How To Repair A Battery Connection On A Flashlight With A Rechargeable Battery
Why Do Batteries Leak?
How many of you take encountered a corroded bombardment compartment in one of your consumer devices? Accept you wondered why do batteries leak, and ways how to forestall information technology?
No doubt that most of you take seen the 'white fluff' of bombardment corrosion. It migrates into the battery terminals. Typical aa battery corrosion from leaking. It creates a mess and may ruin the electronic device all-together.
– Here'southward Why battery corrosion happens.
– How to prevent bombardment corrosion.
– How to clean information technology upward the mess.
– Batteries that will not leak or corrode.
I'm referring to typical consumer batteries such as AA or AAA size.
(See below for Car Batteries / corrosion)
Energizer Guarantee | No Leak
UPDATE, Energizer guarantees that these particular batteries will Non corrode. I fabricated the switch and can adjure that none of them have leaked:
As of this writing, the best price I've seen for these batteries:
Analeptic MAX AA
(view on amzn)
Analeptic MAX AAA
What is the White Fluff Corrosion on the Bombardment?
Potassium Carbonate is the white fluffy corrosion that develops at the ends of the battery. It's near often seen at the Negative ( – ) end of the battery.
The "alkaline metal" of the battery is potassium hydroxide. It's the alkali equivalent of acid'southward hydrochloric acrid. This will leak out, forming a white "fluff" of potassium carbonate. It typically leaks on the negative end of the bombardment prison cell. Why? Patently the positive end is vented improve.
Why Do Batteries Leak?
Hydrogen Gas Out-Gassing | Poor Bombardment Seals
Equally batteries discharge, the chemistry changes and some hydrogen gas is generated.
This out-gassing procedure increases pressure in the battery.
Eventually, the backlog pressure level may rupture the insulating seals at the end of the battery, or the outer metallic canister, or both. Over again, the Energizer Max battery claims no-leak (mayhap better seals than other brands).
Dead Batteries may Leak (AA | AAA)
All batteries will slowly gradually self-belch over time. This will occur whether they are setting on the shelf (a much slower procedure) or installed in a device (which oft occurs much quicker). And expressionless batteries may somewhen leak, resulting in the "white fluff" corrosion.
Loftier Temperatures
Loftier temperatures can also cause batteries to rupture and leak (hot, summertime surroundings).
Why Do Batteries Corrode If Left Installed?
Consumer element of group i batteries (such as the common AA or AAA) tin can eventually leak and corrode while on the shelf. With that said, batteries that are left installed in devices are more probable to leak. Hither'south why…
Self Discharged & Parasitic Drain
These batteries volition gradually and naturally cocky-discharge. They will discharge even quicker when small-scale trickle currents slowly bleed the bombardment ('parasitic bleed'). Consequently this leads to a dead battery (or batteries) which will out-gas and corrode.
A slow parasitic battery drain is mutual in many devices. Information technology will slowly belch the batteries until they're 'dead'. Equally a issue, the batteries may somewhen leak.
A device that is left unattended for long periods of time (with the batteries installed) may drain down slowly and kill the batteries.
Examples
A clock brandish screen on a portable radio is ane practiced example of parasitic drain. When the device is turned off, the clock continues to draw downwards the battery, admitting very little. A 'detect me' dimly lit LED is some other case. Many modern devices have agile circuitry which is ever 'on' to some extent. This will slowly drain the batteries while you may not fifty-fifty realize it.
My stance:
How-to preclude battery corrosion in flashlights
- Don't purchase this brand: Duracell
- Buy this brand: Energizer MAX
Energizer MAX

How To Prevent Bombardment Corrosion In Electronics
Purchase Analeptic MAX brand batteries (shown higher up). They're guaranteed not to leak.
[ Read: Batteries That Won't Leak Or Corrode ]
And/Or, Remove the batteries from electronic devices that will not be used for a pregnant menses of time.
This will prevent a irksome belch of the batteries and therefore prevent leakage when the batteries get low or go dead. Expressionless or low batteries are more likely to leak.
Example
You might have a portable radio set bated for emergencies. Or perchance yous oasis't used it for months and months. You should remove the batteries from the battery compartment to prevent a potential deadening belch and the resulting leak and corrosion.
How To Clean Battery Corrosion
Alkaline Batteries:
To make clean upwards the corrosion 'fluff' caused by leaking ALKALINE batteries:
– Vinegar or Lemon juice.
– Soak and swab a Q-tip over the terminals.
Motorcar Batteries:
Batteries with an Acrid makeup (e.g. auto batteries), how to make clean upwardly battery corrosion:
– Mix a solution of baking soda and h2o to make a sort of paste solution.
– This will neutralize the acidic corrosion of the bombardment terminals.
