that will rust then smear them with grease to provide a water proof layer. Sealed lead acid batteries need to be kept above 70% State of Charge (SoC).

How do you store a lead acid battery?

Store lead acid batteries in a ventilated area at 50°F–80°F (10°C–27°C). Ensure they’re charged to 50–70% capacity before storage. Check voltage monthly and recharge if below 12.4V. Keep terminals clean and coated with anti-corrosion gel. Use non-conductive racks to prevent short-circuiting and avoid stacking batteries unless designed for it.
