OT: just bought a cordless leaf blower. Battery question

[samintx]

Well, not a question but thought..the instructions say to save battery don’t let it drain.OK to leave on charger for longer life.

This is opposed to what I Thoth I had been told about batteries

This is the B&D 2v interchangeable with that line of products..drill leaf blower etc

“ This is opposed to what I Thoth I had been told about batteries”

You are likely thinking of NiCad batteries, which needed to be drawn down to zero periodically to avoid patterning. Newer battery types (like NiMH and Li-ion) last longer if not completely drawn down. Better charging systems use intelligent charging to properly charge batteries. Follow directions in the manual.

And Li-Ion can reach an unrecoverable state if they are drawn to zero and then left to sit for an extended period of time.

Thanks folks

No battery, to date, at least for the consumer, should be allowed to be completely drained.

That said, NiCads, which are now fewer and far between, should be drained completely on occasion to recoup capacity.

This is not true for Li formulas or NMHi batteries.

Some batteries can be left on dedicated chargers indefinitely.

I do that with my motorcycle battery.

But for Li-ion appliances, I would not leave them on a charger unless I absolutely knew the charger was designed not to over charge long term.

Follow the charging instructions with your leaf blower, sam.

If you don't use and charge the battery regularly, you'd do well to charge it every two or three months, depending on their capacities.

As Gareth said, left dormant, they will die and cannot be charged.

The same applies to NiCad batteries.

I am guilty of that and am looking at four dead NiCads batteries because I forgot about them.

I assume that's either 12V or 2A.

The larger the capacity of the batteries - 2A, 4A, etc., the longer they can go between charges.

But learning my lesson, I'd check them every two months, during the winter or any long periods of non-use.
