Gel Batteries Basics

In addition the gases produced during the charging process are converted to liquid within gel batteries, preventing gases from escaping. This makes them much safer in certain circumstances and very suitable for use as service batteries.

Advantages of gel batteries

• Gel batteries are virtually maintenance free as there is no need to check or top up water levels.
• This also means they can be used in applications and situations where water isn’t easily available.
• They are safer as they won’t spill when not upright or even if broken, so there is less risk of sulphuric acid burns.
• As mentioned they don’t give off fumes when being recharged so are ideal in situations where ventilation is poor.

Disadvantages of gel batteries

• The main disadvantage of gel batteries is their cost as they are very expensive.
• Their life span is usually shorter than that of ordinary batteries.
• Hot temperatures can shorten their lifespan even further as heat can harden the gel and cause it to shrink away from the plates.
