I'll be a bit more specific...
The SWL series are cheaper, but they appear to be for standby only use. In the datasheet, they do not give an actual amp-hour rating, but insted a wattage/cell for 10, 5 or 3 minute discharge. Will these be suitable for very shallow cyclic use, by that I mean less than 10% depth of discharge per day?
If not my other option is the Endurance series. These are 'long life standby' batteries each rated at 6 volts, 160Ah.
For roughly the same price, my options are:
- Ah Yuasa 'Endurance', daily cycling with 12.5% daily DOD
- Ah Yuasa 'SWL Series', daily cycling by just 7.8% DOD
What would you choose? I'm edging towards the larger capacity bank at the moment, for future system expansion and the occasional powercut. I would like it to last at least 4-5 years if possible.
I have uploaded booklets on the Endurance and SWL series below. Any help would be greatly appreciated so I don't end up wasting my time and money.
