38.1V on day 3

[Gr8hntr]

I'm at 38.1v on day 3 after last charge .. does that sound about right and being hunting season don't open till September it will be stores a while ... what number am I lookin for and when to recharge
thx

For batteries out of work, 37.8 or lower gets a charge from me. This is where stagnation and sulphation begin to get a grip.

Thx scottyb !!
how many 10th does a pack normally drop per day ?

[JohnnieB]

General rule of thumb is that deep-cycle lead acid batteries loose about 1% of their SoC (State of Charge) per day, but some batteries self-discharge faster, some slower.

The relationship between Open Circuit voltage and SoC is not linear, so the fraction of a volt they loose per day when nearly at a full charge is different than the fraction of a volt they loose per day when they are partially discharged.

Here is a SoC vs voltage table for Trojan batteries and their clones.

6 days after charge
this is my pack numbers ... are they ok or what do I need to do lol
the + and - are the ends of the pack and numbers show how they sit in cart ... batteries are 2 years old
thx

Your batteries look okay for having sat for 6 days.

While your cart is sitting unused, you want to recharge the battery pack before it decreases to 70% SoC (37.1V), or sooner.

If the cart sits unattended for months at a time, you may want to invest in a charger that float charges.

Thx Johnnieb
yall guys here are such gr8 help to us newbies.
I store it in a heated and cooled garage that I turned into the man cave lol ... it does sit most of the summer but looks like if I keep a check on the volts each week I should be fine

Depending on the charger, just unplug from the cart and replug weekly, or at least several times a month. If it's unattended - such as a summer or winter home, get a charger that automatically goes into float.

I think you are asking for trouble ... If you do not get a charger with a float option .. Eventually human error wins and you let the voltage on pack get too low .. Invest into a good charger like a DPI Accusense .. And plug it in and forget about it till fall ... Prob check once a month for water level .. And that's it

This is the man cave .. its so accessible I check it everyday lol
