The 3.5Amp Hour is the best battery Panasonic made for the older style 15.6V drills.
However, the best deal on these batteries is in the package of TWO. Don't make the mistake I did and buy two singles, instead get the discount by buying two at a time in one package.
These are very good quality batteries. Don't bother with the 3.0Amp Hour models, the slightly lower price isn't worth it in my opinion.

Panasonic EY9231B 15.6-Volt 3.3 Amp Hour NiMH Pod Style Battery

I've owned two Panasonic EY6432GQKW Drills for nearly 7 years; they use these batteries.

Run-time. For the first 5 years, drill run time was very good due to these excellent NiMH batteries and their high amp-hour rating. When not in use they maintain a charge longer than the several NiCad tools I've owned. On big jobs, I keep a spare Panasonic battery in the charger so it will be ready when needed. On a construction job when the Panasonic is used frequently, a battery discharges about once a day. On rare days, I change out batteries twice. The battery does not get hot sitting in the charger for hours (or even days).

Battery longevity. Batteries began to noticeably deteriorate after 5 years of serious use. At the 6 year mark, my two drills were still usable, but run-rime was ½ of what it was, drill speed was reduced, power is diminished, and the charge only lasted a week. By comparison, the NiCAD batteries on my [previous] Porter/Cable, Delta, and Bosch cordless drills were dead within 3 years.

The Panasonic batteries had no useful power remaining after 6 ½ years, but the drill/drivers and chargers still worked as they should. So I bought new Panasonic EY9231B 15.6-Volt 3.3 Amp Hour NiMH batteries. Other than the drills looking seriously used, they behave as new again. I've been using cordless professional grade tools for a dozen years and whenever batteries died, new tool kits were the obvious replacement, since each generation of tools & batteries was technologically better. This Panasonic on the other hand (tool, charger, and battery life) was so good, that it made sense just to get new batteries.

Brought two replacement batteries in 2009...and they are not holding charge any more in 2011.only got two years thought I would get more life..the first two batteries did last longer and the drill is still good
As I am far away in the caribbean, think its Time to buy another brand...drill..

Doing my best to avoid nickel cadmium batteries that can not hold a charge after a few uses, I bought these upgraded batteries. They did not last 100 recharges. Great drill! But, batteries should be rechargeable for at least 500 charges.

I ordered this battery over a year ago for my Panasonic cordless drill. I charged it once and its still going strong.

These Panasonic battery's are better than any other aftermarket battery out there. Panasonic tools work hard and last forever. Period.

This was a very good purchase for me. My old batteries would no longer hold a charge so I was using a cheaper and less powerful drill and getting tired of not having the power I was used to with the panassonic. A battery store wanted $20.00 more for a cheaper 2.5 amp hr battery. The battery came in 3 days from the time I placed the oder. I am planning on getting a 2nd one so I can always have one ready to go. JDA

this battery works just like the that come wiyh the drill when i brought it 9 years ago. the one from 9 years ago is getting sleeppe os i will let it rest like somedays i have to when i get tried. would buy from again any day thanks kendell.

Drills suffer the same problem as HP color ink-jet printers. It's cheaper to buy a brand new printer than to replace all the ink. Here, the batteries cost about $80 from Amazon, so two for $160. Yet, a brand new drill only costs $193, and it comes with a new charger. Why not sell the old drill and buy a new drill instead?

EDIT: I found a value set which saves you $50 for two ($109 vs $160 separately): Panasonic 15.6 Volt 3.5Ah Ni-MH 2-Pack Battery--Value Pack So a new charger costs $100Panasonic EY0110B 7.2-Volt to 24-Volt Universal Charger for Ni-MH, Ni-Cd Batteries, a battery 2-pack costs $109, which I guess means they lose money on the drill itself? Not likely. It still may be worth it to sell the old one and buy a brand new replacement WITH a 1 year warranty. Even if you sold the old one for $75 on an auction site that rhymes with D-bay, you would at most pay $135 (after auction fees) for a brand new one. That is only $25 more than the cost of a 2-pack battery set alone. For an extra $25 and a little hassle you get a new drill, new charger, new batteries, and 1 yr warranty. Tough call? I don't think so.

Both my batteries had been recalled by Panasonic and I needed a battery quick to keep the cordless drill operational while they sent me the replacements. Amazon had the best price I could find and shipped promptly.
