How do these batteries perform in hot climates?

Here is a chart that includes discharge information as it relates to temperature: http://vmaxtanks.com/charge_discharge_charts.pdf

The batteries have a life of 3 to 5 years. This is based on the batteries being kept in a good state of charge as well as being used in a appropriate temperature. The biggest factor that will determine the live of a battery is the temppetature. As the temp. rises the life goes down.

Ive had no issues with mine not working due to rain harming wiring. I would turn them to the off position until you can get a few days of full sunshine, then turn them back to the on position. This will get the battery a good full charge. I think they will be fine once you do that. So basically to answer ypur question, YES! They should work fine once you start getting full sun!

I keep mine in my car and it gets hot in Louisiana. As well. No problems so far. U may want to check the batteries from time to time for corrosion. Dave

I have these installed in a motorhome. I dont use them a lot but after a year they work fine. I dont know how well they would hold up being outside with the humidity.

I have used mine in temperatures as low as 20 below zero (for a string of 5 days) and it functioned flawlessly. The one draw back is the battery life is somewhat reduced by the cold temps. Hope this helps.

I like these in the motorhome, they seem to work and a lot easier than the dry-the-air containers. I just recharged my 4 yesterday and they only work with 110v with 2 prongs to plug in outside for the moisture to escape and they do get hot when charging. I bought the larger EDV500 back in Jan/13 and pluged them in just before summer and am just recharging them now so they last a long time.

Were I live definitely does not get as cold as Chicago for extended periods of time but we do occasionally dip into the single digits for a week or so at a time and during those times they have performed perfectly always coming on. We are in 30's and 20's most nights during the winter and they work fine never had any problems with them not operating in those low temps. They have worked perfectly in the snow and rain with no issues and have had them installed for longer than six months and I am still using the same dollar store batteries I put in them when I first got them.

As to my answer if you care to read this it explains how temps relate to battery types. Have a feeling amazon will not allow the link though http://batteryuniversity.com/learn/article/discharging_at_high_and_low_temperatures

Hi Grant! I don't have quantitative data, unfortunately, and I could find no numbers on the Web. We've found the life of these batteries (between charges) to be acceptable for our uses. We're not pros, so we don't go out for extended time periods and burn the batteries all the way down. We've not been caught short or in need of a charge by these items, under our use conditions. Sorry I don't have better info; all we can say is we've used them for a short while and noticed no operational difference from OEM units in our hands.

Yes. But they do not seem to hold charge as long as I expected. They will possibly have better performance in a very sunny location.

Mine have produced about 6.5 -7.0 volts under full Louisiana summer sun. In the shade they still produce about 6.0 volts and keep my batteries charged indefinitely. I rarely end up with a discharged battery in my feeders.

I think high temperatures would be considered charging it in a very very location like 80+ degrees or charging it in direct sunlight. I would take it as the advice given as NOT to leave one's cellular phone in a hot car. Heat lowers the internal resistance but this stresses the battery.

they're just like other lead-acid batteries and will lose their charge quicker in the cold and also sustain damage. i suggest you find a warmer indoor place for your battery. if you're using it at a ski chalet you can either hook a heater up to keep it warm when you're not there, or just transport it around with you. remember tho it's quite heavy

80-90 is not too bad, though the dashboard scenario is probably NOT a good idea, since dash temperatures probably move closer to 100+ degrees. It's an unfortunate fact, leading to a sub-optimal partnership, that batteries don't do well with too much heat, and solar panels need the sun. Even Li-ion and li-po batteries (which utilize less electrolyte than, say, a lead-acid battery) are affected by heat. Heat will SHORTEN the life of a battery while temporarily boosting efficiency by reducing the internal resistance (less resistance = more current). If you charge in 80-90 degree heat, try to keep your Opteka OFF the ground, if possible, maximizing air flow around it. If you continue to expose your battery to high temperatures, you are guaranteed to reduce its life.

I charge mine on the window sill of my office, where it gets only afternoon sun (about 3 hours). It stays cool, but won't charge to over 3 bars.

we have had them all summer in Utah which gets very hot. They have worked very well. Not sure about the cold yet. This is the first year they have been out however there have been some freezing days and they seem fine

I've had no problem with the battery so far. I haven't noticed any more heat generated than before. Overall a good buy.
