You supply all the data. We only process what you supply.
In plain terms: every answer here is worked out only from the figures you enter. We add no information of our own — nothing that couldn't be derived from your own numbers.
Some battery calculations are also subjective or ambiguous, with no single "right" answer. That's part of why we don't guarantee any result, and why you should check anything before relying on it.
Enter each battery's specs as labelled. Everything shown is a calculation based on the values you supply; we don't guarantee the accuracy of any calculation.
| Metric | A | B |

Computed from user-supplied figures. Two gates, independent: the battery passes only if its peak current ≥ your demand AND its peak duration ≥ how long you need it.
These terms govern all use of this site, and expand on the notice shown when you enter.
1. User-contributed, unreliable data. All data on this site is contributed freely by its users. We take no ownership, authorship, or guarantee of any of it. We regard all information here — including every calculation, figure, or result derived from it — as unreliable.
2. Not manufacturer information. We provide only a platform and a fixed format for users to share and compare data they choose to supply. We do not represent that any of it is manufacturer-supplied, and it must not be treated as if it were.
3. Your responsibility. Anything you take or use from this site, and any decision or action you base on it, is solely your responsibility. We supply the tool; how you use what you take from it is on you.
4. Contributors and accuracy. We do not hold contributors to account for the accuracy of the data they supply, and contributors give no guarantee of it. This is deliberate — it is why all data here must be treated as unreliable.
5. Risk and liability. You use this site, and everything on it, entirely at your own risk. To the maximum extent permitted by law, we accept no liability for any loss, damage, misunderstanding, or underperformance arising from it.
6. Governing law. Nothing here excludes rights that cannot lawfully be excluded under the Australian Consumer Law. These terms are governed by the laws of Queensland, Australia.
