Abstract: In the following article research results for VRLA gel battery performance in the dynamic load cycle is presented. The research was conducted for several-hundred consecutive charging/discharging cycles. In the work there are presented changes of usable capacity of the battery and impact on a life-time of the battery in dynamic load conditions. There is also presented the effect of load current value on heat emission process, caused by an increase of temperature values on the battery casing and terminals. Acquired results are compared to operational conditions provided by the manufacturer. The research was conducted on two factory new VRLA batteries, which in the course of the tests were completely worn out.
