TLP 4000 not fully charging
 

Howdy good docs,

I bought a TLP 4000C off ASC a month or so ago, and since then, I didn't really have time to charge my bats to full power. Now, before going to a game, I plug one of them, which is an NI-Cd 8.4V 1200mAh in, and charge it up @ the lowest setting, which is 0.5A. Alright, everything's fine. Note that I didn't use the discharge function on it before charging.

After an hour or so, the battery's not even warm, but I guess that's normal, since i'm only charging it at 0.5, I plug it up to my gun, and I notice my motor is running at a much slower speed than usual. I meter my batt's voltage, and it's at 7.39V.

I plug it back in the charger again, then half an hour later, it decides it's full. Now, it's even lower than it was! 7.33V.

I say screw it, take the wart-charger, until it's warm. I get 8.04V out of it. Six hours later, it's still at 8.04V, so it can hold a charge.

Is that charger borked, or is there something i'm not getting here?

Check the fuse.

Took it out, with great effort, but, brand new
Then remembered it was the first thing i checked when I got it... :p

C'est normal.

Charges a 2-3A (si c'est une large, 1A si c'est une mini).

Ta batterie fait des faux peaks et ton chargeur arretes.

Et achètes une nouvelle bat... on est pas en '96 pour rouler sur des NiCd...

It's a NiCD battery. Maybe it has bad charge memory now.

Use NiMH's, they're much better and don't care when/how long you charge them.

J'sais ben, mais pour ce que je fais avec... et le gun dans laquelle je la mets vaut apeupres 100$ :p
J'vais essayer a 2-3A voir ce que ca donne. Quand j'aurai une coupe de piasses de libre j'investirai dans du NIMH :D

According to the whole "pulse charger" gimmick, it's supposed to break the crystals causing memory. I'll do a full discharge, but I have to space out the sessions. It does it at 4A, and it gets way too hot for my liking. I've already done two full discharges in the past, and didn't use it that much to begin with.


UPDATE : Charged it, started at 8.04V according to multimeter. TWO cycles, at 3A. Didn't even get warm, and instead, went down to 7.79V. What. The. Derp.

Ben elle est morte...

Si tu veux passer me voir, je peux essayer de la revivre avec mon ICE...

Bah, m'as voir a ca, elle a remonté a 7.89 pendant la nuit pour une raison quelconque... Je vais la remettre sur le wart charger si je peux la monter plus que 8.04, sinon, j'acheterai juste une NIMH comme tu dis :P

Au moins mon chargeur a rien!

Throw it away then, and buy a good new battery.

The funny part is, the wart charger actually got it up to 8.35V just now. If I could only find the output of that thing, I could try it on my charger, the max being 5.5A

UPDATE : I'ts down to 8.17V after 45 minutes

Quelle capacite ta batterie? (En theorie)

Bah, c'est marqué 1200mah dessus.
A l'as descendu a 8.17V en 45 minutes, de 8.35V. J'pense qu'a se mange toute seule.
