Rechargeable batteries perform valuable work every day in numerous areas - whether in cleaning machines, forklift trucks, safety systems or UPS systems. Proper care is crucial to ensure that they function reliably for many years.

Whether for daily or seasonal use: If you follow a few basic rules, you can significantly extend the service life of lead-acid batteries and increase their reliability. Our "Golden rules" show you what is important.

Our golden rules for long-lasting batteries:

  1. Use a suitable charger 
    Make sure that the charger and battery are optimally matched - this protects against overcharging or undercharging. 
  1. Do not forget to charge for the first time 
    Charge the battery at least 24 hours before the first useto activate its full capacity. 
  1. Avoid deep discharge 
    A discharge of more than 60 % can have a negative effect on the service life - regular recharging is ideal. 
  1. Do not store empty 
    The battery should not be completely discharged even if it is not used for a longer period of time - a minimum charge level protects the cells. 
  1. Charging with the load switched off 
    When charging, the connected load should be switched off in order to optimise the charging conditions. 
  1. Regular winter care 
    If batteries are not used for a longer period of time, e.g. in winter, they should be recharged for 24 hours at least every two months. 

Why good care is worthwhile

With the right handling - regardless of how often the battery is used - you will noticeably extend the service life of your lead-acid battery. You benefit from: 

  • longer operating time for your devices 
  • Reduced costs for replacement batteries 
  • More reliability in daily use 

Just a few simple measures help to maintain full performance in the long term.
