Checking Batteries - somehow...

[sailted_60]

Hello,

I am looking for a way to check my batteries as I can't get down atm.

Has anyone used anything that I can get fitted that doesn't take too long + works without Victron/Mastervolt?

Cheers

Hello and welcome

Are you on the hard, in a marina or mooring?

Unless you or somebody has physical access and can install a monitoring device then it is a guessing game and will depend on the condition of the batteries. In the past I have left the boat for up to three months and returned to find them at 12.5 volts.

My tactic was always to give the batteries a 24 or 48 hour charge in December and again in April. Seemed to work OK and took less than 1 kWh from the mains each time.

I left my batteries disconnected forty four days ago after charging them. Another example maybe of why marinas should allow a short visit with SD measures to protect our assets and pay a donation to the NHS. No disrespect to marina staff but each boat has it's quirks that only the owner understands.

Given that someone needs to get on board anyway....

They could simply take a multimeter with them and take a reading.

And repeat every couple of months.

We installed this system just before lockdown and can confirm it works very well.

Cheers guys,

That chargemetrix looks good for what I need thanks MartynG & alexincornwall!

I'm really glad I took home my batteries just when this lockdown started to look imminent. They are currently reading 13volts!

You could look at Boat Vitals. I know the guy who designed and built this kit and he used to sell this stuff at really low prices.

I don't know what he charges now but worth asking.

I'm surprised that no one has suggested fitting a smallish solar panel.
