NimH first charge + extra question

[skom25 2179]

Hi,

Two questions to NimH 4000 battery I bought:

1. Should I charge it first time with 1C or other rate?

2. Battery is bent, mainly on one side. Is this only visual issue or I should return it to shop?

1C charging is fine, it's what I do, but I think I'd take that back and get a straight one!

In some cars the batteries can be a tight fit and the bend will mean it might struggle to fit properly?

I think it is totally fine, but I will check.

If yes, is it safe to use it?

If that was my battery, I would return it and get another one that is perfectly straight as it should be.

Definitely plus one on that... Not just the small risk that a solder will fail but just for the general quality issue I would return it. Didn't you say the shop was 5min from home?

Edit: I think LRP should change their slogan to "Blue is better, not straighter"

Unfortunately not that shop :/ 

I wrote to them yesterday.

I forgot to add update.

I returned battery and in meantime, I ordered the same but 3000 version from different shop. It is straight. What I found, that rear plastic cap is bit on angle, but I do not want waste time on such things.

Now I am waiting for information from first shop.

If you happen to have an electronic scale, would you be able to weight that 3000mah battery by any chance? Thank you!

New slogan suggestion: "Blue is lighter, not straighter".

Thanks man.

Interesting that there would be differences. I would have thought that a Sub C cell was a Sub C cell, more or less the same size and containing more or less the same stuff and therefore all weighting more or less the same, but that is not the case. I think the 5000mah cells are even heavier which now seems logical.

Yep: more capacity = larger cells = heavier battery

I bought new battery, but it seems that weather will not let me to run this year too much. Packs which I already have are enough for few rides.

In that case, should I leave it and charge for the first time in a few months or just charge it now and recharge every month as others, even if not used?
