Battery "warm up period"

I'm looking at getting a set of 6V's and I understand that there's basically a break in period (industry calls it a warm up period) before the batt achieves it's full capacity. Trojan says this can take as long as 100 cycles! In our application the batteries will rarely be discharged. We only dry camp once or twice a year but when we do, we really need good battery power.

Is there any way to speed up this break-in process? Is there an exercise we can put the battery though that's not detrimental to it?

Thanks in advance,
Scott

BTW, I know about the 50% rule. :)

Hi Scott,

Add a modest solar system.

There is so little difference between the capacity of two new, fully charged GC2 6V's and ones that have been cycled, that it is insignificant to a typical RV user. The most important thing to remember is to charge soon after discharge.

If you want to get accurate about battery SOC, a hydrometer is the tool of choice. After just a few cycles, establish a base-line SOC and everything after is measured against that. You will see the SOC rise from that baseline as you get some use from them.

Some battery info........LINK

Some dry camping in driveway to lightly cycle batteries?

Per Trojan
A new battery will not deliver its full rated capacity. This is normal and should be expected
as it takes time to “work the battery up”
• Trojan’s batteries take between 50 – 100 cycles to work up to providing full, peak capacity
