Poor advice about batteries!!

[Revolvor]

Saw this on Facebook today ......

Can anyone recommend a solar /auto electrician or knowledgeable Moho engineer in my area please.. West Midlands/Worcester area??

Got a system fitted, but think I've killed the batteries & want to upgrade to a Mppt controller.. got lots of great advice re batts & controller from here, but not entirely sure of size or fitting.

My local guy advised me to run the batteries really low as it helps capacity - which is opposite to everything I read here , so not sure I trust him to touch it........

Maybe the local solar installer is trying to to sell more batteries!

That one piece of advice would stop me going back!!!!!!!
Running low is probably what killed the battery??

I recall that advice, but it was long ago and specifically for NiCd batteries. A little knowledge is a dangerous thing.

I hope you pointed him at our good guy @dave newell

Why do you think youve killed your batteries? Have you tried charging them on hook up??
Why type are they??

They are not my batteries ..... I was just copying something from Facebook. It was the advice about letting batteries go flat that caught my attention!
