Frequently Asked Questions
Preventing Thermal Fuse Burn-out
Please read this if you are attempting to charge and maintain multiple batteries in series and/or parallel, and you are using our 24 Volt 2 Amp BatteryMINDer model # 24021, or 36 Volt 3 Amp BatteryMINDer model # 36131.
It is extremely important that you determine the state of all batteries in your application before attempting to recharge and desulphate your batteries. Failure to do so may result in overcharging, or causing the BatteryMINDer to overheat and burn out voiding your warranty. (See BatteryMINDer instructions: Maintaining Multiple Batteries on page 4, and Note: Desulphate-condition on page 1.)
- Q: Why is it so important that I check my batteries in my application?
- A: If one or more of the batteries will not take full charge, the other batteries will overcharge causing them to boil out and sulphate. This may cause your BatteryMINDer's thermal fuse to burn out and voids your warranty.
- Q: How will I know if some of the batteries are being overcharged?
- A: If the BatteryMINDer's green connected (top LED) does not flash within 48 hours, check the voltage in each battery using a digital voltmeter. The voltages should all be the same. If they are not all the same, try to desulphate them using a 6- or 12-volt BatteryMINDer, or replace the battery.
If the green connected LED begins to flash within the 24-hour time period, test each battery with a voltmeter. All voltages should be the same.
