Kind of like buying harbor freight tools. I often will accept that I spent more than I needed to, but the warm and fuzzies are priceless, but when I do let my limited budget influence decisions, I often do regret it. This can push a lesser battery over the cliff edge, the higher quality battery will be damaged, lose some capacity, but stands a far better chance of having many more cycles left in them. My Vote is for the trojan's Not only is longevity a factor, and this is directly related to how well/often/quickly they are fully recharged, but they 'might' also be easier to fully recharge, requiring less time at 14.8v for specific gravity to max out.Īlso consider the ability of such a battery to rebound from unintentional abuse, like being drawn down below 10.5 volts for any period of time. more of a starting battery/ marine battery, Kowtow to walmart's price point type company. I do not believe they are well known for their deep cycle blends. I think The 6 v GC-2 at sam's and Costco now are made by johnson controls. Some rough calculations I did showed the T105 would have to last 7 years to be the same value as the sam's batteries if they last 5 years. Right now I am scraping by with a small starting battery.
I can't go any bigger than a 200w system on my van so a pair of golf cart batteries should be more than sufficient for a long while. My energy consumption will be based on what I can replenish so it is likely rare I will take the batteries below 80% until my solar gets upgraded.
TROJAN T605 VS T105 UPGRADE
I am currently running 100w of solar but will likely upgrade to 200w in the future. Just the dollars and the expected lifespan. But are they really worth the extra cash? The sam's club is let's say $70 cheaper, essentially the same in regards to capacity and size, but is more likely to need warrantied, which would mean driving round trip again?įor the sake of this decision, weight, size, capacity are not factors. The Trojans are obviously the better battery and have an authorized dealer here in town where I am stationary for the foreseeable future. Sam's club GC2 batteries, roughly $180 but would cost an extra $20 in gas round trip and potentially some fast food.
Trojan T105s,roughly $270 for a pair just across town Alright so I need real batteries but am left with the the choice,
