Dual Battery Options and Fitting

[syncro91]

I used these guys, big range, and the 120/130 fit under my seat snug.
Quick delivery and decent price.

Was this the one you selected at looks like 220mm high?

I noticed that too, even the 80Ah version is 220 high. Not sure it would safely fit under seat, but could be wrong.

I believe it was as was no height difference between the few if I remember right , but it literally just fits inside the barn seat storage area will send a photo if you like - previous photo further back in the thread

Fits in by a couple mm it looks like!

I think my 15 year old Pirahna Solar controller is dead. I installed the new 2nd battery and 100W solar panel a couple of days ago. I tested things today while parked in sunshine - battery was over 15volts and there was 4 amps going to battery. Solar controller had a yellow light on it which means only tricle/ float charge should be going to battery, but I reckon the controller is stuffed.
I have since disconnected the panel to preserve the battery.

It might explain why the previous optima & stock leisure battery both died....

What ya reckon?
Should only charge at 14.3-14.5, and float at 13.7 or so.

Hi Hoddy, all new batteries can be charged with up to 14.7v and will not be harmed by this voltage level if maintained for short periods of time, once the battery is fully charged, like while driving.

Unlike when driving ( shorter charge times ), with solar charging, because it is likely to be for long periods of time, each day, then it should go into float mode and no higher than 13.8v, once the battery is charged.

The only way your battery could be drawing 4 amps at 15v from a 100w solar panel is when your battery is already fully charged and is therefore being overcharged. Definitely time to look at a new solar regulator.

Yep, have ordered the SunSaver Duo which will also charge the main/starter battery.
Also got the remote meter to keep an eye on things.

Hmm... or the battery itself is faulty.

[drivesafe]

Regardless of the condition of the battery, because the regulator was indicating it was in float mode, it should not be supplying anything above 13.8v, not 15v.

Mind you, the battery would eventually be stuffed if left on a charge voltage that high.

BTW, while it is rare for a solar setup to cook batteries, unlike the bogus claims that you can overload an alternator and burn it out, it is actually commonplace for battery chargers and DC/DC device to cook batteries.

This is something an alternator never does.

So with these bogus claims you talk about, one would assume you are a qualified auto electrician or electrical engineer?

So are you?

Or are you just a salesman being bias towards other charging technology that competes against your product...
