Cordless Drill Batteries

[Sir Tigger KC]

The batteries in my 4 or 5 year old Makita drill have died. 

I can get replacements on ebay for about £30 which seems reasonable, but they are more powerful than the originals. 3ah as opposed to the 1.3ah that the OEM batteries are. 

Any issues with this?    As I understand it, it means that they'll last longer, but I don't want to burn the motor out.... 

[Bigron]

You won't burn the motor oput as long as the VOLTAGE is the same; the 3Ah figure means that they have managed to get a greater electrical capacity in the same physical size, so as you surmised, it will last longer between charges.
Dedpending on how dead your original batteries are, there is a naughty way of, possibly, reviving them.
PM me for details if you are interested.

Ron.

[Sir Tigger KC]

Yes both 18V Ron. 

They are dead as a Dodo unfortunately. Can't get a charge into them at all. 

I saw a youtube vid where a guy was demonstrating replacing dead cells in drill batteries which seemed straight forward.  I need the drill soon though so havn't time to faff at the moment.

Just be sure to read the reviews of your chosen seller. Some are fine, some have been known to cause fires when charging  .

Got my dad some for his DeWalt drills off Amazon that were about 45% of the price of a DeWalt battery. Lasted 2 yrs so far, no issues

Yeah, be choosy, even more choosy if lithium.

[Sir Tigger KC]

Choosy is not a word I've ever been associated with. 

[Kevin Wood]

Just a word of warning... A mate of mine has just had his house burnt down by a cheapo garage worklight containing a lithium battery.

[Viral_Jim]

Yeah, be choosy, even more choosy if lithium.

Good point. My father's were NiCad, even so I was still cautious.

Back in the days when I used to do RC buggy racing, I've blown up a few NiCd packs by abuse charging them.  I recall one went spectacularly on the main straight during a final. Oops.

On Sunday, I saw a Lithium Polymer pop when a model plane lost control and hit the runway quite hard.

Mine lives in a dedicated pouch for that very reason...

Should probably finish the plane that it belongs to

I need more pouches. I have one small one, and from where I am currently sat, can see 15 Lipos

Might move them to the well ventilated shed in the farthest depths of the garden

Don't be gay. Its not as bad as a gas cylinder and a spark
