how to care for a lead battery vs li ion gel

[sharinginfos]

hi
i know that li ion you aim at staying between 80 and 20 pourcent.
for gel battery you always want to put it back to full every time you can.

what about lead battery. what is the correct utilisation?
what to avoid that lessen battery life.
how to store them for long time

also important. How to i test how much life life is in a battery , see if it is still good good for how long ? maybe it is possible to test how many amps hour they are able to deliver

thanks

Gel batteries are lead acid batteries, with thickened electrolyte, and sealed to allow operation in any orientation. Care is approximately the same. Flooded lead acid cells should be checked for water level and topped up with distilled water as necessary. If they're kept for a very long time, like in a solar or backup power installation, they may need pH testing every so often and perhaps additional electrolyte.

There's not much reason to be using lead batteries anymore. Even if their weight and maintenance aren't deterrents, they have relatively short life and quickly declining performance compared to say lithium ferrophosphate. Given that 4S LFP and 6S lead-acid can use the same charging infrastructure and voltage thresholds, I'd go for LFP almost any time I had the choice.

but are there rules like never let it go to 0 volt?
always full discharge before doing a charge?
how to care for it

 

[fechter]

With lead-acid, avoid deep cycles. Charge as soon as you can. Leave them at 100% charge as much as possible. Bad things happen when they get fully discharged and stay that way for any length of time.

 

[Chalo]

For lead-acid batteries:

They should always be fully charged unless they're discharging or recharging. That means 13V or more for a resting healthy 12V battery (becoming lower as the battery wears or ages out). Don't let them sit around in a partially discharged state.

10V is as low as they should ever go. Less than that causes some degree of irreversible damage, depending on how low and for how long.

You'll get many more charge-discharge cycles if you limit depth of discharge to 50% than if you go deeper than that. Discharging to 0% state of charge every time will wreck the battery's capacity and performance in just a handful of cycles.

Low current trickle charging will prevent self-discharge from draining the battery over time. Best is probably to put a trickle charger on a timer, so it turns on for an hour a day or so. Even very slow trickle charging will gradually vaporize water from the electrolyte and deplete the battery, so just enough to keep voltage topped off is better than trickling all the time.

All these helpful tips are less valuable than this one: Lithium ferrophosphate batteries are better in every way than lead-acid batteries. And they're even cheaper, in terms of usable watt-hours X number of recharge cycles, than the cheapest lead batteries.

hi ,
here are the pieces that came with the bike .
the battery is at 5v atm. i have the charger but i dont know if the red light should be on or off before charging it. anyone knows?
i imagine the battery is a 24 volt because of the charger that came with it and this image that looks like the kit i have

now i do have 2 12 volt gel wheelchair batteries in working order. I though of using them to test if the motor works.
I do have couple wires but i dont know how can i use them to plug the betteries in serie without getting electrocuted or damaging stuff.
I have an exact and cutter available. if the wire is big enough i would prefer using the red and black wire. is it possible how?

While being at it . i could not pump air into the tires with my regular pump. i took photos . what is wrong , what to do?

the kit is probably this

Is this your first time using a Presta valve? Based on the pics, you need to loosen the knurled nut on the end of the valve, before attaching the Schrader adapter and pump.

ok ill try it .

How about the questions of i want to test the motor while pedalling with 2 batteries in my back pack,.

how to use my wires to connect 2 12v battery in serie

green being wire with protection insulation
gray being i used knife to take off insulation to make electric contact.
is this how to do is there a better way?

can the wires on this pic named second drawing be used or they will burn?

 

[nicobie]

No don't do that. You need to search on google and pay attention to the picture that pops up.

hum i dont know if my yes are trumping me but it appears to be de same . blue is neg et red positive
in serie to have 24 volt(motor is 24v) . can you double check ,

and what about the wires

 

[nicobie]

Your pics show a connection between the + and - on each battery. This will cause a direct short.

Think you wrong. Think about a flash light with battery's end to end. Series is what that is.

so are both drawing ok?

also if a batterie is only able to deliver 10amps but the controller moter wants 30 amps, what will happen? does that damage the battery or it does not damage it just the motor will not have as much power as it would like?

are there gadjet to temporarily hold wire in place without soldering?

 

[fechter]

If the controller tries to pull more than the battery can handle, the battery voltage will sag down enough to trigger the low voltage cutoff. It might also make the battery overheat if done long enough.

I've used "european barrier terminal blocks" to attach wires without soldering. You put the end of the wire in the terminal and tighten the screw to hold the wire. They come in various sizes.

also if a batterie is only able to deliver 10amps but the controller moter wants 30 amps, what will happen?

Heat and damage to the batteries. Add a fuse, maybe 15A to give a little headroom, but will blow if you can't control your throttle hand.

ok and how much amp can the wire close the the pencil handle ? would they catch fire or just burn inside and no more connection if there is to much current?

Also. i received 2 lead batteries that have only worked to couple months . now at full charge they show 6 volts.
i also seen in the past people adding liquid to a lead battery. i dont know if that is even possible with the batteries see picture.
could adding the liquid restore them to somewhat usable for a little time or is there nothing to do considering they were left unattended for 6 years.

thanks and the wire question above if you have the knowledge..

Jesus Marty... If you connect a wire from the + to the - of a battery sparks will fly. Don't confuse this kid more than he already is

The picture shows a 12v battery if it now showes 6 Volt it is useless junk. Now you know why lead acid batteries are not good for ebikes.

I don't understand what you mean about pencil. I bet english is not your first language

Look at a picture of battery's connected in series. Think you will see + and - connected.

decapitalization of E. E. Cummings

It may at first seem of little import, but for a poet who paid such exacting attention to typography, it must be said once and for all that his name should be written and printed with the usual capital letters in their usual places: "E. E. Cummings.''

Let us dispose, first of all, of the usual reaction when his name is mentioned in conversation: "Oh, isn't he the poet who never uses capitals?" Even a casual look at his poems shows that of course he uses capitals—he uses them frequently, albeit not always conventionally. The same goes for spacing, word and line breaks, parentheses, and punctuation, not to mention grammar and syntax.

What probably accounts for the common misperception that he is a lowercase poet is his usual printing of "I" as "i." Interestingly, he wrote in a letter to his mother, September 3, 1925 (Selected Letters, F. W. Dupee and George Stade, eds., 1969, pp. 108-9): "I am a small eye poet." Notice that he capitalizes the first-person singular, distinguishing between the writer of the letter and the writer of the poetry. And in his letters he most frequently used the uppercase form, with his signature at the bottom in caps, thus:
