#battery

2025-05-02

want to replace #CMOS #battery in some old #laptop . researching #repair videos online, found some info for my models:

- HP Pavilion dv3, under wifi panel/slot, very accessible, need to check exactly which 2pin connector variant. doesn't seem to be completely flat yet

- Fujitsu-Siemens Amilo M 7400, seems to be under the keyboard, reasonably accessible, not yet had a look in mine to see which connector. battery is flat

- Asus W3N H004H, seems to be attached to the motherboard under the top panel (somewhere under the trackpad ish), but removing that seems to require lots of disassembly (video I saw for W3J model even detached the screen hinges??). battery is flat.

- Acer Aspire 5332, seems to be soldered to motherboard in some videos, battery seems ok

- eMachines 355 netbook, also seems to be soldered to motherboard, battery seems ok

- DIXONSXP Advent, no clue yet

already replaced the one in DELL P4 desktop (standard CR2032), have another desktop to check but I expect it to be trivial. expect my main desktop (new in 2019 iirc) to be good for another few years so won't touch it.

tips welcome, also recommendations for reputable repair shops in south #london uk that could do the tricky ones for me, and reputable online battery shops for the ones I can do

My next #Smartphone will be the #Samsung Galaxy #A55 as a Replacement for my actual #Galaxy #A52 that I like to use for the past 4 years. 😁

Almost 2 days of #battery life with 4-6 hours of screen on time, that's what I want from a modern smartphone, besides a decent #UI like #OneUI and software #support for 4-5 years.

I don't #game on a smartphone because it's not #enjoyable for me, hence the lack of good games and comfort.

#SolarUpdate time again.

It's been a very good month once more, well above the avg of the previous two years.

So a few figures first (previous years in brackets).

Solar Generation: 537kwh (2023: 468kwh & 2024: 425kwh)... That's really high for April, and for more context. In June 2024, we only generated 555kwh and 626kwh in 2023. 537kwh would be a very acceptable monthly figure for Jun-Aug

Export: 138kwh (2023: 163kwh(with smaller battery storage) & 2024: 98kwh (with larger storage)

We earned aprox £20 from export, which was deducted from the bill. So the bill for Gas & Electric inc all charges was £51.

In 2024, the April bill was £104, I don't have the bill from 2023 as we switched providers in Sept that year, so I'd have to hunt through emails from 2 years ago to try and find it... TBH, can't be arsed. 😆

We used 425kwh of electric on the house and imported 51kwh.

We also used the conservatory as a heater on the sunny days. Just opening the doors from the house to it, meant we didn't need heating for most of the month. In fact, we only spent £1.50 a day on gas 5 times, and only went over £2 a day twice. So our whole heating bill was about £34

We earned more in exported, than we spent on importing electric... but the daily standing charges made up 2/3 of the whole electric bill... and because of the export, the electric bill was around £17 for the month and around £34 for gas.

That's about a 50% saving on last years bill alone... the best one yet this year. We've seen 30-40% reductions on last years bill in previous months.

Can this weather last, or will we have a wet summer... No idea. But if it does, we could have a record year for generation. We need to beat around 4100kwh to do that. After the first 4 months, we've generated 1363kwh. We're still 7 weeks away from summer (4 if you count 1st June as the start rather than the equinox on the 21st).

A side effect of such a high generation, we've increased the credit on the energy account by a further £49 this month. They were predicting a £102 bill a few weeks ago, they lowered it to a £62 estimate a week or so back.

Interestingly, they're no estimating the May bill as £27... I'll be turning of the heating now for the summer.

DIY #mothtrap proof-of-concept.

Yes, those are #ultraviolet #LEDs.
Yes, that’s a light sensor on the right.
No, I’m not happy with the #leadacid #battery but they’re cheap, reliable and ideal for these experiments.

Now to find an enclosure… 🤔

I just learned the difference between AAA batteries and AA batteries.
AA is bigger than AAA

In numbers: #Solar and #battery storage powerhouse #Chile sets new #cleanenergy records theprogressplaybook.com/2025/0 “Chile has cemented its position as a frontrunner in the global energy transition, and the country is phasing out coal faster than any other developing economy.

According to modelling by the International Energy Agency, Chile is on track to eliminate coal-fired power by 2030 and get to over 90% renewables on an annual basis by then.”

I got a battery powered cooking set that could work on solar energy :3 it takes about 3-5% battery to bake an egg at full power (it should sustain full power for about 30 minutes).

Battery can be had for ~100-180€ (depending on source) and the induction cooker for about 30-40€, an optional matching solar panel costs about 50-100€
