Bought portable hybrid Versa-Lite - now what battery to buy?

over 5 days?

Andrew

Yes, if you reconnect the 10ah battery to the Aux battery system as I've stated.
The 10ah battery will last indefinitely while the Aux battery system is realistically charged above the voltage of the 10ah battery.

In the 5 days I'm sure the vehicle will be used during the day, this will recharge the entire battery system including the 10ah battery too.

Too many assumptions of the OP's situation for my liking. :)

I didn't think a battery charges all that well from <13.2V power source? Happy to be corrected on this information.

Andrew,
my only assumptions are the light will draw ~1ah, and will be used ~4 hours per night.

I then assume the OP will do as I said, and connect the 10ah battery to the Aux battery system each morning.
The voltage will then equalize in all the batteries wired together, I would expect the small 10ah battery to accept charge from a ~100ah system quickly.

I would expect the vehicle may be driven somewhere, maybe to go fishing, sightseeing or similar, or even just to recharge the Aux battery system which I would think runs a fridge and it would need recharging anyway.

If the OP believes 10ah capacity is too small he can always get a larger sealed battery.

I often run my fishfinder/gps for more than 5 hours daily from the 10ah battery and it sometimes runs 2 x days before getting a recharge, it uses "10w @ 12v"

Remember, during the day when not in use and not connected, the voltage will 'return' slightly due to recombination of the battery acids.
In other words, when actually using the light the battery may go down to 12.1v (example only) just prior to the light being disconnected that evening, next morning the battery voltage would be higher than 12.1v

Don't forget the more important assumptions that they indeed have an aux battery system, together with the assumption that they will use the vehicle in that time.

Mainey's battery looks like the common 7Ah gel cell. I use one of these for camplight and running the occasional shower. In practice its good for about 3 nights running a fluoro (you don't need it for 4 hours - usually turnit off after dinner and then the stars and moon do the rest.

They won't recharge unless hooked into the vehicle's electrics and the vehicle is running.

Central Coast Timmy,
You need a *fully sealed* battery with battery posts that are suitable for your use, as I'm not home at the moment I can't go out look at my battery 'brand' but if you go to a specialist battery store I'm sure you will find they have a reasonable range of 10ah to 15ah sealed batteries.

I only use a (14 year old) Projecta Tradesman 6 Amp charger with a "BM140" switchable lead acid/gel, Charge controller hard wired to it so it can remain connected 24/7 if required, all up probably about worth <$150, however Ctek would probably be a better charger technically, everyone using them will be able to tell you why :-)

I've only used my Projector charger with other peoples batteries, because I've never had a low or flat battery, as they are all charged and maintained by the Solar system.
