spare battery

[gray198]

I have a Freego Eagle with a 17ah battery. This is about 4 years old and I have absolutely no idea how many miles it has done. Has always been stored in dry garage. Also have Juicy folder with 10 ah battery not being used at moment. I am looking to do a longish full day ride around canals and trails so reasonably flat probably about 40 miles.Theoretically my battery should be up to this but not sure how much it has deteriorated, so am wondering if I could carry the Juicy battery and use it as backup. I realize that I will have to drill a hole in slider bar to accommodate it but other than that have no idea whether it is suitable. Both are the silver case type that sit behind the seatpost. Any advice on how to check and feasibility much appreciated.

regards gray

Two things: Firstly, does it fit on the pins at the bottom? Secondly, do the two slots in the battery have the same polarity. Check that with a voltmeter. If both answers are yes, go ahead.

There's one other thing: When you lock the battery in place, the locking pin has to go into a hole in the metal strip, so you'll have to drill a hole for the lower down Juicy one.

thanks d8veh. Will check the pins. Am assuming by polarity you mean + or - . Will the markings on battery be accurate or would a check with voltmeter be advisable I have one (screwfix type)but not quite sure how to use it, and as you say I will need to drill a hole to locate the battery. Thanks for your advice

Check the leads are in the right holes first. Black should be in common, red in Volts/Ohms/mA.

Stick the meter on the 200 Volts DC range, and test by putting probes across two terminals. If the result shows negative, then you have the leads the wrong way around (this won't harm anything). When it shows a positive result, the red lead is on the pos terminal.

If you don't know how to set the meter up, post a pic and we will let you know.

Thanks Alan I'll check it out

It doesn't matter how you have your probes. All you need to check is whether both batteries are the same.

It matters that they are in the V, not A terminals though!

The shorter, Juicy battery will fit the pins at the base but will not slide down the taller, Freego battery rail. The top of the battery will meet the rail, preventing the battery from being pushed fully home onto the baseplate.

You could, if you wanted, cut a groove into the black top of the Juicy to allow the slide rail to pass, but since you're trying to sell that bike you might instead like to swap over the rails on the bikes.

Then you'd be able to use the shorter rail from the Juicy on the Freego, allowing both batteries to use the same rail. The Freego battery would not be able to lock into place - but you'd be able to switch it on.

I have looked at both batteries and they do indeed both look to have same connections and polarities. I have not checked with meter . Can't work out how to. Here are some pictures if anyone can help.

Sorry about all pictures.Don't know how to get rid

Put the black lead in the whole marked com. The red one in the V hole on RHS.
Turn the big knob until it points to DC volts (10 o clock Ish) ac is wiggly line dc is straight lines. then put the leads into the battery bases. The readings should be about the same. It's important that the +/- readings don't change. When the connections are in matching battery holes.

Thanks d8ve I'll have a look at that tomorrow

And you need to switch the battery on with the key.

Thanks old Bob good point

The polarities are the same. You don't need to worry. Just swap the rail on the freego with the one on the Juicy (you'll need to drill a new hole for the fixing screw). Then both batteries can be used on the Freego.

Bob thanks for that. I'll try it and post how I get on
