new battery for my T23

[terki]

Hello!

My question is:

Is it better to buy new reconditioned battery with extended capacity such as 4400 or 5000 mAh [panasonic cells used]

Or to go with original IBM branded with SANYO cells, non-used but old with 3800 mAh?

THX for your help guyz!

Get a new T30 original IBM battery with 4400mAh.

thx!

Get a new T30 original IBM battery with 4400mAh.

Does it work with the T23?

[rkawakami]

Does it work with the T23?

Yes, Orevin is correct. The main battery designed for the T30 will fit into all of the T2x-series laptops. However, the reverse is not true; the T2x battery cannot fit into a T30 system.

[Vincent_k]

That mean's I'll have to go get me one T30 battery to replace my old and tired T23 battery

I cant find new original IBM T30 battery anywhere in germany, could any1 help?

[Thinkpaddict]

Is ordering from Lenovo Germany an option?

[Orevin]

Google for "akku ibm t30 site:de". Try also "batterie" instead of "akku".
I'm sure you will also find something on eBay, preisvergleich.de, preisroboter.de... usw... I saw IBM batteries at Conrad as well.

unless you need the power of a new battery, i recommend ebay seller "synaptic-systems." the batteries i purchased read 41wh, but last a solid hour with moderate use, slightly longer with hd off and brightness down a few notches. The meter isn't quite accurate as it goes from 55% down to 5% in a split second, but knowing your battery life is important. $20 shipped.

edit- oh you're in poland...well scratch that idea, but someone else may find it helpful.

you can get new original T30 batteries really cheap here:

there is no shop that sells them cheaper in europe than this 99 euro. just search the page for "T30"

These T-30 batteries are much more powerfull when using in T-23? How long more they last, comparing to original T-23 ones?

I'm looking for a battery for my "brand new" T-23... bought it in eBay for US$ 300, but the battery isn't good since holds charge for only 10 minutes. When reaches 85% it drops to 3%.

Sounds like Icefly and I were separated at birth. Exact same situation...waiting on an answer now as well =) Thanks!

The standard battery for a T20-22 has 3.6Wh (4.0Wh for a T23), while the T30 battery has 4.4Wh. So, there is up to more then 22% "more juice" in a T30 battery.

You might want to try reconditioning your battery, to see if you can bring some life back to your battery.

And separated by some millions of miles

Thanks for your tip tfflivemb2. I made the reconditioning and lifespan increased (from 15 minutes to 60 minutes) but this is not the ideal.

I disabled standby and hibernation alarm levels, did a full charge and then completey ran it down, for three times as stated in Battery Maximizer program tips, but now when reaches 75%, falls to 3%, and some minutes later the laptop shuts down.

Do you think I should try more this procedure or this may be bad for the battery?

Orevin, this is nice to hear from you!

[tfflivemb2]

No, I wouldn't try it anymore...it could cause damage to the battery. However, a battery that lasts an hour might be worth something here in the forum. You could probably sell it for $10-15 and use tha tmoney towards a new battery...or hold on to it as a back up.

[BlueDevilTide]

Would this battery work for my T23 then? I'm not sure if there are some T30 batteries that work and some that don't.

I have a related question about T23 battery use. I've researched a lot about Lith-Ion batteries on the net and most places say when doing a deep cycle recharge you should NEVER allow the remaining charge to drop below 20%. Other sources say that 'most modern' computers and other devices take this into account and wont allow you to discharge below this level automatically. Since my Thinkpad warranty and thus my online support from the factory has run out, and they won't answer my questions there anymore, My question to the forum is: Does the percentage amount displayed on the "Battery MaxMiser Guage" or when you go into the Battery Health screen, as the remaining charge, take this 20% into account? In other words, when it says there is 30% remaining is this actually 50% OVERALL in the battery or TRULY 30%? Then when deep cycling should we be allowing the battery to go to 0% on this guage or only 20%?

This would make a huge difference in properly conditioning the batteries, since if I only go to 20% on this guage as most sources recommend, then I may in fact only be going to 40% and not only wasting this extra charge per cycle, but also not properly initially conditioning it.

The reason I ask is that I have now had two supposedly brand new batteries which dropped from 100% to "needs replaced" on the Battery Health screen. One after just over 100 cycles (which has dropped to 50% of it's Designed Capacity) and the other after only 7 cycles (has already dropped to about 80% of its Designed Capacity)! I use it quite regularly about twice a week and both batteries were manufactured less than a year prior to the time I started using them. I NEVER allow them to get much away from room temp. When I'm not going to be using it for a couple weeks I discharge the batteries to 40% and store them on the fridge door in a ziploc as recommended. I am so careful I can't imagine anything I'M doing wrong that would cause them to go bad so quickly.

Also has anyone heard of any effects of airport x-rays on laptop batteries? Mine go through the carry on xray about once a month. The new one has only been through twice so far.

Any help would be appreciated.
thanks

you can check what power is related to your percentage by using the IBM battery maximizer tool. it gives Ah-ratings under battery informatin.

i think you should simply USE the battery. it's a consumable. if you only use 40 - 100 % load you will have to charge more often. this will also kill your battery (too many cycles).

so in total i think if you
a) charge often for smaller power makeup on the battery (40 -100%)
or
b) charge infrequently for higher power makeup (0 - 100%)

makes no big difference. the battery will die sooner or later.
