In the standard delivery program SSB firm are lead-acid batteries and batteries SB series to the optimal operating conditions the lifetime of five years. Lead-acid accumulators and batteries SB series are available in capacities range from 0.8 to 200 Ah and are suitable for general backup purposes.
For more demanding backup purposes are specified lead-acid batteries and batteries SBL series, thanks to special design and materials used to double the life compared to lead-acid batteries and battery SB series. An interesting feature is again possible confusion accumulators and batteries SBL for a range of SB while keeping size and capacity, which can offer users twice the useful life of the backup system without interference with its mechanical design. This option is used most of the UPS, so these batteries are manufactured in capacities from 7 Ah to 200 Ah.
Between the special types of lead-acid accumulators and battery can then calculate a series SBH, which is used for some types of small UPS. Their characteristic feature is the  ability to deliver in a short period of time up to 75% more energy compared to SB.
