Can I charge ev warrior with standard battery charger?

Yes, But. 2 pack so 6volt each, I will assume standard lead acid batteries as the is common, and that is what the pic shows. depends on what you call standard charger, I would not do it with my 40 year old standard charger, although at a push, it will still charge them, but need to keep a check on them, later chargers, monitor the battery voltage, and adjust output to suit. All chargers work the same way, so basically yes, but keep a check on them, not running to hot etc. check voltage if you can. But they all work the same way, just later cells are used to the controlled cct of later chargers. especially with them being so called sealed, they still let gas escape, via a pin hole, If they get hot, to much gas, going out, reduces the effiency of the electrolyte, so will reduce the life, BUT as long as you keep checking them and stop if they get hot no problem, they will get warm anyway.

I need manual for power station by powerline model ps2000

I have the manual, but it shows no internal parts or wiring diagrams. Very likely you need to replace the battery. Best place is from eBay, UPG new UB12220 40696 AGM 12V 22AH 12Volt 22Amp sealed lead acid battery.

Terminals are slightly different so use the bolts that come with the battery (may be taped to the side). To access battery, remove 2 screws on each long side near the bottom, turn unit upside down, remove 4 screws on the base. Turn right side up and base will probably pop off with battery on top of it. Then you can test the battery to see if it will hold a charge, or if the charging circuit is at fault.

Expect sparks while connecting a new battery, so do not work on this near explosive vapors or gases. Charge battery for about 2 days and hopefully you'll be back in business.

My Vector model #VEC117FS has a battery that is dead and will not recharge. The replacement battery is VEC 191 according to the owner's manual. Where can I buy this battery or is it best to just buy a new...

There are many companies on the Internet that offer Sealed Lead Acid Batteries, which may be less expensive than replacing the light. I would suggest identifying the particular battery your light has and then check what's available on the Internet to make a decision on whether it is cheaper to replace the battery or the light.

The HP T100XR comes with 9ah batteries. They seem to be at the end of their life as I get little to no backup when the power is interrupted. I have a pair of 8ah batteries and was wondering if they can be...

Im like Mr., UPS, used to do 911 centers, vast huge banks of batteries, 50 or more.
the batteries, in UPS can be wired in different ways,
series, parallel and mix.
im not going to attempt to read your manual for you.
The charger wont care, its still lead and acid.
the charger watches voltages and does SOC tests to charge them.
i say ok but do not mix them. 8 and 9ah.
the internal resistance is different
all that really is different is the lead plate sizes.
9ah has later plate area....
only charge time and run times change
we also used a very expensive , battery internal resistance meter
that tells us that (cell(res)) , and can measure life, this way ,
we do that tests every 3 months and using the markers charts
we see ho much capacity is lost/ aged..
and replace them at 50% end of life point.
that is how we kept from having down time.

my guess 2 batteries in series, 24vdc, , that is how its strapped?
it will work.

2 batteries together labeled rt 1250

Not sure what the problem is, but most likely, it's two RT1250 batteries in parallel, with the label on one covered by the other battery.

An RT1250 is only 4.5AH, which would be a pretty short runtime. 9AH (two batteries paralleled together) would roughly double the runtime. That would be about 10 to 15 minutes for a 350VA UPS.

Specs and (USD) pricing are available here:
