Battery Care....

Recommended Posts

Yeah, it sure is... what do you tend to do about dischrging? Is there a timer on it or does it tend to sort itself out and you somehow know when it's done? I'm never sure when I'm next gonna use my battery so figure it's best to discharge it

the TLP is auto all the way. When it finishes discharging it'll simply trickle charge again unless you do different button clicks. Read the sheet it came with.

But if you let it trickle for too long is it ok? Or will it fry?

 

Also, is it ok to fast charge a 3000mah nimh on my TLP at the rate for a 600mah battery?

 

 

Part 1 - No it will not...well not in the short run...in the verrryyy long run yes.

 

Part 2 - Sure...why not...its no where near the 2.5 amp limit...thats 2500mah...but its going to take 5 hours to charge your pack...why would you want to charge it at such a slow rate?

They do not get damaged, but they do lose a bit more on their life time.

 

Also, the main reason to do a slow charge is to get 100% capacity, in which case the batteries should be charged at 1/10 the capacity (i.e 3000mAh battery charged at 300mA). You will not be able to have full capacity on a battery if you quick charge them (approx. 90% charge).

 

If you can, I would slow charge them to maximize their lifetime. But if your in a bind and you need a battery in 1 hour, you should be ok to quick charge.

Ok ok here comes another battery noob :P So i just got this...

 

Configuration: AA Mini Nun-Chuck

Fits: TM M4A1, TM M733, MP5SD6, MP5A5, XM177E2SD6

Tested Stock TM M4A1: 12+ hi-cap 300 round clips, 3600+ rounds!!

Capacity High output KAN 1300mah Nimh cells

High output 20amp duty!

Voltage: 9.6v

High quality 16ga Silicone leads.

Mini TM connector.

Double heat shrink

 

 

I don't know what most of that ^^^ mumbojumbo stands for :unsure: except that its a Nimh battery lol so will i need to discharge this battery too? If i do, does that discharger Tokyo Marui make ... any good? I don't want to mess this battery up like i did to 2 other Nicad batteries. ( They only fire about 30 round then die)

 

Anyone know where i could get a TLP battery charger/discharger form the US?

Since I don't have permision to edit my own post :o

 

I have two chargers, one says...

 

INPUT:120V~60Hz 6w

OUTPUT:9V- 350ma

 

The other one says...

 

INPUT:20V~ AC60Hz 7w

OUTPUT:12V DC 300Ma

 

So which one should I use?

With NiMH batteries, it is not necessary to discharge them before re-charging. You should, however, condition the battery if it is new (e.g. discharge then slow charge 3 times). Remember, the batteries life and operational life will be extended if you slow charge your battery pack.

 

This brings us to your chargers... The second one will not work unless you get a power supply that can supply you with 20V AC, which seems odd to me (perhaps you ment 120V AC?). The first one will not work since it can not charge the battery over the voltage that it can output... Also, be sure you are using battery chargers that are designed to charge NiCd/NiMH batteries. I'm not sure, but these chargers do not seem like they were ment for this application. NiCd/NiMH batteries have certain characteristics that a charger must be designed for, using something else will damage your batteries or not provide you with correct charging.

DOH! :angry: No wonder my old batteries just got hot and never charged. To be honest I just picked these chargers up from my dad's garage <_< . Anyone have any links to a nice battery charger under $50? Oh and thanks a lot for the info!

Those "chargers" you had up there seemed more like power supplies, which are definatly not good for your batteries :waggle:

 

I would check www.towerhobbies.com for some chargers. Be sure to check that the charger you get does not require a power supply, or if it does be sure to get one that will provide the correct amount of voltage at a high enough current (for the most part, a 12v - 14v @ 5+ amps will work for most chargers and most battery packs).

 

If you can, don't skimp on a charger. Correct battery care will save you in the long run, in the field, and in your wallet. :D

hi i am wondering if anyone can help me. I have a 9.6v 3000 mah ni-mh battery for my ICS mp5/a4 and i used the formula and found out i have to charge it for 14 hours but i was wondering if it would hurt the battery if i charged it for 14 hours if lets say it still had like 45% juice in it? I havent seen anything saying that it would hurt it so i am assuming that its ok but i want to make sure. And i have also read that Ni-mh dont need to be discharged. So if sumone can just clear that up for me that would be great.

 

 

 

 

Also, my friend has a Ni-cd battery for his m15a4 spc and was also wondering how to discharge it if u dont have a discharger. And what the best ways to discharge it without a discharger is.

 

Thanks

I am not sure what "Formula" you used to decide your charging time, an accurate time would depend on the type of charging method you are using.

 

If you are not using a charger with an auto-shut off (auto-peak detection) or a trickle charger than any amount of time you leave your battery on the charger will damage your battery. If you are unable to use a charger that provides the functions above, then your best bet is either to charge until the battery gets warm or test the voltage periodically to check if the batteries are charged (i.e. for a 9.6v battery, your probably looking at approx. 11v - 11.5v fully charged, but this depends on the cells used).

 

I guess my advice is if the 14hour charging time is correct, then you must decrease that time if your battery is not fully discharged.

 

As for your friend... A good way to discharge a battery is to get a small light bulb and connect two wires from the bulb to your battery (try and find a low-voltage bulb ~12V) and discharge until you can not light the bulb anymore. Be aware that you should not OVER-discharge a battery pack, keeping the discharger on the battery pack for extended periods of time will render the pack useless. While it takes quite a while to over-discharge something, just letting you know so you don't go store your battery connected to a discharger.

I have a TLP AC940-E charger. This one

tpacbat002.gif

 

It has a varaible dial on the fron of it for different MAh batteries. It states that it has a peak charge detecter on it as well. Would i be right in thinking that all i need to do is set it to the correct MAh and then wait for the light to stop flashing?

 

I've just thought about it today as i've got a new stick battery for my AK PDW (made it today) and realised i've never had to condition a bettery before. My last one was done by my local skirmish site as i asked for it to be ready when i picked it and my new gun up for a days shooting

What would happen to a battery if you charged it with a charger that was ment for less mAH. Without knowing I charged my large 8.4v 1700mAH NiCAD battery with a cheap wall charger that I believe is only ment for up to 1300mAH (Im not sure where I would find out what kind of batteries it could charge).

 

I charged it for about 10 hours. After about 9 hours the battery began to get hot so i let it go for another hour and pulled the plug. Did I do this wrong or am I just paranoid?

Just checking...

 

I have 7.2v 200mAh micro batteries (for my TM Glock 18C before anyone asks ;) ) and a charger rated at 7.5v 300mA. Following the formula posted here gives me...

 

200/300 = 0.67

0.67*1.4 = 0.94

 

0.94 or just less than an hour. Is this right or do I need to go back to school? :huh:

Nevermind, guys. Just been told my charger has a simple light on it which goes out when the batteries are fully charged!

 

Feel free to call me "NOOB" :blush:

Another newby question:

 

Just bought an MP5A4 second hand and it was listed as having one 1500mah battery and one 2000mah battery. But on the actual batteries it says 1500 NI-CD and 2000 NI-CD. Reading through this topic, aren't mah and NI-CD two different types of batteries?

 

Which batteries have I got and what type of charger do I need? :blink:

mAh is Capacity -> mAh = mili-Amp Hours

Ni-Cd is Chemistry -> NiCd = Nickel Cadmium

 

Your battery uses the NiCd chemistry and has a capacity rating of 2000 (or 1500) mAh.
