Calculation Date: Thu, 13 Jun 2024 09:17:01 +0000
These results are calculated using the IEEE485 recommended practice for sizing
lead-acid batteries for stationary applications and real systems data supplied by
some of the worlds leading DC system manufacturers.
We review and check all manufacturers data before loading it into the on-line
calculator and do our best to keep it up to date and reasonably accurate. However,
we cannot control the price of lead which fluctuates on international metal
markets, nor can we control when manufacturers change their prices or systems data.
Therefore, please use this data for BUDGET pricing. For detailed design and pricing
help, please contact us - we would be happy to provide you with a free and prompt
review of your project specifications, have a preliminary discussion and help you
obtain a fixed and firm price for the most cost-effective system for your project.
