My boat has 2 large batteries, one for starting the engine (BMC 1.5) and the other for lighting etc. Whilst these have performed adequately for me over the past 12 months, they are of uncertain provenance and look to be a few years old. My question is how do you tell when a battery is reaching the end of its useful life before it suddenly lets you down? Are there simple tests that you can apply in order to get an idea of battery condition and life expectancy?

Simplest way is to get a Hydrometer. Almost any car shop will have one. Just sucks some acid out of the cells and gives a reading of the level of charge. Best done when they have been given a good charge and the main thing to look for is one or more cells giving a significantly lower reading than the rest. If that is the case the battery is almost certainly on it's last legs.

Hi Steve

I have recently had my batteries tested at Sutton Staithe Boatyard with what he called a drop tester, he climbed in the engine bay, took the tops off and and disconnected each battery and shorted the battery out using a device with some sort of meter and heat sink while checking each battery cell, result, both batteries OK, and he did not charge me for checking them although I had agreed to buy them from him if the boat needed them.

I am sure you can buy a hydrometer for battery testing for a few pounds at your local halfords

THE WET STUFF SHOULD BE ON THE OUTSIDE OF THE BOAT!!

Hi Steve, if you are starting to use more water than you have in the past that is also a sign that they are on their way out. at least thats what my local garage told me.

Batteries rarely go down without some warning but as has been previously mentioned, a rapid discharge AKA drp tester is va really good way. On a boat a god condition indicator is worth fitting too.

Trying to answer the original question, you know when they are on the way out when they fail to maintain a charge for very long, hence the drop tester which demonstrates whether the voltage is maintained under load
