Marine Battery and Electrical Log
Track battery voltages as a series rather than a single reading, so a bank that is dying is obvious well before it strands you.

What this sheet is for
Spot the weak battery, or the cell that keeps reading low, before it drags the pack down.
Who it is for
Golf clubs, cart fleet mechanics, caravan parks, estates and private owners with a flooded lead-acid battery pack.
How to use it
- Copy the full-charge reading, temperature correction and equalising trigger from the battery maker into the boxes at the top.
- Number the batteries in the pack once, and tick each one as it is topped up after a full charge.
- For hydrometer readings, note the pilot cell temperature and write each cell's corrected reading.
- Work out the spread for each battery and log any equalising charge on the back.
What is on the sheet
2 pages, in this order:
Page 1
Printed under the title: Every battery in a cart's pack topped up after a full charge, then cell by cell hydrometer readings, so a weak battery or a neglected cell shows up before the cart stops halfway round.
The battery maker's figures, not ours. No specific gravity figures, voltages or water levels are printed: they differ between battery makers and models. Copy the full-charge reading, the temperature correction and the spread that calls for an equalising charge from the maker's literature. Electrolyte is acid, so wear eye protection and gloves.

Questions
Why are no specific gravity figures printed?
Because the full-charge reading and the temperature correction differ between battery makers and electrolyte strengths. Copy them from your battery maker's literature so every reading is judged against the right figure.
Can I use this for lithium or sealed batteries?
Not the watering or hydrometer parts: sealed and lithium packs cannot be topped up or read cell by cell with a hydrometer. It is for flooded lead-acid batteries with removable vent caps.
