So far the one I tried was at Gilmore... and it was pretty much okay except they were a day late from their original estimated delivery date (1 week).

on repacking - safety of lithium ion/polymer (lipo) batteries:

base on my experience with lipo batteries sa R/C and readings on rechargeable lithium based batteries:

1) dapat binabalance ang charge ng bawat cells - usually done internally by the laptop charger na yun.
2) overcharging one cell will lead to weak batteries and will eventually have problems in charging (thereby causing explossion). kung may problem ang laptop charging system lang nangyayari eto.
3) too much power in charging of lithium batteries will cause heat build-up (thereby can also cause explossion). same din, may factor ang charging system ng laptop.
4) battery explossion (in reality) is really an extreme case scenario - masyado ng kapabayaan yun (like alam ng sobrang init e hindi pa rin ini-unplugged, faulty na ang power management/charging system ng laptop, overworked batteries).
5) NEVER drain your lipo batteries. They will die fast. Unlike NiCd and NiMH, Lipo doesn't have the "memory effect" ng charging. So limit the times that you over drain the charge. Most laptop have a power management system which halts the computer (hybernate) pag-mababa na ang charge.... similarly do not abuse that, kasi kahit naka hybernate it is still draining the battery. So charge it asap.

A 2 year life on the laptop battery na frequently used is already an excellent lifetime. Expect to replace them in 2 or 3 years. Kung hindi umabot ng ganun katagal yun, likely you always drain it or may problem ang charging system (hindi na babalance charge ang lipo cells).

Sa re-packing make sure that the battery is initially charged and "balance-charge"... kung hindi balanse yun, malamang hindi tatagal yun.

How to check the charge... you will need a digital volt meter... yung "poles" ng lipo battery ay usually more than two kasi bawat ends nito ay connected... so if you just try to poke one pole and match it with the other poles (one at a time) you will like get a voltage reading. A typical lipo cell will give at least anywhere around 3 to 3.7 volts (depending on the lipo).

Cells below 3v is indicative to a failing battery cell. Minsan kaya mahina na ang battery kasi one of the several battery cells are near dying na.

One recommended solution (which I have yet to try) is to charge that cell back to the right voltage. Then balance charge it with the rest of the batteries. Kung walang sira ang charging system ng laptop this should not be a problem.

Have you tried checking tipidpc.com?

Original is best. The few thousands "saved" with replacements is not worth it.

Actually this is also my problem, my NEO laptop is 7 months without the battery, I asked the NEO service center along Shaw Blvd. to source last January, upto now no answer, still sourcing. I'm now looking for a replacement but to no avail.

i recently inquired about a replacement battery for an asus eeepc 1000 at ActionLabs: Php3,800. Is this more or less the going rate these days?
