Question for you Mark. For the past 5 plus years I have run my batteries until it shows on the wall gauge 1/3 full charge. At that point I change over to my other battery. Yet many posts claim that you shouldn't take them below 50%. How do you check your battery while camping (wished I asked you that at the ERU in Traverse City this summer)? I ask that because both my batteries will be 6 years old next March and still seem to be working well even though I have made it a habit to bring them down to 33%, at least according to that gauge on the wall. I know how inaccurate that is when it comes to showing the black and grey water levels, maybe the same for battery charge?

When I store my Rpod, I disconnect the wires on the negative side of the battery.
With an inexpensive multi-meter (< $10 on eBay) you can check your battery's state. Volt DC (Vdc) reading of the following indicate state of charge: 12.6 vdc is about 100% charged; 12.4vdc abt 75%; 12.1 vdc abt 50%. Batteries have something known as leak voltage. Even disconnected they can lose about 10% charge a month (lead acid battery). In the disconnected state, I recharge my battery about once a month (or as needed). Battery tender (or trickle charger), another option, I believe has been discussed. Note: Volts can be thought of as pressure and amps (Amperage) as quantity. The above testing scheme only works on a healthy battery. An unhealthy (tired) battery may read charged (Volts) but not be able to deliver enough amps.

Good to read the whole thing, but just to answer the question on how to check on the battery, scroll 2/3 of the way down to the colored chart.

I've still have my original battery for my 2017 179 (new April 2017). I do not boon-dock and I have replaced my converter once. So I am always plugged into shore power so the battery stays charged. I likely will look at replacing it next year when it turns 5, but really haven't had a single issue with it. ~PP

If the battery is performing well and if you get it tested and it is good, I don't see why you would need to replace it just because of time. It may last a few more years since you are not really stressing it.
