I have been a supporter of these batteries believing them to be good value. The low current ‘alarm’ battery is not an expensive item and if used for low current applications should be ideal.
On occasion I have had a customer complain that his battery has failed and they assure me they did not leave it discharged without recharging it.
In order to check the battery I take it in to my supplier and request they check it. It’s a 7Ah battery.
This is the response I get:
We have tested your battery.
On a 200W load the battery ran for 2 minutes.
You may collect your battery when you are able.
