12V 35Ah battery is used in many different applications like wheelchairs, scooters, Uninterruptible Power Supply (UPS), lawn mower, emergency lights, and security systems and also in solar applications.  Generally SLA battery design life is about five years at 25 C or 77F.  When the temperature of operation is high then the battery life will be reduced.   

Life improving Tips for UB12350 12V 35Ah battery:

The capacity of SLA battery will increase with temperature and will have reduced capacity at lower temperatures.  SLA batteries have self-discharge.  When left without charge they slowly discharge.  Leaving the battery without charge over a long period of time can damage the battery permanently. Also leaving the battery under discharged conditions for a long period of time will damage the battery permanently.
